Type Net Item 9106348* Verified Module Software or Calibration Level: Module Is Programmed with Same Level Software or Calibration 0.2 ZFAT N/A 9106349* Front View Camera Reprogramming with SPS 0.5 Important: * To avoid warranty transaction rejections, carefully read and follow the instructions below: • The Warranty Claim Code must be accurately entered in the “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 “Warranty Claim Code field of the transaction, otherwise the transaction will reject. It is best practice to enter the FINAL code provided by SPS2. Warranty Claim Code Information Retrieval 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. 4. Select the Warranty Claim Code tab. 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. Service Procedure Note: Carefully read and follow the instructions below. • 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. Service Update N212356230 Front Camera Module Inoperative Page 2 of 4 • 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. • 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. • 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 Important: If the vehicle VIN DOES NOT match, the message below will be shown Service Update N212356230 Front Camera Module Inoperative Page 3 of 4 5877000 5644477 Important: Techline Connect screens shown above.
