2019 Cadillac Truck Escalade AWD V8-6.2L Diagnostic Instructions Page 57


Circuit/System Description



During a side or frontal crash of sufficient force the inflatable restraint sensing and diagnostic module (SDM) will allow current to flow through the



deployment loop in order to deploy the air bag module. There are 2 shorting bars used within the module connector which will short together both



high and low circuits, when the connector is disconnected. This will prevent unwanted deployment of the inflator module during servicing.



Conditions for Running the DTC



Ignition voltage is between 9-16 V.



Conditions for Setting the DTC

Buick Expands Luxury Avenir Sub-Brand With 2019 Regal

Now Buick's smallest luxury sedan has a luxury Avenir trim.

Last week a General Motors Fleet Ordering Guide revealed a new trim for the 2019 Buick Regal, which had yet to be officially announced. We knew that Buick's Avenir sub-brand has been a huge success, so it only seemed like a matter of time before the company expanded the trim level to throughout its lineup. Lo and behold, Buick has officially announced the 2019 Regal Avenir, which will now sit as the highest trim level besides the performance-oriented GS model.

Buick says that half of all Regal Sportback buyers opted for the top Essence trim level, so it only made sense to add an additional luxury Avenir trim. Over the past four years, the demand for midsize cars priced from $30,000 to $40,000 has risen by 30%, which further increased Buick's readiness to introduce the Regal Avenir. Buick has yet to announce pricing for the 2019 Regal Avenir, but we expect it to sit somewhere between the $34,795 Essence trim and the $39,995 GS model. Official pricing should be available in early fall 2018, closer to when the car arrives at dealers.

Despite not knowing pricing, we do know what features will come in the Avenir trim. No surprise, there are a lot of them. As with other Avenir models, the interior features a noticeable upgrade courtesy of a Whisper Beige or Ebony theme with Ebony accents, unique diamond quilt-stitched front seats, embroidered headrests, and Avenir sill plates. Other standard features include Evonik Acrylite exterior lighting, a rear camera mirror, an air ionizer, and Buick's new cloud-connected infotainment system. The exterior also benefits from a three-dimensional mesh upper grille and 19-inch Pearl Nickel wheels.

The Avenir trim also rolls in driver assist and safety technologies that are optional on other trim levels including rear park assist, rear cross traffic alert, lane change alert, LED headlights with auto leveling, cornering lamps, and driver side auto-dimming mirrors. Adaptive Cruise Control is also available as an option. As with all other non-GS models, the Regal Avenir will be powered by a 2.0-liter inline-four producing 250 horsepower and 260 lb-ft of torque going out to the front wheels through a nine-speed automatic.

Somehow, The Buick Enclave Made Buick Popular Again

Obviously it's no reborn Grand National, but the Enclave is the right vehicle for the times.

Something happened to Buick back in 2008 when the first and so far only generation Enclave crossover hit the market. That something was increased sales from people younger than age 65. Before this, Buick had tried to appeal to younger buyers with the so, so horrible Skylark coupe. But the three-row Enclave was very different and well-to-do suburban soccer moms quickly turned it into something trendy. The Buick Enclave has been so successful that aside from a 2013 refresh, it really hasn’t changed all that much in nine years.

Inside and out, the design still looks fresh, especially compared to the smaller, yet boring looking Envision. And because of its age and how Buick refined it over the years, the 2017 Enclave remains a smart buy, as we’ve recently learned.

Powered by a 3.6-liter V6 with 288 hp and 270 lb-ft of torque, power is sent to either the front or all four wheels through a six-speed automatic transmission. Despite being heavier than most of its current competitors, the Enclave still manages to return a respectable, though not outstanding, 17/24 mpg city/highway. But perhaps one of the Enclave’s most attractive features is, like its previous generation Chevrolet Traverse and GMC Acadia corporate cousins, the usable third-row seat. Adults human beings can actually fit back there fairly comfortably, an issue that still plagues many new three-row crossovers today. Special thanks to Woodland Motors for letting us film the car.

Celebrate 4th Of July With The 10 Best American Cars Of 2018

2018 was a good year for American automakers.

Last year, we celebrated 4th of July with a top 10 list of the best American cars of the year. The list included the Ford GT, Dodge Viper ACR, Chevy Corvette Z06, Shelby GT350, Cadillac CTS-V, Ford F-150 Raptor, Chevy Camaro ZL1, Jeep Grand Cherokee Trackhawk, Tesla Model S, and Dodge Challenger Demon. This year, we wanted to update the list with 10 of the coolest American cars to come out in 2018, and since this is a brand-new year, we left off the awesome cars from last year's list.

2018 Dodge Challenger Hellcat Redeye

If there is one thing the 707 horsepower Dodge Challenger Hellcat didn't need, it was 90 additional horses. That didn't stop Dodge from creating the insane Challenger Hellcat Redeye, which now produces 797 hp and 707 lb-ft of torque from its 6.2-liter supercharged V8. The redeye name signifies that the Hellcat has been "possessed" by the more powerful Demon, and even features red eyes on the Hellcat logo. We want to shake the hand of the marketing boss who signed off on that.

2018 Chevrolet Corvette ZR1

Although it was recently outdone by the Hellcat in terms of power, the Corvette ZR1 should not be ignored. The ZR1 produces over 100 hp more than the Z06 (755 hp) from a new supercharged LT5 V8. Zero to 60 mph takes just 2.85 seconds with the automatic. The ZR1 has already taken down the Demon in a drag race, and will dominate the Dodge on a race track.

2018 Cadillac CT6 V-Sport

Though it is not an all-out V model, the CT6 V-Sport represents an important step for the Cadillac brand. This luxury flagship is now powered by a 4.2-liter twin-turbo V8, producing 550 hp. This engine will likely be tuned to produce even more power in future V models, and could even act as the base engine in the rumored mid-engine Corvette.

2018 Lincoln Navigator

On the luxury end of the spectrum, Lincoln has knocked it out of the park with the redesigned Navigator. The Navigator was once maligned as a gussied up Ford Expedition, but is now the benchmark of its segment. Even Land Rover should watch out for this wonderful SUV.

2018 Dodge Durango SRT-8

On the SUV front, Fiat Chrysler wowed us by stuffing the 707 hp Hellcat engine into a Grand Cherokee. While it is not quite as crazy as the Trackhawk, the Dodge Durango SRT-8 is still an extremely awesome SUV. The Durango SRT-8 produces 475 hp from a 6.4-liter HEMI V8, and even has a third row to take the kids to soccer practice.

2018 Ford Ranger

While we patiently wait for the new Bronco, Ford has brought back another model from its past. The new Ranger will offer another American alternative for the hot-selling Toyota Tacoma. The US-spec Ranger is powered by a 2.3-liter EcoBoost, producing an as-of-now unknown amount of power. In other parts of the world, Ford sells an off-road focused Raptor version, which will hopefully make its way to the US.

2018 Buick Regal GS

General Motors may have killed off its last RWD sedan, the Chevy SS, but it left us another performance sedan: the Buick Regal GS. The GS isn't as powerful as the SS, but does produce 310 hp from its 3.6-liter Camaro-sourced V6. Buick tuned the GS more for comfort, but it also works pretty well as a sport sedan.

2018 Tesla Model 3 (Performance Spec)

Elon Musk has been teasing the prospect of an all-wheel-drive, performance oriented Tesla Model 3, aimed at rivaling the BMW M3. Tesla has finally delivered with a sedan that can do 0-60 in 3.5 seconds, and travel 310 miles on a charge. The M3 and its competitors better watch out.

2018 Hennessey Exorcist

Last year, we included the Chevy Camaro ZL1 1LE on our top 10 list. That car has since been outmatched by the ZR1, but Hennessey built a special ZL1 meant to dethrone the Dodge Demon. It's called the Exorcist, and Hennessey tuned it to deliver an insane 1,000 hp.

2018 Volvo S60 T8 Polestar

America is a land founded by immigrants, so we wanted to include at least one non-American car on the list. Although it comes from Swedish automaker Volvo, the new S60 is actually built in the US. The most powerful S60 T8 Polestar is powered by a twin-charged four-cylinder mated to a hybrid drivetrain. Total output is 415 hp, which is extremely impressive for a four-cylinder. The S60 Polestar will also be among the rarest cars on the list, with only 20 examples coming to the US.

Buick Regal Could Be Next To Receive Luxury Avenir Trim

So what new luxury goodies will the Regal Avenir have?

Buick's Avenir sub-brand has quickly become a huge sales success. One in every four Enclave models sold is an Avenir, and the LaCrosse Avenir looks like a solid luxury sedan. Based on the success of Avenir, Buick would be silly not to expand the luxury trim level to more models. We recently drove the 2019 Buick Envision, which was extremely comfortable and could benefit from an even more luxurious Avenir trim.

Although the Envision would be a good candidate for an Avenir model, The Truth About Cars has uncovered a General Motors Fleet Order Guide that lists a different future Avenir model. The document lists a 2019 Regal Avenir, which will only be available with front-wheel-drive and the four-door sportback body style. As with other Regal models, the Avenir trim will be powered by a 2.0-liter four-cylinder turbo producing 250 horsepower and 260 lb-ft of torque going out through a nine-speed automatic transmission.

Standard equipment on the Avenir will include 19-inch wheels, LED headlights, auto-dimming side mirrors, and the Driver Confidence Package 1 (four-way power lumbar adjustment and a wireless charging panel). The eight-inch infotainment system will have built-in navigation and will be linked to an eight-speaker Bose audio system. The Regal Avenir will also include lots of standard safety features such as rear park assist, rear cross traffic alert, and blind spot monitoring. We didn't get to see any pictures of this new trim level from the order guide, but we should see it sooner rather than later.

2018 Buick Enclave Review

The previous Buick Enclave was in production for a full 10 years and while it was a smooth and capable SUV, the fully redesigned 2018 model was long overdue. Aside from the obvious visual differences, the new model ushers in a raft of new technological and safety devices.

What’s it like inside?

The Enclave has always been a luxurious vehicle and this new model adds a modern touch to the cabin as well as some welcome features such as three-zone climate control and LED ambient lighting accents.

2018-2019 Buick Enclave Central Console

The Enclave looks and feels like a premium product even in base trim and most surfaces are covered in high-quality materials, it is configured solely as a 7-seater, the first two rows seat four and offer a high degree of comfort for adults of all sizes.

The third row is tasked with seating the remaining three occupants. If those three occupants happen to be adults then they will not enjoy the same sort of comfort as the passengers up front but two shorter adults will have no problems even on longer trips. This is partly to the enlarged interior dimensions and even the cargo space remains generous with all the seats up.

How does it drive?

The old car was more of a relaxed cruiser than a sharp driving tool and the new model retains that effortless cruising ability while offering a bit more dynamic ability.

Base models are front-wheel-drive while higher trim levels get all-wheel-drive. All versions offer good cornering abilities although the AWD models will be the preferred choice for slippery surfaces.

The ride is smooth and unflustered on most road surfaces and top Avenir trim get adjustable dampers that can help improve handling levels. Active noise cancelling aids in keeping the cabin quiet at highway speeds.

What about the performance?

The new Enclave makes 310 horsepower and 266 lb-ft of torque from its 3.6-liter V6, mated to a new 9-speed automatic transmission, performance levels are a step up from the previous model. The 0-60mph time is in the low 7-second range and the Enclave feels eager and responds enthusiastically to throttle inputs.

Front-wheel drive is standard with all-wheel drive optional on higher trim levels, fuel economy ratings are almost identical with a combined 21mpg on FWD models, dropping one mpg for AWD versions.

What are my options?

The base 1SV trim comes relatively well equipped and you get some notable standard features such as an 8-inch infotainment system with Bluetooth and smartphone compatibility, keyless entry and start function, rear parking sensors, LED headlamps, heated power adjustable front seats and 18-inch wheels. This trim is FWD only.

Essence trim adds leather seats and a driver confidence package which includes lane change alert with side blind zone alert and rear cross traffic alert. AWD is optional and a Trailering package can be specified as well.

2018-2019 Buick Enclave Front Three-Quarter Right Side View

Premium trim further improves safety levels with front parking sensors and luxury levels are elevated with ventilated front seats, heated second row seats, power-folding third row seats and a premium Bose audio system. A Buick Experience Package adds dual sunroofs, 20-inch rims and includes the aforementioned trailering package.

The Avenir trim level includes all of the above and adds an upgraded infotainment system with navigation, dual sunroof, surround vision with full display inside rearview mirror, unique styling elements and 20-inch alloy wheels. You also get a chestnut/ebony interior color scheme with contrasting seat stitching and piping.

The Avenir Technology package adds adaptive cruise control, forward automatic braking, active grille shutters and a premium suspension package.

The Verdict

The 2018 Buick Enclave is a much improved mid-sized three row SUV and offers a thoroughly modern design with luxury levels that approach far pricier European rivals.

A range of trim levels offer shoppers a variety of equipment and luxury options although opting for the top trim pushes pricing levels uncomfortably high. Stick to the mid-range Essence or Premium trim, choose FWD unless you really need the extra traction and the Enclave is a highly competitive luxury SUV.

What's Going To Happen To Buick If GM Sells Opel To The French?

Rebadging Opels as Buicks will eventually end. Then what?

Last week we learned that GM and PSA Group, which owns Peugeot and Citroen, were in advanced negotiations over the sale of Opel from the former to the latter. The Opel division, as you’re probably aware, has been GM’s star European division since 1947. So why is GM anxious to get rid of it? Because the European car market is insanely competitive, even more so than in the US, believe it or not. GM simply doesn’t need Opel anymore, especially since Opel has lost about $9 billion since 2009. So why does PSA want Opel?

Because, according to Automotive News, Opel could help it improve its market position in Europe thanks to the brand’s strength in certain markets where PSA is not, according to an analyst with Moody’s in a recent Bloomberg report. We’ll probably found out later this week whether or not a deal, said to be valued at around $2 billion, can be reached. In the meantime, we’re wondering what’s going to happen to Buick, a brand that relies upon a few rebadged Opels, specifically the Verano, Regal, Cascada, and the Encore, for its hot-selling lineup? Let’s break this down model by model: the Verano, a rebadged Opel Astra, has already ceased production for the US due to slow sales in the era of the crossover.

The LaCrosse sedan is already based on an existing GM platform. As for the most successful Opel-Buick model, the hot-selling Encore subcompact CUV, originally the Opel Mokka, don’t expect anything to change; the Encore isn’t going anywhere. Refreshed for 2017, the current generation will live out its lifecycle and will eventually be replaced by an all-new model that, like the new mid-size Envision CUV, will most likely be developed and even produced in China. The Cascada convertible dates back to 2013 and likely won’t be replaced once it’s discontinued, at least not right away. As for the Regal, its future remains uncertain. A complete redesign, based on the Opel Insignia, will soon debut, but it’s unknown at this point how long the new Regal will last.

What could end up happening, at least in the near term, is retaining the Regal status quo. Opel, under PSA, would simply continue building the Regal for GM, but only as long as it remains financially viable for both companies. Assuming the new Regal continues to sell well, then eventually we’ll probably see GM switch it to one of its own platforms. It could even become the corporate cousin of the Chevrolet Malibu. A redesigned three-row Enclave CUV, which never came from Opel, will debut in just a few weeks’ time, but it’ll share a platform with the just revealed Chevrolet Traverse. And so there you have it. Buick can very much survive and thrive without Opel, yet another reason why GM no longer needs to support a financially draining brand.

3. Key ON, engine OFF. The test light should be dull or OFF.



锟斤拷 If the test light is bright, test the indicator dimming control circuit for a short to voltage condition. If all circuits and connections test



normal, replace the BCM.



Note: When the DRL sensor turns the headlights OFF, the indicator dimming control circuit voltage, TCSCS X1 pin 4, will go from a



diagnostic B+ to a true B+.



4. Place a shop light on the DRL sensor. When the headlights go out the test light should illuminate brightly.



TCCM



1. Key OFF. Disconnect the X1 connector at the TCSCS.



2. Key ON, engine OFF.



3. Using the L-BU probe J 35616-64B, test for 4.5-5.5 V between the 5-volt reference circuit, TCSCS harness X1 pin 11 and a good ground.



锟斤拷 If the voltage is greater than the specified range, test the 5-volt reference circuit for a short to voltage. If all circuits and connections test



normal, replace the TCCM.



锟斤拷 If the voltage is less than the specified range, test the 5-volt reference circuit for an open/high resistance or short to ground. If all circuits



and connections test normal, replace the TCCM.



4. Using the L-BU probe J 35616-64B, connect a test light between the 5-volt reference circuit, TCSCS harness X1 pin 11 and a good ground.



The test light should illuminate dimly.



锟斤拷 If the test light does not illuminate, obtain a different test light and repeat step 4.



5. Key OFF. Wait 30 seconds for the TCCM to shut down.



Note: The TCCM must see the added resistance of the test light on the control circuit at key ON or the TCCM will shut the control circuit

GM May Be Next To Cut Sedan Range

The Cadillac ATS sedan has recently been axed but three sedans remain with a new model due in 2020 that will replace both the ATS and CTS. So, while they haven’t disappeared just yet, the range is shrinking and Cadillac’s SUV offerings are growing. For now, though, no official announcements have been made but the days of the traditional sedan, at least in the US, are numbered.

2019 Buick Regal Avenir Will Cost Over $10K More Than The Base Regal

But you're still getting a lot of luxury for a darn good price.

Earlier this month we learned that Buick will launch a Regal Avenir trim level for the 2019 model year. Avenir, as you likely already know, is Buick’s premium sub-brand that has become a massive success, with one in every four new Enclave crossovers sold is Avenir spec’d. That means additional profits and sales for GM’s premium brand, so it makes total sense to expand its Avenir sub-brand to other models.

According to Cars Direct, the 2019 Buick Regal Avenir will carry a base price of $36,195, and that includes the $925 destination fee. Compared to the base Regal Sportback, the Regal Avenir carries a significant price increase, $10,200 to be precise.

The top-of-the-line Regal GS, however, begins at $39,995. Think of the Avenir trim as Buick’s version of GMC’s Denali; same basic car, only with many premium features piled into a single and far more expensive package. It’s really brilliant business on GM’s part. So, what will buyers get in the 2019 Regal Avenir? The interior will feature several upgrades, among them Whisper Beige or Ebony theme with Ebony accents, diamond quilt-stitched front seats, embroidered headrests, and Avenir sill plates. The exterior will be enhanced with 19-inch wheels, a unique grille, and Acrylite exterior lighting. Owners will also enjoy Buick’s new cloud-connected infotainment system, a rear-view camera, and an air ionizer.

Under the hood will be the familiar 2.0-liter inline-four engine with a total of 250 hp and 260 lb-ft of torque, which is sent to the front wheels through a nine-speed automatic. Another benefit of the Avenir trim are the driver assist and safety technologies that come standard, including rear park assist, rear cross traffic alert, lane change alert, LED headlights with auto leveling, cornering lamps, and driver side auto-dimming mirrors. Adaptive Cruise Control will probably be optional.
