Circuit/System Testing

  1. Ignition ON.
  2. Perform the Liftgate Calibration . The K39 Liftgate Control Module should learn the travel limits, exit the calibration mode, and B1019 00 will become a history code.
    • If the K39 Liftgate Control Module does not exit the calibration mode or if B1019 00 does not become a history code. 

      Replace the K39 Liftgate Control Module

    • Go to next step: If the K39 Liftgate Control Module does exit the calibration mode and B1019 00 becomes a history code. 
  3. All OK.
