Circuit/System Testing

  1. Ignition ON.
  2. Perform the Service Programming System (SPS) . The K194 Rear Gate Module should learn the travel limits, exit the calibration mode, and B1C0A 54 will become a history code.
    • If the K194 Rear Gate Module does not exit the calibration mode or if B1C0A 54 does not become a history code. 

      Replace the K194 Rear Gate Module.

    • Go to next step: If the K194 Rear Gate Module does exit the calibration mode and B1C0A 54 becomes a history code. 
  3. All OK.
