Replace and Program Control Module
To program a replacement K9 Body Control Module (BCM), perform the following procedure:
- For Key Ignition System, begin with the ignition in the RUN position.
- For Push Button Start System, begin with the vehicle in vehicle OFF power mode. The Service Programming System will power mode the vehicle.
- Access the Service Programming System (SPS) and follow the on-screen instructions.
- On the SPS Supported Controllers screen, select K9 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 m (9.8 ft).
- Push Button Start System: Keyless entry transmitter must be in the programming pocket. Refer to the Remote Keyless Entry (RKE) System Operation document located the Keys, Doors, and Windows > Keys and Locks category in the Owner's Manual for the exact pocket location. All additional transmitters must be away from the vehicle at least 3 m (9.8 ft).
- On the SPS Supported Controllers screen, select Z1 Immobilizer Learn. 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.
- For Key Ignition System, begin with the ignition in the RUN position.
- For Push Button Start System, begin with the vehicle in vehicle ON power mode.
- On the SPS Supported Controllers screen, select K9 Body Control Module - Setup (or K9 Body Control Module - Configuration & 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.
- Clear DTCs.
- If ABS, Traction Control and/or Stabilitrak indicators are ON and DTC C0161 is set in the K17 Electronic Brake Control Module after performing K9 Body Control Module programming and setup, do the following:
- Disconnect the scan tool from the X84 Data Link Connector.
- Ignition/Vehicle OFF, all access doors closed, all vehicle systems OFF, and all keys at least 3 m (9.8 ft) away from the vehicle. It may take up to 10 min to power down.
- Ignition ON/Vehicle In Service Mode, 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.
Make sure the vehicle ignition switch state is in appropriate position for the following step.
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 for vehicles with UJM.
