Replace and Program Control Module

To program a replacement K9 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.
   NOTE:

   Make sure the vehicle ignition switch state is in appropriate position for the following step.

   • 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.
3. On the SPS Supported Controllers screen, select K9 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 m.
   • Push Button Start System: Keyless entry transmitter must be in the programming pocket. Refer to the owner manual for the exact pocket location. All additional transmitters must be away from the vehicle at least 3 m.
5. 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.
   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.
6. 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.
   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 for vehicles with UJM.

   • 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.
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 DTCs" function on the SPS screen.
9. If ABS, Traction Control and/or Stabilitrak indicators are ON and DTC C0161 is set in the K17 Electronic Brake Control Module after performing BCM programming and setup, do the following:
   1. Disconnect the scan tool from the X84 Data Link Connector.
   2. 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 2 min to power down.
   3. 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.
   4. Use the scan tool to clear the DTCs.
