Vehicles Involved



Involved are certain 2008-2010 model year Cadillac CTS; 2010 model year Cadillac SRX; and 2007-2010 model year GMC Acadia and Saturn



OUTLOOK vehicles equipped with halogen headlamps. Dealers are to confirm vehicle eligibility prior to beginning repairs by using the Required



Field Actions section in the Global Warranty Management system. Not all vehicles may be involved.



For dealers with involved vehicles, a listing with involved vehicles containing the complete vehicle identification number, customer name, and



address information has been prepared and will be provided to US and Canadian dealers through the GM GlobalConnect Recall Reports, or sent



directly to export dealers. Dealers will not have a report available if they have no involved vehicles currently assigned.



The listing may contain customer names and addresses obtained from Motor Vehicle Registration Records. The use of such motor vehicle



registration data for any purpose other than follow-up necessary to complete this program is a violation of law in several states/provinces/countries.



Accordingly, you are urged to limit the use of this report to the follow-up necessary to complete this program.



Parts Information



Parts required to complete this program are to be obtained from General Motors Customer Care and Aftersales (GMCC&A). Please refer to your



"involved vehicles listing" before ordering parts. Normal orders should be placed on a DRO = Daily Replenishment Order. In an emergency



situation, parts should be ordered on a CSO = Customer Special Order.



Customer Reimbursement - For US



Customer requests for reimbursement of previously paid repairs for the recall condition are to be submitted to the dealer by December 31, 2012,



unless otherwise specified by state law. If this is not convenient for the customer, they may mail the completed form and all required documents to



the GM Customer Assistance Center.



All reasonable customer paid receipts should be considered for reimbursement. The amount to be reimbursed will be limited to the amount the repair



would have cost if completed by an authorized General Motors dealer.



When a customer requests reimbursement, they must provide the following:



- A completed Customer Reimbursement Request Form. This form is mailed to the customer or can be obtained through GM GlobalConnect.



- The name and address of the person who paid for the repair.



- Paid receipt confirming the amount of the repair expense, a description of the repair, and the person or entity performing the repair.



Important



If a reimbursement request is denied, dealers MUST provide the customer with an explanation, in writing, as to why the request was



denied. GM expects all reimbursement requests to be approved or denied within 30 days of receipt. If the denial was due to missing



documents, the customer can resubmit when the missing documents are obtained, as long as it is still within the allowed reimbursement



period.



Claims for customer reimbursement on previously paid repairs are to be submitted as required by GWM.



Customer Reimbursement - For Canada and Export



Customer requests for reimbursement of previously paid repairs to correct the condition described in this bulletin are to be submitted to the dealer

- Proof of ownership at time of repair.



- Original paid receipt confirming the amount of unreimbursed repair expense(s) (including Service Contract deductibles), a description of the



repair, and the person or entity performing the repair.



If the work was done by someone other than a GM dealership, the amount of reimbursement will be limited to the amount that the repair would have



cost GM to have it completed by a GM dealership.



Courtesy Transportation - For US and Canada



The General Motors Courtesy Transportation program is intended to minimize customer inconvenience when a vehicle requires a repair that is



covered by the New Vehicle Limited Warranties. The availability of courtesy transportation to customers whose vehicles are within the warranty



coverage period and involved in a product program is very important in maintaining customer satisfaction. Dealers are to ensure that these customers



understand that shuttle service or some other form of courtesy transportation is available and will be provided at no charge. Dealers should refer to



the General Motors Service Policies and Procedures Manual for Courtesy Transportation guidelines.

TECHNICAL



Bulletin No.: 13-08-116-001A



Date: March 22, 2013



Subject: Aftermarket ALDL or DLC Interface Devices Causing Multiple Issues



Models:



2016 GMC Truck Acadia AWD V6-3.6L Page 343



2006-2014 GM Passenger Cars and Trucks



Supercede:



This bulletin is being revised to add additional possible symptoms, clarify the language and revise the photos. Please discard Corporate Bulletin



Number 13-08-116-001 (Section 08 - Body and Accessories).



Condition



Customers may comment on various issues with their vehicle related to high or low speed data bus traffic. These concerns may be widely varied, but



some of the known issues are listed below.



The information contained in this bulletin is not meant to single out any one device or symptom, but to provide additional information that may be



useful for diagnosing issues that do not have other diagnostic methods to identify the root cause.



Note



This bulletin is being written with a focus on full size truck and full size van along with other fleet vehicles, but could apply to any vehicle.



Known Symptoms (not specific to any one device)



- The radio may not shut off after shutting down vehicle.



- Bus or LAN traffic may stay active leading to a discharged vehicle battery.



- Problems reprogramming modules either because of interference or the device will not allow the bus to power down.



- ONSTAR(R) may lose the ability to provide diagnostic data.



- Various engine and transmission performance issues with SES light set.



- Intermittent driveability issues.



- Reduced power message and codes.



- Stabilitrak(R) message and codes.



- C0561 stored in the EBCM leading to a traction control issue.



- No high speed LAN communication along with various communication U-codes.



- Transmission may not shift for one key cycle (TCM in default mode).



- Erratic gauge readings or flickering displays.



- SES, MIL or CEL light set and numerous DTC communication codes such as U0100, U0101, U186B and U1862.



- Diesel power-up devices causing no power in 4WD low range.



- Erratic electric power steering boost potentially associated with codes U2109, U2107, U2100, B1325, C0000.



- Service Tire Pressure Monitoring (TPM) system light illuminated.



-Cannot relearn TPM



- Specific to Hybrids:



- Reduced propulsion power message.



- Service high voltage charging system message.



Cause



If nothing else can be identified as the root cause of the issue after normal diagnostics as found in SI, check for a device plugged into the Assembly



Line Diagnostic Link (ALDL) or Data Link Connector (DLC) for tracking and/or maintenance interval scheduling. Monitoring devices, along with



other electronic accessories such as aftermarket cruise control, or police speed checking devices (RADAR or LIDAR) may cause one or more of the



concerns listed above.



Many of the problems described could be caused by an open connection on the HSCAN bus. Example: if the device only makes connection with one



CAN +, then it will cause bus errors and erratic ECU behavior.



2016 GMC Truck Acadia AWD V6-3.6L Page 344



These devices may be removed by the customer for use in another vehicle while theirs is brought in for service. The intent of this bulletin is to



identify a potential source of concerns that do not have other diagnostic methods to identify them. The examples below illustrate some of the devices



encountered.



Examples:



The monitoring device examples are not specific to any one design, and styles will vary.



Device W/Secondary DLC Connector



This device has another DLC connector on it. The rest of the harness along with the device can be placed out of sight hidden from the technician,



who may not notice the diagnostic connector is not in the factory location.

Fleet Tracking Module Plugged Into the DLC



Correction



If SI diagnostics do not identify the source of the issue and if the device is available, attempt to duplicate the condition, and then remove the device



to determine if the condition is eliminated.



If the customer's concern is resolved by removing the DLC interface device, inform the customer of the results, and that they should work with the



supplier of the device for further resolution.



If the condition is not eliminated with the device removed, continue diagnosing the vehicle with the appropriate Service Information.



Parts Information



There should not be any parts required. If on the rare occasion parts appear to have been damaged by the device or the installation of the device, this



would not be a defect covered under the New Vehicle Limited Warranty. For more information on Non-General Motors Parts & Equipment and



Original Equipment Alterations, please refer to Article 1.2.2.12 of the Service Policies & Procedures Manual. The repair order must be documented



correctly stating factual information on what alteration or product was identified on the vehicle.



Warranty Information



If ALDL interface devices are suspected as the root cause for a customer's concerns, submit a claim using the Z1111 labor operation to document the



concern as detailed in the latest version of Corporate Bulletin Number 09-00-89-016 "Warranty Administration - Labor Operation Z1111 -



Suspected Tampering or Vehicle Modifications, including submitting the claim under the appropriate labor operation and Customer Satisfaction



selection in Global Warranty Management.

Attention:



The information found in this bulletin is designed to be a single source for the majority of questions you may have about the Tire Pressure



Monitoring (TPM) Systems found on General Motors Vehicles. While comprehensive, the bulletin is divided into sections, so after reviewing the



whole document, you can reference just the section you need when further questions arise. A copy of this information may also be given to your



customer as the "FAQs" section is written to assist you in explaining the most common misconceptions about the system in an easy to understand



way. This bulletin does not apply to the Saturn Astra and does not apply to vehicles in Canada that are not equipped with Tire Pressure Monitoring.

This bulletin is being revised to add the 2011 model year. Please discard Corporate Bulletin Number 07-03-16-004B (Section 03 - Suspension).



Customer Concerns and Confusion



When a customer comments on a condition related to tire pressure monitoring, it is very important to distinguish between Check Tire Pressure /



Low Tire Pressure conditions and Service Tire Monitor system issues. Understanding the difference between the two distinct conditions will help



you distinguish between normal system operation (tire needs air) and a system malfunction.



There are two important differences between a Check Tire Pressure / Low Tire Pressure message/light and a Service Tire Monitor message



light:



- A Check Tire Pressure / Low Tire Pressure message/light will stay on solid and no system codes are set. The TPM system is operating as



designed. Correcting the tire pressure will resolve the issue.



- A Service Tire Monitor message/light will blink and system codes WILL set. There is a condition that should be diagnosed and corrected.



Tire Pressure Light



Service Tire Monitor System (light blinks, then stays on)



2016 GMC Truck Acadia AWD V6-3.6L Page 248



The Tire Pressure Light will blink for about one minute and a Service Tire Monitor message will be displayed when a system malfunction occurs.



For example: If one or more tire pressure sensors does not transmit information for 18 minutes of driving, the TPM system WILL set a code, display



a message, and BLINK the light for about a minute, after which the light will stay on solid for the remainder of the ignition cycle. If the system fault



is intermittent, the message/light may also be intermittent - on during some ignition cycles, off during others.



Low Tire Pressure Warning (light stays on solid)



If the TPM system detects a tire pressure below the threshold, the Check Tire Pressure message and the Tire Pressure Light will come on and stay



on. The message and light may be intermittent in nature, especially during cold weather.



Conditions That Will Cause the Low Tire Pressure Warning Message/Light to Display:



- The tire may have picked up a road hazard and/or have a slow leak.



- The tire pressure may not have been checked in the past six months.



- The air pressure in a cold tire may be at the pressure where the system is required to warn the driver. However, that same tire will rise in



temperature and pressure as the customer drives, causing the message and light to go out.



- The tires may have been rotated, pressures adjusted, and the new tire positions were NOT re-learned into the vehicle. This can occur on



vehicles that have two different placard pressures for front and rear tires.



- There may be a slow leak in one of the wheel and tire assemblies (Valve Stem, Wheel Rim, or Aluminum Wheel Porosity Leak). If this



condition is found, please refer to bulletin:



- #05-03-10-003F - Low Tire Pressure, Leaking Cast Aluminum Wheels (Repair with Adhesive Sealant)



- #04-03-10-001F - Info - Tire Puncture Repair Procedures for all Cars and Light Duty Trucks



The Effect of Outside Temperatures on Tire Pressures



Important



As a rule of thumb, tire pressure will change about 7 kPa (1 psi) for every 6锟斤拷C (10锟斤拷F) decrease in temperature - dropping when it gets



colder outside, rising when it gets warmer.



Tire pressure should be set to the specified placard pressure at the lowest seasonal temperature the vehicle will encounter during operation.



The correct action to avoid a Check Tire Pressure message due to extreme temperature changes is to do the following:



- Use an accurate, high quality tire pressure gauge.



- Re-learn the TPM sensors and adjust the tire pressure to the placard values after every tire rotation.



- Let the vehicle sit and adjust the tire pressure to the specified value when the tire temperature is at the lowest expected temperature.



- Never set the tire pressure below the placard value regardless of tire temperature or ambient temperature.



Important



On extremely cold days, if setting the tire pressure when the vehicle has been indoors, it may be necessary to compensate for the low outside



temperature by adding 21-27 kPa (3-4 psi) more than the placard pressure. At some later time, when convenient and when the tires are cold



(outdoors), the pressure should be re-checked and adjusted to the placard pressures if necessary.



Using the TPM Tool



TPM Tool J 46079 Software Updates and Hardware Update Kit



The J 46079 TPM tool is a valuable aid in diagnosing system faults with TPM systems. It is a software-driven tool that REQUIRES periodic updates



in order to work on new model cars and trucks. Failure to update the tool with the latest software version may result in possible misdiagnosis.



TPM Software Version 3.5 has recently been shipped to each GM dealership in the J 46079-30 TPM update kit. All future TPM software updates



will be posted in GM DealerWorld (U.S) or the GMinfoNET (Canada) as needed. Under the Support tab, access "TPM Downloads."



This update consists of two parts:



- A hardware update kit that consists of a custom rechargeable battery pack, battery cover with charging terminals, and a charging cradle with a



smart charger where the whole tool will fit into the cradle for charging (same concept as a cordless phone). This hardware update substantially



increases the life of the batteries and will assure that the TPM Tester always has full battery capacity.



- The software update will add new vehicles and also improve the speed of the tool's read-back ability and accuracy.



Sensor transmission signal strength is displayed in the upper left corner of the main display next to the tool's battery level display. When the tool is



used in both activate or scan mode, it will receive the sensor's transmission and indicate its signal strength. It is important to note the sensor's



transmission signal strength since it is a good indication of an accurate diagnostic.



TPM Tool J 46079 User Tips



2016 GMC Truck Acadia AWD V6-3.6L Page 249



Diagnostic Tip



The placement of the TPM Tester's antenna when activating a sensor is critical, especially with the latest software update. When activating a sensor,



the antenna tip of the TPM Test J 46079 must be placed on the sidewall, perpendicular to the tire, and close to the valve stem (see photo above).



This will assure proper activation of the sensor. If the antenna of the TPM Tester is placed either on the valve stem or on the wheel itself, the tool



may not properly activate the sensor, causing improper diagnosis.



Diagnostic Tip



If you encounter a sensor that does not respond when activated by the tool, try activating another sensor that responded previously. This will help



you determine if the tool is able to activate the sensor or if you have a problem with one particular sensor.



Diagnostic Tip



When using the tool during a sensor learn procedure, use the "Activate" soft key on the tool. Press the key for one second then release and the tool



will perform an LF (low frequency - 125 kHz) activation cycle. You do not have to hold the key until the vehicle acknowledges. Holding the key



will just reduce battery life. The LF activation of the sensors wakes them up and forces them to transmit their IDs immediately. This allows a much



shorter sensor learn procedure than using the Delta P method.



Warranty Information



GM is very concerned about customer safety and tire performance. Anytime a customer brings a GM vehicle in for a tire or tire pressure monitoring



concern, we encourage our dealers to perform a complete check of tire conditions, pressures, and the TPM system if necessary. Under normal



circumstances, the condition of tires, TPM reprogramming during tire rotation, road hazard repairs, and checking/maintaining tire pressure are the



responsibility of the vehicle owner. GM Dealers should encourage customers to inspect/check and maintain their tires and tire pressure on a regular



monthly basis.



The tires and the tire pressure monitoring system are covered by the vehicle bumper to bumper warranty for manufacturing defects. It is GM's



responsibility to perform repairs when a defect exists. If no defect exists, the customer should be responsible for the tire/system check.



GM does not cover the normal inspection and maintenance of tires and tire pressure. The use of this labor operation E0716 is intended to identify



system defects and verify proper operation.



Warranty Information (excluding Saab U.S. Models)



E0716 - Diagnostic System Check - Tire Pressure Monitoring This labor operation should be used to check proper TPM system operation when a



customer brings their vehicle into the dealership with a Service Tire Monitor System message/light (blinks on startup, codes in system).



If a customer comments on a Check Tire Pressure / Low Tire Pressure message/light (light was on steady - no flashing), the tires should simply be



inflated to the proper pressure - this is not a warrantable repair.



E0719 - Washer, Lower Tire Pressure Warning Sensor Replacement This labor operation should be used whenever the rubber grommet is



replaced.



E0722 - Tire Pressure Indicator Sensor Replacement This labor operation should only be used when a System Malfunction has been confirmed



(by labor operation E0716) and the Diagnostic Trouble Code (DTC) corresponds to a Sensor Fault (DTCs C0750, C0755, C0760 and C0765).

TMP Frequently Asked Questions (FAQs)



TPM Frequently Asked Questions (FAQs)



The following are some of the most asked questions:



Q: What is a Tire Pressure Monitoring System?



A: The TPM system consists of four sensors (one in each wheel), which transmit wireless (RF) signals to a vehicle receiver (typically, the same



receiver that performs the keyless entry function), the Low Tire telltale, and the Driver Information Center (if equipped).



Q: Do all Vehicles Have Tire Pressure Monitoring?



A: Starting with the 2008 MY, all GM vehicles sold in the United States are equipped with tire pressure monitoring, to meet the mandates of



FMVSS 138. Some vehicles built prior to the 2008 model year or sold in Canada have tire pressure monitoring; check vehicle build and RPO



information to be sure.



Q: What does the Low Tire Telltale Look Like?



2016 GMC Truck Acadia AWD V6-3.6L Page 251



A: The Low Tire telltale is a yellow telltale that looks like an exclamation point inside of a horseshoe:



Q: When does the Low Tire Telltale Come On?



A: The Low Tire telltale MUST come on when a tire's pressure drops to 75% of the Recommended Cold Inflation pressure (the pressure value



printed on the vehicle placard - the yellow and white sticker in the driver door opening.)



There are several events that may cause a Low Tire warning:



- The tire may have picked up a road hazard and/or have a slow leak.



- The tire pressure may not have been checked in the past six months.



- The air pressure in a cold tire may be at the pressure where the system is required to warn the driver. However, that same tire will rise in



temperature and pressure as the customer drives, causing the message and light to go out.



- On vehicles where a different placard pressure is required between the front and the rear axles, the tires may have been rotated, pressures



adjusted, and the new tire positions were NOT re-learned into the vehicle.



- There may be a slow leak in one of the wheel and tire assemblies (Valve Stem, Wheel Rim, or Aluminum Wheel Porosity Leak). If this



condition is found, please refer to bulletin:



- #05-03-10-003E - Low Tire Pressure, Leaking Cast Aluminum Wheels (Repair with Adhesive Sealant)



- #04-03-10-001E - Info - Tire Puncture Repair Procedures for all Cars and Light Duty Trucks



Q: What does the TPMS Malfunction Warning Look Like?



A: The TPMS Malfunction indicator uses the same telltale as the Low Tire warning. The telltale will flash for the first 60 seconds of a KEY ON



event, and then go on solid.



Q: How can I tell the difference between a Low Tire and a system malfunction?



A:



- A Low Tire telltale will be on solid immediately after KEY ON, and will be accompanied by a CHECK TIRE PRESSURE message in the



Driver Information Center (if equipped).



- A system malfunction causes the telltale to flash for the first 60 seconds of a KEY ON event, and then go solid.



Tip



2016 GMC Truck Acadia AWD V6-3.6L Page 252



These behaviors repeat at each KEY ON cycle. The best way to diagnose the vehicle (if you're not sure which warning is being displayed) is to



KEY OFF and KEY ON again while watching the telltale and DIC messages.



Q: When are Diagnostic Trouble Codes Reported?



A: DTC's are reported ONLY when there is a system malfunction (flashing telltale). When a Low Tire (solid telltale) is displayed, that means that



the system is working exactly as it's designed to do - since there's no malfunction, there is no need for a DTC.



Q: What service is needed if the Low Tire telltale is on?



A: When a vehicle comes in with a Low Tire warning, the tires should be checked for any leaks or damage (from road hazards). After those have



been repaired (or if none are found), the tires should be inflated to the pressure shown on the Vehicle Placard - the yellow and white sticker in the



driver door opening. It is not necessary to relearn the sensors after correcting the pressure.



Q: Can Tire Pressure Monitoring be turned off?



A: Tire Pressure Monitoring is now a mandated safety system in the United States and cannot knowingly be disabled by an OEM nor an aftermarket



service provider (49 USC 30101).



Q: Can the Tire Type and/or Placard Value be changed, if aftermarket tires or wheels are installed?



A: The Tire Type (P Metric, LT Load Range C/D/E) and the Placard Value (Front Placard and Rear Placard, individually) are stored in the receiver



as calibrations and CAN be revised at a GM Dealership with a Tech 2. (The RCDLR Setup screens allow this.) Since the under-inflation threshold is



calculated as a percentage of the placard; correcting the placard values when different tires are installed will bring the vehicle back into compliance.



Q: What is Sensor Learning (Sensor Re-Learning, Sensor Training, Sensor Matching)?



A: Each sensor has its own unique identification code (ID) that is transmitted as part of its wireless signal. The receiver stores and uses these IDs to



determine which sensors are installed on the vehicle, and in which corner of the vehicle the sensor resides in (so that both the pressure information



provided in the Driver Information Center and the diagnostics are correct). Sensor Learning is the process that puts sensor ID information into the



receiver.



Q: When is Sensor Learning required?



A: Sensor Learning should be done when the vehicle's tires are rotated (since sensor position on the vehicle has changed) or when a sensor is



replaced/a new sensor is installed (since a new ID has been introduced to the vehicle). Sensor Learning is not required when simply correcting the



tire pressure resolves the vehicle problem.



Q: Why are dashes (" - - "), or a pressure value of 148 PSI (1020 kPa), sometimes displayed after a battery disconnect?



A: These displays come up after a battery disconnect/reconnect because the system is waiting for updated pressure information to be sent from the



tire pressure sensors. As each sensor transmits its information, the display is updated appropriately. Note that when dashes or 148 PSI (1020 kPa) are



displayed after a battery disconnect/reconnect, the System Malfunction warning is NOT displayed - because the system is still working properly, and



simply waiting for updated information from the sensors. Driving the vehicle above 20 mph (32 km/h) for 2 minutes gets the sensors talking, and



restores the correct pressure values to the display. It is also possible to restore the values by using the J-46079 TPM tool, using the "Activate"



function at each tire to activate the sensor (it is NOT necessary to put the system into Learn mode, in this special case).



Q: Is there a sensor installed in the spare tire?



A: No - a sensor is not installed in the spare tire.



Q: Are all of the sensors the same?



A: All of the sensors are not the same. They are supplied by different manufacturers, and send different RF signals to the vehicle. SOME of the



sensors are interchangeable, though - while they may look different, they DO send the same RF signal to the vehicle and MAY be used in place of



one another on a vehicle. See the Sensor Information Guide for more details about which parts are interchangeable.



Q: What size is the sensor nut?



A: The sensor uses an 11 mm hex nut for attachment.



Q: Will a tire pressure sensor fit in every wheel?



A: GM wheels (including Accessory Wheels available from GM SPO) are designed to accommodate tire pressure sensors. Many aftermarket wheels



also accommodate tire pressure sensors, but not all do. In some, the valve stem hole is placed in such a way (pointing straight into the middle of the



wheel, for example) that the motion detection components inside the sensor will not work correctly.



Q: Can the valve core be replaced?



A: The valve core can and should be replaced if it is removed from the sensor, but the replacement part depends on the material of the valve stem



2016 GMC Truck Acadia AWD V6-3.6L Page 253



(Refer to Service Bulletin # 08-03-10-005). Sensors with a rubber valve stem may use a standard brass valve core for replacement. Sensors with an



aluminum valve stem CANNOT use a brass core; instead, they require a nickel-plated valve core to protect against the corrosion that forms when



dissimilar metals come in contact. See the service parts guide for the correct GM part numbers to order and use.



Q: Can the grommet (and washer) be replaced?



A: The grommet (and washer) can and should be replaced if the sensor is removed from the wheel. The rubber grommet provides the air seal in the



valve stem opening, and a new one should be used to ensure a fresh seal after each service. See the service parts guide for the correct GM part



numbers to order and use.



Q: Can the rubber valve stem be replaced by itself?



A: The rubber valve stem is attached to the sensor electronics by a TORX screw. The valve can and should be replaced whenever the sensor is



removed from the wheel. See the service parts guide for the correct GM part numbers to use.



Q: Can the sensor be cleaned with a sharp pin?



A: NEVER use a sharp object to clean the pressure port of the sensor; it can be damaged and lead to part failure. If the dirt/grime/obstruction cannot



be removed with a cloth, replace the sensor.



Q: How long will the sensor's battery work?



A: The sensor is designed to last for 10 years or 150,000 miles (240,000 kilometers).



Q: Are tire pressure sensors compatible with aftermarket tire sealants?



A: Tire pressure sensors are not compatible with commercially-available tire sealants. Tire sealant materials can clog the pressure port of the sensor,



and lead to inaccurate pressure readings and improper Low Tire warnings. Additionally, some sealant products use materials that can degrade the



protective potting material that covers the sensor's electronics.



Q: Are tire pressure sensors compatible with GM Inflator Kits?



A: While tire pressure sensors are NOT compatible with commercially-available sealants, they HAVE been tested and ARE compatible with GM



Inflator Kits and the sealant that they use. After inflator kit use, the sensor should be inspected for any damage, and replaced/cleaned as needed.



Q: Are tire pressure sensors compatible with nitrogen inflation?



A: Tire pressure sensors are compatible with nitrogen inflation (normal air is already 78% nitrogen).



Q: How do changing outside temperatures affect tire pressure?



A: All gases change pressure as their temperature changes, and air or nitrogen are no exceptions. A good rule of thumb is that tire pressure will



change by about 1 psi (7 kPa) when temperature changes by 10锟斤拷 F (6锟斤拷C). Customers may experience this as temperatures change from summer to fall



and into winter - tire pressures will drop as the outside temperature gets colder. Customers may also experience this as temperatures change between



mid-day and overnight.



Q: How should tire pressures be set at PDI?



A: Tire pressure should be set to the specified placard pressure at the lowest seasonal temperature the vehicle will see during operation. The correct



action to avoid a CHECK TIRE PRESSURE message due to extreme temperature changes is to: Use an accurate high quality tire pressure gauge. Let



the vehicle sit and adjust tire pressure to the specified value when tire temperature is at the lowest expected temperature. Never set tire pressure



below the placard value regardless of tire temperature or ambient temperature On extremely cold days, if setting tire pressure when the vehicle has



been indoors, it may be necessary to compensate for the low external temperature by adding 3-4 psi (21-27 kPa) more than the placard pressure.



When convenient, at some later time, when the tires are cold (outdoors), the pressure should be re-checked and adjusted to placard if necessary.



Q: When will the J-46079 tool be updated?



A: TPM Software Version 3.5 has recently been shipped to each GM dealership in the J 46079-30 TPM update kit. This update consists of two



parts:



- A hardware update kit which consists of a custom rechargeable battery pack, battery cover with charging terminals, and a charging cradle with



a smart charger where the whole tool will fit into the cradle for charging (same concept as a cordless phone). This hardware update



substantially increases the life of the batteries and will assure that the TPM Tester always has full battery capacity.



- The software update will add new vehicles and also improve the speed of the tool's read-back ability and accuracy. Sensor transmission signal

or scan mode, it will receive the sensor's transmission and indicate its signal strength. It is important to note the sensor's transmission signal



strength since it is a good indication of an accurate diagnostic.



Q: Where should the J-46079 tool be positioned when it is being used?

Suspension).



Condition



2016 GMC Truck Acadia AWD V6-3.6L Page 285



Some customers may comment on a squawk, creak or itch type noise coming from the front suspension of the vehicle that may be more noticeable in



cold temperatures. This noise will most likely be heard during small to medium suspension travel. The noise may occur with the vehicle traveling



straight and/or during turns.



Cause



The cause of this condition at cold weather conditions may be due to the inside diameter of the front strut jounce bumper rubbing against the piston



rod of the strut, creating a slip-stick condition.



Correction



1. Identify the noise at the upper strut mount area. The concern may be on both sides of the vehicle.



2. Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle in SI.



Important



Take care not to damage the dust boot or mount cup during removal.



3. Pull the dust boot/jounce bumper assembly out of the strut mount jounce cup (1).



4. Slide the dust tube/jounce bumper assembly down to expose the top portion of the piston rod (1). A long screwdriver or pry bar may be



required to pop the dust boot/jounce bumper assembly from the mount cup.



5. Apply grease, GM P/N 12345579 (in Canada, 10953481), around the circumference of the piston rod ONLY in the exposed area (to top 25



mm (1 in) of the piston rod, measured from bottom of mount cup).



6. Raise the dust tube/jounce bumper assembly up to the mount cup.



7. Rotate the dust tube/jounce bumper assembly on the piston rod to ensure grease is distributed around the rod.



8. Re-seat the dust tube/jounce bumper assembly into the mount cup.



Note



After installing the dust tube/jounce bumper, the vehicle should be driven over a road surface that will input sufficient jounce travel into the



suspension, which will aid the dust tube/jounce bumper assembly into the mount cup (speed bump, driveway entrance, or other bump).



Note



For 2007-2008 model year vehicles built prior to March 01, 2008, if after performing the above repair the condition is still present, refer to

Concerns About Safety and Alterations to the Front Passenger Seat



Important



ON A GM VEHICLE EQUIPPED WITH A PASSENGER SENSING SYSTEM, USE THE SEAT COVERS AND OTHER



SEAT-RELATED EQUIPMENT AS RELEASED BY GM FOR THAT VEHICLE. DO NOT ALTER THE SEAT COVERS OR



SEAT-RELATED EQUIPMENT. ANY ALTERATIONS TO SEAT COVERS OR GM ACCESSORIES DEFEATS THE INTENDED



DESIGN OF THE SYSTEM. GM WILL NOT BE LIABLE FOR ANY PROBLEMS CAUSED BY USE OF SUCH IMPROPER SEAT



ALTERATIONS, INCLUDING ANY WARRANTY REPAIRS INCURRED.



The front passenger seat in many GM vehicles is equipped with a passenger sensing system that will turn off the right front passenger's frontal airbag



under certain conditions, such as when an infant or child seat is present. In some vehicles, the passenger sensing system will also turn off the right



front passenger's seat mounted side impact airbag. For the system to function properly, sensors are used in the seat to detect the presence of a



properly-seated occupant. The passenger sensing system may not operate properly if the original seat trim is replaced (1) by non-GM covers,



upholstery or trim, or (2) by GM covers, upholstery or trim designed for a different vehicle or (3) by GM covers, upholstery or trim that has been



altered by a trim shop, or (4) if any object, such as an aftermarket seat heater or a comfort enhancing pad or device is installed under the seat fabric



or between the occupant and the seat fabric.



Aftermarket Seat Heaters, Custom Upholstery, and Comfort Enhancing Pads or Devices



Important



ON A GM VEHICLE EQUIPPED WITH A PASSENGER SENSING SYSTEM, USE ONLY SEAT COVERS AND OTHER



SEAT-RELATED EQUIPMENT RELEASED AS GM ACCESSORIES FOR THAT VEHICLE. DO NOT USE ANY OTHER TYPE OF



SEAT COVERS OR SEAT-RELATED EQUIPMENT, OR GM ACCESSORIES RELEASED FOR OTHER VEHICLE APPLICATIONS.



GM WILL NOT BE LIABLE FOR ANY PROBLEMS CAUSED BY USE OF SUCH IMPROPER SEAT ACCESSORIES, INCLUDING



ANY WARRANTY REPAIRS MADE NECESSARY BY SUCH USE.



Many types of aftermarket accessories are available to customers, upfitting shops, and dealers. Some of these devices sit on top of, or are Velcro(R)



strapped to the seat while others such as seat heaters are installed under the seat fabric. Additionally, seat covers made of leather or other materials



may have different padding thickness installed that could prevent the Passenger Sensing System from functioning properly. Never alter the vehicle



seats. Never add pads or other devices to the seat cushion, as this may interfere with the operation of the Passenger Sensing System and either



prevent proper deployment of the passenger airbag or prevent proper suppression of the passenger air bag.

2009 and Prior Saab 9-7X



To improve safety, fuel economy and vehicle performance, a number of high strength steels are used in manufacturing General Motors vehicles.



These various high strength steels and their location in specific vehicles can be found in Service Information | Body Repair | Collision Repair | Visual



Identification.



To perform structural or collision damage repairs, it is often necessary to drill out (remove) resistance spot welds in order to separate the



components being serviced from the vehicle structure.



A variety of drill bits are available to remove these resistance spot welds, however the useful life of many of these drills is limited by the hardness of



the high strength steels.



The General Motors Collision Repair Technology Center has recently validated a *CryoCobalt(TM) drill bit that has been developed for use with



very hard metals. These drill bits performed with exceptional results and should allow for increased production and reduced overall cost related to



resistance spot weld removal. These drill bits can also be re-sharpened.



These drill bits are available directly from the manufacturer. Refer to the ordering information below.



*We believe this source and their products to be reliable. There may be additional manufacturers of such products/materials. General Motors does



not endorse, indicate any preference for, or assume any responsibility for the products or material from this firm or for any such items that may be



available from other sources.

Body - Stain/Film On Windshield Glass Perimeter



TECHNICAL



2016 GMC Truck Acadia AWD V6-3.6L Page 208



Bulletin No.: 09-08-48-006



Date: September 18, 2009



Subject: Clear Stain or Film on Inside Perimeter of Windshield Glass (Clean/Polish Glass)



Models:



2010 and Prior Passenger Cars and Trucks (Including Saturn and Saab)



2010 and Prior HUMMER H2, H3



Condition



Some customers may comment on a clear stain or film on the inside of the windshield glass. This condition appears along the outer edges of the glass



along the top, bottom or A-pillar areas. Normal glass cleaning procedures will not remove the stain.



Cause



The assembly plant uses a clear sealer/primer on the outer edge of the windshield glass to improve adhesion to the urethane adhesive that bonds the



windshield glass to the vehicle body. Excess sealer/primer may drip or flow onto the windshield and cause a stain. Once the sealer/primer dries, it



may appear to have etched the glass.



Correction



Note



A "white" type of toothpaste is recommended for this repair. Gel-type toothpaste may provide less satisfactory results.



Use a small amount of toothpaste on a soft, cotton cloth to polish the stained area. It may be necessary to wrap the cloth around a paint stir stick or a



similar tool to reach the lower corners of the windshield glass.



After polishing the glass, clean the inside of the windshield glass with a clean, damp, cotton cloth and verify all of the stain is removed. Do not use



any cleaners or solvents - use only clean warm water.

Date: December 11, 2009



Subject: Front Side Door Trim Separates, Gap Between Armrest and Pull Cup (Install Tie Straps)



Models:



2007-2010 GMC Acadia



Condition



Some customers may comment on seeing a separation or gap, shown above, between the armrest and pull cup on the driver or passenger door trim



panel.



Cause



2016 GMC Truck Acadia AWD V6-3.6L Page 229



Because it is not secured to the armrest reinforcement, the inner side of the molded pull cup pocket has a tendency to pull away from the armrest.



Correction



Install two tie straps following the procedure below:



1. Remove the door trim panel. Refer to Front Side Door Trim Panel Replacement - Left Side (Acadia) or Front Side Door Trim Panel



Replacement - Right Side (Acadia) in SI.



2. Drill two 6 mm (1/4 in) holes in the black inward-standing flange of the pull cup pocket at the locations (1) shown above.



Note



Approximate size of the tie strap should be 4.5 mm (0.177 in) width and 300 mm (12 in) length.



3. Install tie straps (1) , obtained locally, into each of the drilled holes. Route the strap through the larger holes in the armrest reinforcement and



secure as shown above.



4. Ensure that the tie straps are snug and are pulling the pull cup pocket upward, closing the gap to the armrest. Trim off the extra length of the



tie wraps.



5. Install the door trim panel. Refer to Front Side Door Trim Panel Replacement - Left Side (Acadia) or Front Side Door Trim Panel



Replacement - Right Side (Acadia) in SI.

Fuel System - TOP TIER Detergent Gasoline (Canada)



INFORMATION



Bulletin No.: 05-06-04-022G



Date: October 27, 2010



Subject: TOP TIER Detergent Gasoline Information and Available Brands (Deposits, Fuel Economy, No Start, Power, Performance, Stall



Concerns) - Canada ONLY



Models:



2011 and Prior GM Passenger Cars and Trucks (Canada Only)



Supercede:



This bulletin is being revised to update the model years and include an additional gasoline brand as a TOP TIER source. Please discard Corporate



Bulletin Number 05-06-04-022F (Section 06 - Engine/Propulsion System). In the U.S., refer to the latest version of Corporate Bulletin Number



04-06-04-047I.



A new class of fuel called TOP TIER Detergent Gasoline is appearing at retail stations of some fuel marketers. This gasoline meets detergency



standards developed by six automotive companies. All vehicles will benefit from using TOP TIER Detergent Gasoline over gasoline containing the



"Lowest Additive Concentration" recommended by the Canadian General Standards Board (CGSB). Those vehicles that have experienced deposit



related concerns may especially benefit from use of TOP TIER Detergent Gasoline.

Top Tier Fuel Availability



Chevron was the first to offer TOP TIER Detergent Gasoline in Canada. Shell became the first national gasoline retailer to offer TOP TIER



Detergent Gasoline across Canada. Petro-Canada began offering TOP TIER Detergent Gasoline nationally as of October 1, 2006. Sunoco began



offering TOP TIER Detergent Gasoline in March of 2007. Esso began offering TOP TIER Detergent Gasoline in May of 2010.



2016 GMC Truck Acadia AWD V6-3.6L Page 308



Gasoline Brands That Currently Meet TOP TIER Detergent Gasoline Standards



The following gasoline brands meet the TOP TIER Detergent Gasoline Standards in all octane grades :



- Chevron Canada (markets in British Columbia and western Alberta)



- Shell Canada (nationally)



- Petro-Canada (nationally)



- Sunoco-Canada (Ontario)



- Esso-Canada (nationally)



What is TOP TIER Detergent Gasoline?



TOP TIER Detergent Gasoline is a new class of gasoline with enhanced detergency and no metallic additives. It meets new, voluntary deposit



control standards developed by six automotive companies that exceed the detergent recommendations of Canadian standards and does not contain



metallic additives, which can damage vehicle emission control components.



Where Can TOP TIER Detergent Gasoline Be Purchased?



The TOP TIER program began in the U.S. and Canada on May 3, 2004. Some fuel marketers have already joined and introduced TOP TIER



Detergent Gasoline. This is a voluntary program and not all fuel marketers will offer this product. Once fuel marketers make public announcements,



they will appear on a list of brands that meet the TOP TIER standards.



Who developed TOP TIER Detergent Gasoline standards?



TOP TIER Detergent Gasoline standards were developed by six automotive companies: BMW, General Motors, Honda, Toyota, Volkswagen and



Audi.



Why was TOP TIER Detergent Gasoline developed?



TOP TIER Detergent Gasoline was developed to increase the level of detergent additive in gasoline. In the U.S., government regulations require that



all gasoline sold in the U.S. contain a detergent additive. However, the requirement is minimal and in many cases, is not sufficient to keep engines



clean. In Canada, gasoline standards recommend adherence to U.S. detergency requirements but do not require it. In fact, many brands of gasoline in



Canada do not contain any detergent additive. In order to meet TOP TIER Detergent Gasoline standards, a higher level of detergent is needed than



what is required or recommended, and no metallic additives are allowed. Also, TOP TIER was developed to give fuel marketers the opportunity to



differentiate their product.



Why did the six automotive companies join together to develop TOP TIER?



All six corporations recognized the benefits to both the vehicle and the consumer. Also, joining together emphasized that low detergency and the



intentional addition of metallic additives is an issue of concern to several automotive companies.



What are the benefits of TOP TIER Detergent Gasoline?



TOP TIER Detergent Gasoline will help keep engines cleaner than gasoline containing the "Lowest Additive Concentration" recommended by



Canadian standards. Clean engines help provide optimal fuel economy and engine performance, and also provide reduced emissions. Also, the use of



TOP TIER Detergent Gasoline will help reduce deposit related concerns.



2016 GMC Truck Acadia AWD V6-3.6L Page 309



Who should use TOP TIER Detergent Gasoline?



All vehicles will benefit from using TOP TIER Detergent Gasoline over gasoline containing the "Lowest Additive Concentration" recommended by



Canadian standards. Those vehicles that have experienced deposit related concerns may especially benefit from use of TOP TIER Detergent



Gasoline. More information on TOP TIER Detergent Gasoline can be found at this website, http://www.toptiergas.com/.

Body - Non-Approval of Clipping For Collision Repair



INFORMATION



Bulletin No.: 07-08-98-001A



Date: January 28, 2009



Subject:



Non-approval of "Clipping" (Sectioning of Two Vehicles) For Collision Repair



Models:



2000-2010 GM Passenger Cars and Trucks (Including Saturn and Saab)



2003-2010 HUMMER H2, H3, H3T



Supercede:



This bulletin is being revised to add model years through 2010. Please discard Corporate Bulletin Number 07-08-98-001 (Section 08 - Body and



Accessories).



General Motors does not approve the use of "clipping" to repair collision damage to vehicles. In the collision repair industry, "clipping" refers to



cutting two damaged vehicles through the windshield pillars, the rocker panels, and across the floor pan and joining the undamaged portions from



these vehicles to make the repair.



The use of "clipping" voids GM's New Vehicle Limited Warranty (and any variety of the GM Protection Plan, as well as GM's new vehicle service



part and corrosion warranties) for each part in the clip.



GM does not sanction clipping repair because it cuts across the major load-bearing paths of a vehicle and can reduce the structural integrity of the



repaired vehicle. This is extremely critical because of the increase in the use of Advance High Strength Steel (AHSS). Improper repairs can lead to



vehicle performance issues related to noise, vibration and handling problems.



GM recommends replacing body components at factory seams. When applicable, GM will provide a specific service part for collision repair frames,



or provide repair information on how to create specific parts from a complete service assembly. Frame repair procedures for select GM vehicles are



available at http://www.goodwrench.com/gmgoodwrenchjsp/gmspo/techrepair_index.jsp. These parts and procedures provide a practical and



cost-effective alternative to clipping. GM provides vehicle specific collision repair procedures which are developed to be in a location and fashion



2016 GMC Truck Acadia AWD V6-3.6L Page 184



that will yield panel strength comparable to the original panel strength. Replacing damaged parts of a vehicle designed to crush in a collision may



reduce occupant protection in a future collision.



GM has not tested or validated a "clipped vehicle" repair; therefore, GM cannot endorse this type of repair or confirm the crash performance during



a subsequent collision. GM recommends the use of genuine GM parts in repairs to help ensure the vehicle is returned to pre-collision condition.

Steering/Suspension - Wheel Alignment Specifications



WARRANTY ADMINISTRATION



Bulletin No.: 05-03-07-009C



Date: December 09, 2010



Subject: Wheel Alignment Specifications, Requirements and Recommendations for GM Vehicles



Models:



2011 and Prior GM Passenger Cars and Light Duty Trucks



Supercede:



This bulletin is being extensively revised to provide technicians and warranty administrators with an all inclusive guide for wheel alignments.



PLEASE FAMILIARIZE YOURSELF WITH THESE UPDATES BEFORE PERFORMING YOUR NEXT GM WHEEL ALIGNMENT



SERVICE. Please discard Corporate Bulletin Number 05-03-07-009B (Section 03 - Suspension).



Purpose



The purpose of this bulletin is to provide retail, wholesale and fleet personnel with General Motors' warranty service requirements and



recommendations for customer concerns related to wheel alignment. For your convenience, this bulletin updates and centralizes all of GM's Standard



Wheel Alignment Service Procedures, Policy Guidelines and bulletins on wheel alignment warranty service.



Important



PLEASE FAMILIARIZE YOURSELF WITH THESE UPDATES BEFORE PERFORMING YOUR NEXT GM WHEEL ALIGNMENT



SERVICE.



The following five (5) key steps are a summary of this bulletin and are REQUIRED in completing a successful wheel alignment service.



1. Verify the vehicle is in an Original Equipment condition for curb weight, tires, wheels, suspension and steering configurations. Vehicles



modified in any of these areas are not covered for wheel alignment warranty.



2. Review the customer concern relative to "Normal Operation" definitions.



3. Verify that vehicle is within the "Mileage Policy" range.



4. Document wheel alignment warranty claims appropriately for labor operations E2000 and E2020.



The following information must be documented or attached to the repair order:



- Customer concern in detail



- What corrected the customer concern?



- If a wheel alignment is performed:



- Consult SI for proper specifications.



- Document the "Before" AND "After" wheel alignment measurements/settings.



- Completed "Wheel Alignment Repair Order Questionnaire" (form attached to this bulletin)



5. Use the proper wheel alignment equipment (preferred with print-out capability), process and the appropriate calibration maintenance



schedules.



Important



2016 GMC Truck Acadia AWD V6-3.6L Page 176



If it is determined that a wheel alignment is necessary under warranty, use the proper labor code for the repair. E2000 for Steering Wheel



Angle and/or Front Toe set or E2020 for Wheel Alignment Check/Adjust includes Caster, Camber and Toe set (Wheel alignment labor time



for other component repairs is to be charged to the component that causes a wheel alignment operation.).



The following flowchart is to help summarize the information detailed in this bulletin and should be used whenever a wheel alignment is performed.



Verify Original Equipment Condition of the Vehicle



- Verify that Original Equipment Tires and Wheels or Official GM Accessory Tires and Wheels are on the vehicle.



- Verify that aftermarket suspension "Lift" or "Lowering" Kits or other suspension alterations have NOT been done to the vehicle.



- Check for accidental damage to the vehicle; for example, severe pothole or curb impacts, collision damage that may have affected the wheel



alignment of the vehicle; e.g., engine cradles, suspension control arms, axles, wheels, wheel covers, tires may show evidence of



damage/impact.



- Check to be sure vehicle has seen "Normal Use" rather than abuse; e.g., very aggressive driving may show up by looking at the tires and



condition of the vehicle.



- Check for other additional equipment items that may significantly affect vehicle mass such as large tool boxes, campers, snow plow packages



(without the snowplow RPO), etc., especially in trucks and cutaway/incomplete vehicles. Significant additional mass can affect trim height and



wheel alignment of the vehicle and may necessitate a customer pay wheel alignment when placed semi-permanently in the vehicle (Upfitter



instructions are to realign the vehicle after placement of these types of items. (This typically applies to trucks and incomplete vehicles that can



be upfit with equipment such as the above.)



Customer Concerns, "Normal Operation" Conditions and "Mileage Policy"



Possible Concerns



The following are typical conditions that may require wheel alignment warranty service:



1. Lead/Pull: defined as "at a constant highway speed on a typical straight road, the amount of effort required at the steering wheel to maintain



the vehicle's straight heading."



Important



Please evaluate for the condition with hands-on the steering wheel. Follow the "Vehicle Leads/Pulls" diagnostic tree located in SI to



determine the cause of a lead/pull concern. Lead/Pull concerns can be due to road crown or road slope, tires, wheel alignment or even



in rare circumstances a steering gear issue. Lead/pull concerns due to road crown are considered "Normal Operation" and are NOT



a warrantable condition -- the customer should be advised that this is "Normal Operation."



Important



Some customers may comment on a "Lead/Pull" when they hold the steering wheel in a level condition. If so, this is more likely a



"steering wheel angle" concern because the customer is "steering" the vehicle to obtain a "level" steering wheel.



2. Steering wheel angle to the left or right (counter-clockwise or clockwise, respectively): Defined as the steering wheel angle (clocking)



deviation from "level" while maintaining a straight heading on a typical straight road.



3. Irregular or Premature tire wear: Slight to very slight "feathering" or "edge" wear on the shoulders of tires is NOT considered unusual and



should even out with a tire rotation; if the customer is concerned about a "feathering" condition of the tires, the customer could be advised to



rotate the tires earlier than the next scheduled mileage/maintenance interval (but no later than the next interval). Be sure to understand the



customer's driving habits as this will also heavily influence the tire wear performance; tire wear from aggressive or abusive driving habits is



NOT a warrantable condition.



Important



Slight or mild feathering, cupping, edge or heel/toe wear of tire tread shoulders is "normal" and can show up very early in a



tire/vehicle service mileage; in fact, some new tires can show evidence of feathering from the factory. These issues do NOT affect the



overall performance and tread life of the tire. Dealer personnel should always check the customer's maintenance records to ensure



2016 GMC Truck Acadia AWD V6-3.6L Page 177



that tire inflation pressure is being maintained to placard and that the tires are being rotated (modified-X pattern) at the proper mileage



intervals. Wheel alignments are NOT to be performed for the types of "Normal" Tire Feathering shown in Figures 1-4 below.



Figure 1: Full Tread View - "NORMAL" Tire "Feathering" Wear on the Shoulder/Adjacent/Center Ribs



Figure 2: Tire Shoulder View Example 1 - "NORMAL" Tire "Feathering" Wear on the Shoulder



Figure 3: Tire Shoulder View Example 2 - "NORMAL" Tire "Feathering" Wear



Figure 4: Detail Side View of Tire Shoulder Area - "NORMAL" Tire "Feathering" Wear



Important



When a wheel alignment is deemed necessary for tire wear, be sure to document on the repair order, in as much detail as possible, the



severity and type of tire wear (e.g., severe center wear or severe inside or outside shoulder wear) and the position of the tire on the



vehicle (RF, LF, LR, RR). Please note the customer's concern with the wear such as, noise, appearance, wear life, etc. A field product



report with pictures of the tire wear condition is recommended. Refer to Corporate Bulletin Number 02-00-89-002J and



#07-00-89-036C.



4. Other repairs that affect wheel alignment; e.g., certain component replacement such as suspension control arm replacement, engine cradle



adjustment/replace, steering gear replacement, steering tie rod replace, suspension strut/shock, steering knuckle, etc. may require a wheel



alignment.



Important



If other components or repairs are identified as affecting the wheel alignment, policy calls for the wheel alignment labor time to be



charged to the replaced/repaired component's labor operation time rather than the wheel alignment labor operations.



Important



Vibration type customer concerns are generally NOT due to wheel alignment except in the rare cases; e.g., extreme diagonal wear



across the tread. In general, wheel alignments are NOT to be performed as an investigation/correction for vibration concerns.



"Normal Operation" Conditions



Vehicle Lead/Pull Due to Road Crown or Slope:



As part of "Normal Operation," vehicles will follow side-to-side or left to right road crown or slope. Be sure to verify from the customer the types of



roads they are driving as they may not recognize the influence of road crown on vehicle lead/pull and steering wheel angle. If a vehicle requires



significant steering effort to prevent it from "climbing" the road crown there may be an issue to be looked into further.



Important



A wheel alignment will generally NOT correct vehicles that follow the road crown since this is within "Normal Operation."



2016 GMC Truck Acadia AWD V6-3.6L Page 178



Mileage Policy



The following mileage policy applies for E2020 and E2000 labor operations:



Note



Wheel Alignment is NOT covered under the New Vehicle Limited Warranty for Express and Savana Cutaway vehicles as these vehicles require



Upfitters to set the wheel alignment after completing the vehicles.



- 0-800 km (0-500 mi): E2000/E2020 claims ONLY allowed with Call Center Authorization. Due to the tie down during shipping, the vehicle's



suspension requires some time to reach normal operating position. For this reason, new vehicles are generally NOT to be aligned until they



have accumulated at least 800 km (500 mi). A field product report should accompany any claim within this mileage range.



- 801-12,000 km (501-7,500 mi):



- If a vehicle came from the factory with incorrect alignment settings, any resulting off-angle steering wheel, lead/pull characteristics or the



rare occurrence of excessive tire wear would be apparent early in the life of the vehicle. The following policy applies:



- Vehicles 100% Factory Set/Measured for Caster/Camber/Toe - Escalade/ESV/EXT, Tahoe/Suburban, Yukon/XL/Denali,



Silverado/Sierra, Express/Savana, Corvette and Colorado/Canyon:



E2000/E2020 Claims: Call Center Authorization Required



- All Vehicles NOT 100% Factory Set/Measured for Caster/Camber/Toe as noted above:



E2000/E2020 Claims: Dealer Service Manager Authorization Required



- 12,001 km and beyond (7,501 miles and beyond): During this period, customers are responsible for the wheel alignment expense or dealers



may provide on a case-by case basis a one-time customer enthusiasm claim up to 16,000 km (10,000 mi). In the event that a defective



component required the use of the subject labor operations, the identified defective component labor operation will include the appropriate



labor time for a wheel alignment as an add condition to the component repair.



Important



Only one wheel alignment labor operation claim (E2000 or E2020) may be used per VIN.



Warranty Documentation Requirements



When a wheel alignment service has been deemed necessary, the following items will need to be clearly documented on/with the repair order:



- Customer concern in detail



- What corrected the customer concern?



- If a wheel alignment is performed:



- Consult SI for proper specifications.



- Document the "Before" AND "After" wheel alignment measurements/settings.



- Completed "Wheel Alignment Repair Order Questionnaire" (form attached to this bulletin)



1. Document the customer concern in as much detail as possible on the repair order and in the warranty administration system. Preferred



examples:



- Steering wheel is off angle in the counterclockwise direction by approximately x degrees or clocking position.



- Vehicle lead/pulls to the right at approximately x-y mph. Vehicle will climb the road crown. Severe, Moderate or Slight.



- RF and LF tires are wearing on the outside shoulders with severe feathering.



Important



In the event of a lead/pull or steering wheel angle concern, please note the direction of lead/pull (left or right) or direction of



steering wheel angle (clockwise or counterclockwise) on the repair order and within the warranty claim verbatim.



Important



In the event of a tire wear concern, please note the position on the vehicle and where the wear is occurring on the tire; i.e., the RF



tire is wearing on the inside shoulder.



2. Document the technician's findings on cause and correction of the issue. Examples:



- Reset LF toe from 0.45 degrees to 0.10 degrees and RF toe from -0.25 degrees to 0.10 degrees to correct the steering wheel angle from 5



degrees counterclockwise to 0 degrees.



- Reset LF camber from 0.25 degrees to -0.05 degrees to correct the cross-camber condition of +0.30 degrees to 0.00 degrees on the vehicle.



- Front Sum toe was found to be 0.50 degrees, reset to 0.20 degrees.



3. Print-out the "Before" and "After" wheel alignment measurements/settings and attach them to the Repair Order or if print-out capability is not



available, measurements may also be clearly and legibly handwritten into the Wheel Alignment Repair Order Questionnaire attached to this



bulletin.



4. Attach the Wheel Alignment Repair Order Questionnaire below along with the print-out of "Before" and "After" wheel alignment



measurements to the Repair Order and retain for use by GM.



2016 GMC Truck Acadia AWD V6-3.6L Page 179



Wheel Alignment Equipment and Process



Wheel alignments must be performed with a quality machine that will give accurate results when performing checks. "External Reference"



(image-based camera technology) is preferred. Please refer to Corporate Bulletin Number 05-00-89-029B: General Motors Dealership Critical



Equipment Requirements and Recommendations.



Requirements:



- Computerized four wheel alignment system.



- Computer capable of printing before and after alignment reports.



- Computer capable of time and date stamp printout.



- Racking system must have jacking capability



- Racking system must be capable of level to 1.6 mm (1/16 in)



- Appropriate wheel stops and safety certification



- Built-in turn plates and slip plates



- Wheel clamps capable of attaching to 20" or larger wheels



- Racking capable of accepting any GM passenger car or light duty truck



- Operator properly trained and ASE-certified (U.S. only) in wheel alignment



Recommendations:



Racking should have front and rear jacking capability.



Equipment Maintenance and Calibration:



Alignment machines must be regularly calibrated in order to give correct information. Most manufacturers recommend the following:



- Alignment machines with "internal reference" sensors should be checked (and calibrated, if necessary) every six months.



- Alignment machines with "external reference" (image-based camera technology) should be checked (and calibrated, if necessary) once a year.



- Racks must be kept level to within 1.6 mm (1/16 in).



- If any instrument that is part of the alignment machine is dropped or damaged in some way, check the calibration immediately.



Check with the manufacturer of your specific equipment for their recommended service/calibration schedule.



Wheel Alignment Process



When performing wheel alignment measurement and/or adjustment, the following steps should be taken:



Preliminary Steps:



1. Verify that the vehicle has a full tank of fuel (compensate as necessary).



2. Inspect the wheels and the tires for damage.



3. Inspect the tires for the proper inflation and irregular tire wear.



4. Inspect the wheel bearings for excessive play.



5. Inspect all suspension and steering parts for looseness, wear, or damage.



6. Inspect the steering wheel for excessive drag or poor return due to stiff or rusted linkage or suspension components.



7. Inspect the vehicle trim height.



8. Compensate for frame angle on targeted vehicles (refer to Wheel Alignment Specifications in SI).



Satisfactory vehicle operation may occur over a wide range of alignment angles. However, if the wheel alignment angles are not within the range of



specifications, adjust the wheel alignment to the specifications. Refer to Wheel Alignment Specifications in SI. Give consideration to excess loads,



such as tool boxes, sample cases, etc. Follow the wheel alignment equipment manufacturer's instructions.



Measure/Adjust:



Important



Prior to making any adjustments to wheel alignment on a vehicle, technicians must verify that the wheel alignment specifications loaded



into their wheel alignment machine are up-to-date by comparing these to the wheel alignment specifications for the appropriate model and



model year in SI. Using incorrect and/or outdated specifications may result in unnecessary adjustments, irregular and/or premature tire



wear and repeat customer concerns



Important



When performing adjustments to vehicles requiring a 4-wheel alignment, set the rear wheel alignment angles first in order to obtain proper



front wheel alignment angles.



Perform the following steps in order to measure the front and rear alignment angles:



1. Install the alignment equipment according to the manufacturer's instructions.



2. Jounce the front and the rear bumpers 3 times prior to checking the wheel alignment.



2016 GMC Truck Acadia AWD V6-3.6L Page 180



3. Measure the alignment angles and record the readings.



If necessary, adjust the wheel alignment to vehicle specification and record the before and after measurements. Refer to Wheel Alignment



Specifications in SI.



Important



Technicians must refer to SI for the correct wheel alignment specifications. SI is the only source of GM wheel alignment specifications that



is kept up-to-date throughout the year.



Test drive vehicle to ensure proper repair.
