His work after Helene cannot be emphasized enough. God or Karma sure has a funny way of saying thanks.

Merry Christmas and lets not forget Fesivus.

How the hell does gm backorder a software update?

Same here. Has rain sense wipers if that matters.

I found it. Works on model year 2025 and up.

Hmmmm. haven't heard of that availability. Keep us posted.

Heated only seats (KA1) have the module under the passenger seat. Heated/cooled (KB6) seats are controlled by each individual blower assembly.

Need to remove door panel and inner trim that goes from front corner up , back and down to rear of the door. 2 screws and a retainer to remove.

Nope

Ideal conditions to reduce the time needed for the Video Processing Control Module to complete the calibration include: Note: It may be helpful to select the surround vision overhead view while having the vehicle in a parking lot with straight or grid line markings. If an area of the overhead image displays skewed lines, this can indicate there may be an issue with the respective camera’s mounting condition or orientation. Note: In the rare event of an unsuccessful calibration event, it may be necessary to drive vehicle at 5-8 kph (3–5 mph) to allow calibration to complete successfully. Note: In the rare event of an unsuccessful calibration event, it may be necessary to drive vehicle on a road or parking lot without curbs or lane marking lines near the vehicle to allow calibration to complete successfully. All moving points of vehicle access (doors, trunk/liftgate, fuel door, hood, etc) of the vehicle Must be closed and the corresponding vehicle access systems functional (no DTCs, etc). No vehicle body or structural damage that may affect proper camera mounting or line of sight All surround vision cameras properly mounted, fully connected, and appropriately connected to the proper terminal of the Video Processing Control Module. Vehicle driven reasonably flat and straight for at least 5 minutes. Vehicle speed between 32-40 kph (20–25 mph) Steering wheel angle less than 15° It is a good practice to wipe camera lens’ clean prior to alignment Vehicle should not be within 1.5 meters (5 feet) of a curb or roadside Dry weather, cloudy but bright sky

The calibration procedure is needed to have the Video Processing Control Module learn new cameras and their positions. The calibration is performed automatically by the Video Processing Control Module. If any one of the cameras is replaced on the Surround Vision Camera System, the camera image needs to be calibrated to the system. For this reason, the Video Processing Control Module performs a calibration during its power up and initialization during each ignition cycle in order to maximize the surround vision image quality. A new Video Processing Control Module will have built-in default values for camera learn. However, the Video Processing Control Module will automatically calibrate in order adapt to the vehicle. To allow the Video Processing Control Module to complete calibration, drive the vehicle. Driving the vehicle in the conditions listed below will reduce calibration time.

Don't know of any issues like that. Don't see any bulletins/campaigns.

New bulletin/Campaign for '21 -"24 Silverado, Sierra etc with 6.2 L87 engine. Has to do with engine sudden stop (blown). Very early. No parts available at this time. NOT ALL 6.2's are involved. Which ones is unknown. Dealers have a list of inventory to inspect and stop sale if inspection fails. No much of an inspection though. Check for P0016. If it is there then stop sale. If not then change oil and filter to 0-40, change oil fill cap to reflect new oil grade, send it. Again NO PARTS at this time.

It is highly unlikely a ground issue. P0641 involves an issue with a 5v reference circuit. Involves the PCM and between 5 to 12 sensors, depending on which engine.

Well, here is partial diagnosis of the outside air temp sensor per the General. Verify the scan tool ECM Ambient Air Temperature parameter is within 15°C (27°F) of actual ambient temperature. If not within 15°C (27°F) of actual ambient temperature Refer to Circuit/System Testing. If within 15°C (27°F) of actual ambient temperature All OK. Hard to believe, ain't it!

CJ2 it is. Check for 5v, 12v and grounds per diagrams. otherwise you will probably need a scan tool and diagnostic chart.

C49 is rear defrost. How about CJ2? Or better yet a VIN.

Automatic or manual hvac? RPO C67 or C42?

'22 LTD or New body? Standard, ext or crew? Did find a G301b on a new body style ext/crew cab at the bottom of the left hand B pillar.

Penzoil for decades. Never an engine issue.

#PIT3271P: Guidelines When Changing Tire And Wheel Size - (Jul 11, 2024) Subject: Guidelines When Changing Tire And Wheel Size Brand: Model: Model Year: VIN: Engine: Transmission: from to from to All* All* 2003-2023 All All All All * Except Silverado Med Duty and LCF Models Supersession Statement This PI was superseded to update the Models. Please discard PIT3271M.   The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.   Condition / Concern A request may be made for a variety of reasons to change the tire size on a vehicle. Recommendations / Instructions General Motors will ONLY support a tire calibration for tires that have been sized, tested and designed for the vehicle in question and its applications. The only way to confirm that a calibration is available would be to visit YOUR sales department. Using the sales order guide, if you can build a vehicle, using the same make, model year, trim, and meet any restrictions listed in the tire section, GM will have a corresponding calibration available. Note: When changing tire size for new vehicles prior to the first sale and/or a tire/wheel size that may require a different pressure or alter the cargo carrying capacity of the vehicle, refer to #12-00-89-007B: Dealer Responsibility for Cargo Carrying Capacity Labeling. Once the tire application has been confirmed per the sales guide, contact Techline Customer Support Center (TCSC) (English: 1-800-828-6860, French: 1-800-503-3222 ) to determine calibration availability. Please do not call Technical Assistance Center for these concerns. Note: There may be a cost to the customer for this service. This is NOT a feature that is covered under the manufacturer's warranty. Examples: First example - A customer with a 2019 Chevrolet Silverado 1WT Regular Cab built with 255/70/R17 tires would like to install a set of wheels and tires from a 2019 Silverado 1CX Double Cab, which came with 275/60/R20 size tires. Based on the order guide, the 1WT trim is only available with either 255/70R17 or 265/70R17 size tires. For this reason, a calibration will not be offered for this application. Second example - A customer with a 2018 Chevrolet Colorado 2LT Crew Cab built with 255/65/R17 size tires would like to install a set of wheels and tires from a 2019 Chevrolet Colorado Z71 with 265/65/R17 size tires. From the order guide, the 2LT trim is only available with either 255/65/R17 or 265/60/R18 size tires. For this reason, a calibration will not be offered for this application either.   Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.

I don't know the capabilities of that unit but you need access to gm service programming info. I think one can subscribe to it for a short time but it's not cheap.

Under IP right of steering column, above throttle pedal. Yes, needs programming.
