Bulletin No.: Service Bulletin Date: 22-NA-221 November, 2022 TECHNICAL Subject: Brand: Cadillac No Start, Slow Crank or Low 12V Battery Model: XT4 Sport XT4 Luxury Model Year: from to 2023 2023 VIN: Engine: from to SOP 1GYFZ9R48PF120785 SOP 1GYAZAR42PF120423 Transmission: Important: VIN breakpoint was established on October 19, 2022. No vehicle that was built after this date should have this condition. Involved Region or Country United States Additional Options (RPOs) Equipped with RPO Y19 Condition Some customers may comment on a slow crank where the 12V battery could be a low or in a dead battery condition resulting in no start that requires battery charging or battery replacement. Technician’s may find a parasitic drain of ~200 mA. Cause The cause of the condition may be that the BCM may wake-up and not return to sleep due to the electrical loading on the LIN bus used to control the heated seat modules. This results in higher parasitic battery drain leading to pre-mature battery discharge. This condition is only possible when the vehicle is equipped with both front and rear heated seats. The condition is intermittent and may not readily present. This condition is most likely to have an adverse effect on vehicles that are not regularly driven or are driven for limited miles when driven. Correction Reprogram the BCM with the latest calibration to keep LIN2 active to avoid LIN modules from being able to wake up BCM. Important: If the battery was low or dead, then charge and test the battery. The battery may require charging a second time before it will pass the test. Service Procedure Important: Service agents must comply with all International, Federal, State, Provincial, and/or Local laws applicable to the activities it performs under this bulletin, including but not limited to handling, deploying, preparing, classifying, packaging, marking, labeling, and shipping dangerous goods. In the event of a conflict between the procedures set forth in this bulletin and the laws that apply to your dealership, you must follow those applicable laws. Caution: Before downloading the update files, be sure the computer is connected to the internet through a network cable (hardwired). DO NOT DOWNLOAD or install the files wirelessly. If there is an interruption during programming, programming failure or control module damage may occur. Copyright 2022 General Motors LLC. All Rights Reserved. • • • Ensure the programming tool is equipped with the latest software and is securely connected to the data link connector. If there is an interruption during programming, programming failure or control module damage may occur. Stable battery voltage is critical during programming. Any fluctuation, spiking, over voltage or loss of voltage will interrupt programming. Install a GM Authorized Programming Support Tool to maintain system voltage. Refer to www.gmdesolutions.com for further information. If not available, connect a fully charged 12 V jumper or booster pack disconnected from the AC voltage supply. DO NOT connect a battery charger. Follow the on-screen prompts regarding ignition power mode, but ensure that anything that drains excessive power (exterior lights, HVAC blower motor, etc) is off Page 2 • November, 2022 Please verify that the radio time and date are set correctly before inserting USB drive into vehicle for programming, otherwise an error will result. • Clear DTCs after programming is complete. Clearing powertrain DTCs will set the Inspection/ Maintenance (I/M) system status indicators to NO. Important: The service technician always needs to verify that the VIN displayed in the TLC left side drop down menu and the top center window match the VIN plate of the vehicle to be programmed prior to using Service Programming System 2 (SPS2) for programming or reprogramming a module. • For the TLC application, service technicians need to always ensure that the power mode (ignition) is “ON” before reading the VIN from the vehicle’s VIN master module and that they do not select a VIN that is already in the TLC application memory from a previous vehicle. Bulletin No.: 22-NA-221 • If the VIN that shows up in the TLC top center window after correctly reading the VIN from the vehicle does not match the VIN plate of the vehicle, manually type in the VIN characters from the vehicle VIN plate into the TLC top center window and use these for programming or reprogramming the subject module with the correct vehicle VIN and software and/or calibrations. • The Engine Control Module (ECM) is the master module (for VIP vehicles) that TLC reads to determine the VIN of the vehicle. If the VIN read from the vehicle by TLC does not match the VIN plate of the vehicle, the ECM also needs to be reprogrammed with the correct VIN, software and calibrations that match the vehicle’s VIN plate. • The Body Control Module (BCM) is the master module (for GEM vehicles) that TLC reads to determine the VIN of the vehicle. If the VIN read from the vehicle by TLC does not match the VIN plate of the vehicle, the BCM also needs to be reprogrammed with the correct VIN, software and calibrations that match the vehicle’s VIN plate. Caution: Be sure the VIN selected in the drop down menu (1) is the same as the vehicle connected (2) before beginning programming. 5743643 Bulletin No.: 22-NA-221 November, 2022 Page 3 Important: If the vehicle VIN DOES NOT match, the message below will be shown 5877000 5644477 Important: Techline Connect and TIS2WEB screens shown above. Important: If the same calibration/software warning is noted on the TLC or SPS Summary screen, select OK and follow screen instructions. After a successful programming event, the WCC is located in the Service Programming System dialogue box of the SPS Summary screen. No further action is required. Refer to the Warranty section of the bulletin. 1. Reprogram the Body Control Module. Refer to K9 Body Control Module: Programming and Setup in the Service Manual. Page 4 November, 2022 Bulletin No.: 22-NA-221 5644478 Note: The screenshots above are an example of module programming and may not be indicative of the specific module that is being programmed. Module selection and VIN information have been blacked out. Important: To avoid warranty transaction rejections, you MUST record the warranty claim code provided on the Warranty Claim Code (WCC) screen shown above on the job card. Refer to callout 1 above for the location of the WCC on the screen. 2. Record Warranty Claim Code on job card for warranty transaction submission. Warranty Information For vehicles repaired under the Bumper-to-Bumper coverage (Canada Base Warranty coverage), use the following labor operation. Reference the Applicable Warranties section of Investigate Vehicle History (IVH) for coverage information. Labor Operation Description Labor Time *2889048 Body Control Module Reprogramming with SPS for Battery Drain 0.3 hr Add ONLY Use As Needed - Charge and Test Battery 0.2 hr *This is a unique Labor Operation for Bulletin use only. Important: **To avoid warranty transaction rejections, carefully read and follow the instructions below: • The Warranty Claim Code must be accurately entered in the “SPS Warranty Claim Code” field of the transaction. • When more than one Warranty Claim Code is generated for a programming event, it is required to document all Warranty Claim Codes in the “Correction” field on the job card. Dealers must also enter one of the codes in the “SPS Warranty Claim Code” field of the transaction, otherwise the transaction will reject. It is best practice to enter the FINAL code provided by SPS/SPS2. Bulletin No.: 22-NA-221 November, 2022 Page 5 Warranty Claim Code Information Retrieval 6125774 If the Warranty Claim Code was not recorded on the Job Card, the code can be retrieved in the SPS2 system as follows: 1. Open TLC on the computer used to program the vehicle. 2. Select and start SPS2. 3. Select Settings (1). 4. Select the Warranty Claim Code tab (2). The VIN, Warranty Claim Code and Date/Time will be listed on a roster of recent programming events. If the code is retrievable, dealers should resubmit the transaction making sure to include the code in the SPS Warranty Claim Code field. Version 1 Modified Released October 28, 2022 GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the information. WE SUPPORT VOLUNTARY TECHNICIAN CERTIFICATION
