Programming an Existing Control Module

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

NOTE:
  • Verify all control modules are connected and communicating before attempting to program the control module.
  • Begin with the vehicle in vehicle OFF power mode. The Service Programming System will power mode the vehicle.
  1. Ignition/Vehicle OFF, ensure that the key fob is inside the vehicle and not moved for the duration of the programming to prevent an inadvertent power mode change during programming.
  2. Disconnect Wi-Fi dongle if it is currently connected to EL-52100 (MDI 2). Install EL-52100 (MDI 2) using wired USB Connection from MDI 2 to computer/laptop and verify it is working properly. Using the EL-47955 (MDI) will result in a programming failure.
  3. Install an approved battery maintainer or power supply that provides a steady and stable voltage to support the 12V system during SPS programming events.
  4. Access the Service Programming System (SPS) and follow the on-screen instructions.
  5. On the SPS Supported Controllers screen, select K9 Body Control Module - Programming and follow the on-screen instructions.
  6. 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.
  7. Clear DTCs.
