Body Control Module Programming and Setup

Special Tools

    • EL-49642 SPS Programming Support Tool
    • EL-46079 Tyre Pressure Monitor Diagnostic Tool

For equivalent regional tools, refer to Special Tools .

Note: 

   • DO NOT program a control module unless directed to by a service procedure or a service bulletin. If the ECU is not properly configured with the correct calibration software, the ECU will not control all of the vehicle features properly.
   • 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 ECU damage may occur.
   • Stable battery voltage is critical during programming. Any fluctuation, spiking, over voltage or loss of voltage will interrupt programming. Install the EL-49642 SPS Programming Support Tool to maintain system voltage. If not available, connect a fully charged 12 V jumper or booster pack disconnected from the AC voltage supply. DO NOT connect a battery charger.
   • Turn OFF or disable systems that may put a load on the vehicles battery such as; interior lights, exterior lights (including daytime running lights), HVAC, radio, etc.
   • During the programming procedure, follow the SPS prompts for the correct ignition switch position.
   • Clear DTCs after programming is complete. Clearing powertrain DTCs will set the Inspection/Maintenance (I/M) system status indicators to NO.

Replace and Program ECU

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:
    5. • 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 metres.

    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 Immobiliser Learn procedure was not properly completed. The Immobiliser 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 Immobiliser Learn is complete, press the Unlock button on the keyless entry transmitter to allow the keyless entry transmitter to exit the Immobiliser Learn mode.

    6. Note: When performing the Tyre Pressure Monitor Sensor Learn during BCM setup, the EL-46079 tyre pressure monitor diagnostic tool must be used to activate each tyre 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 centre display for additional messages regarding further calibration instructions. If there are no additional driver information centre instructions present, programming is complete.
  8. At the end of programming, choose the "Clear All DTCs" function on the SPS screen.

Reprogram ECU

To program an existing 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. Note: When performing the Tyre Pressure Monitor Sensor Learn during BCM setup, the EL-46079 tyre pressure monitor diagnostic tool must be used to activate each tyre pressure sensor.

  4. On the SPS Supported Controllers screen, select BCM Body Control Module - Setup and follow the on-screen instructions.
  5. Check the driver information centre display for additional messages regarding further calibration instructions. If there are no additional driver information centre instructions present, programming is complete.
  6. At the end of programming, choose the "Clear All DTCs" function on the SPS screen.

Unsuccessful Programming Recovery

In the event of an interrupted or unsuccessful programming event, perform the following steps:

  1. DO NOT turn the ignition OFF. Ensure that all ECU, DLC and programming tool connections are secure and the TIS terminal operating software is up to date.
  2. Attempt to reprogram the ECU.
  3. If the ECU can still not be programmed, turn the ignition OFF for at least one minute.
  4. Turn the ignition ON and attempt to reprogram the ECU. The ECU should program.
    5. ⇒If the ECU still cannot be programmed, replace the ECU.
