2025 Chevrolet Tahoe PPV, RWDSECTION Programming an Existing or New Control Module
To program an existing or new control module, perform the following procedure:
- Ensure the EL-52100 (MDI 2) is used when programming the vehicle and verify it is working properly. Using the EL-47955 (MDI) will result in a programming failure.
- Verify all control modules are connected and communicating before attempting to program the K36 Restraints Control Module.
- Verify the key fob is inside the vehicle. If the key fob is not inside the vehicle, the serial data authentication configuration procedure which runs automatically at the end of the programming step will fail even though the programming appears to run successfully. If the serial data authentication configuration procedure fails, DTC U1962 will set and/or the setup step will fail or be incomplete.
- Place the vehicle on level ground (the vehicle must be level or the IMU setup may fail)
- Ignition/Vehicle OFF, ensure that the key fob is inside the vehicle and not moved for the duration of the programming to prevent an inadvertent power mode change during programming.
- Access the Service Programming System (SPS) and follow the on-screen instructions for the K36 Restraints Control Module.
- Perform the SPS function: Programming and follow the on-screen instructions.
- Perform the SPS function: Setup and follow the on-screen instructions.
- Clear DTCs.
