Reprogram Control Module

To program an existing K9 Body Control Module, perform the following procedure:

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 ON power mode.
1. Access the Service Programming System (SPS) and follow the on-screen instructions.
2. On the SPS Supported Controllers screen, select K9 Body Control Module - Programming 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.

3. 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.
4. 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.
5. At the end of programming, choose the "Clear DTCs" function on the SPS screen.
6. 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 10 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.
