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. 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 12V jumper or booster pack disconnected from the AC voltage supply. DO NOT connect a battery charger. Ensure the ignition is turned OFF, load on the vehicle’s battery such as; interior lights, exterior lights (including daytime running lights), HVAC, etc. may affect the download process. 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: If the Same Calibration/Software Warning is noted on the TLC or SPS Summary screen, select OK and follow on-screen instructions. The system will generate a warranty claim code (WCC) for documentation purposes only. Perform service information (SI) diagnostics to determine the cause of the condition. Use the applicable labor operation code when submitting a warranty claim. Do NOT use the WCC with the warranty claim submission. Important: When programming a module in GM’s new Vehicle Intelligence Platform, or VIP, the power mode (ignition) needs to be off or errors may occur. This involves the 2020 Chevrolet Corvette, Cadillac CT5 and CT4, as well as the upcoming full-size Chevrolet, GMC, Cadillac SUVs and Buick Envision. Serial Data Message Authentication also needs to have the ignition off. 1. Inspect the current radio software version. Navigate to Settings -> About -> Build Number -> Information “i” to view and verify the software version. If the build number is less than V152, update the radio software. 2. Install the software update via USB. Refer to A11 Radio: Programming and Setup in SI. 5644478 Page 6 December, 2020 Bulletin No.: 20-NA-237 5431209 Note: The screenshots above are an example of module programming and may not be indicative of the specific module that is being programmed.
