Replace and Program ECU
To program a replacement body control module (BCM), perform the following procedure:
- Install EL-49642 SPS programming support tool.
- Access the Service Programming System (SPS) and follow the on-screen instructions.
- On the SPS Supported Controllers screen, select BCM Body Control Module - Configuration and follow the on-screen instructions (if applicable).
- On the SPS Supported Controllers screen, select BCM Body Control Module - Programming and follow the on-screen instructions.
- 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.
- 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.
- On the SPS Supported Controllers screen, select BCM Body Control Module - Setup and follow the on-screen instructions.
- 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.
- At the end of programming, choose the "Clear All DTCs" function on the SPS screen.
- If ABS, Traction Control and/or Stabilitrak indicators are ON and DTC C0161 is set in the electronic brake control module after performing BCM programming and setup, do the following:
- Disconnect the scan tool from the data link connector.
- Ignition OFF, all access doors closed, all vehicle systems OFF, and all keys at least 3 meters away from the vehicle. It may take up to 2 minutes to power down.
- Ignition ON, verify DTC C0161 is in history. If not, repeat the above step to make sure the vehicle is in sleep mode.
- Use the scan tool to clear the DTCs.
The BCM Configuration is only required if this option is available on the SPS Supported Controllers screen.
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.
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.
