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



B0014 01, B0015 01, B0016 01, B0019 01, B0020 01, B0021 01, B0022 01, B0023 01



The air bag or seat belt retractor pretensioner high and/or low control circuit is shorted to voltage for 120 milliseconds.

B0014 0E, B0015 0E, B0016 0E, B0019 0E, B0020 0E, B0021 0E, B0022 0E, B0023 0E



The air bag or seat belt retractor pretensioner deployment loop resistance is less than 1.1 ohm for 120 milliseconds.



Action Taken When the DTC Sets



* The SDM requests the instrument panel cluster (IPC) to illuminate the AIR BAG indicator.



* The SDM will store a DTC, however if an event occurs the system will still attempt deployments.



Conditions for Clearing the DTC



* The condition for setting the DTC no longer exists.



* A history DTC will clear once 100 fault-free ignition cycles have occurred.

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.
