Replace and Program ECU

WARNING: This page is about a different car, the 2011 Chevrolet Volt. However, it is still accessible from the selected car via links, so may be relevant.

To program a replacement body control module (BCM), perform the following procedure:

  1. Install EL-49642:  SPS programming support tool.
  2. Access the Service Programming System (SPS) and follow the on-screen instructions.
  3. On the SPS Supported Controllers screen, select BCM Body Control Module - Programming and follow the on-screen instructions.
  4. Perform the following for the appropriate ignition type prior to proceeding with the next step:
    • Key Ignition System: Key in the ignition and any additional keys must be away from the vehicle at least 3 meters.
    • Push Button Start System: Keyless entry transmitter must be in the console programming pocket. Refer to the Help selection button on the SPS Immobilizer Setup screen for the exact pocket location. All additional transmitters must be away from the vehicle at least 3 meters.
    5. NOTE: The following programming step may take between 10-12 min. and progress will appear to have stopped during this process. This is a normal security timer response and a restart should not be performed. If the DTC B389A set immediately after programming a replacement BCM, the Immobilizer Learn procedure was not properly completed. The Immobilizer Learn procedure needs to be performed again.
  5. On the SPS Supported Controllers screen, select IMMO Immobilizer Learn - Setup. On the next screen, select Body Control Module IMMO Learn with Existing Transponder or Remote Key and follow the on-screen instructions. When Immobilizer Learn is complete, press the Unlock button on the keyless entry transmitter to allow the keyless entry transmitter to exit the Immobilizer Learn mode.
    6. NOTE: When performing the Tire Pressure Monitor Sensor Learn during BCM setup, the EL-46079:  tire pressure monitor diagnostic tool must be used to activate each tire pressure sensor.
  6. On the SPS Supported Controllers screen, select BCM Body Control Module - Setup and follow the on-screen instructions.
  7. Check the driver information center display for additional messages regarding further calibration instructions. If there are no additional driver information center instructions present, programming is complete.
  8. At the end of programming, choose the "Clear All DTCs" function on the SPS screen.
