Reprogram ECU
To program an existing 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 - Programming and follow the on-screen instructions.
- 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.
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.
