Circuit/System Testing

  1. Ignition ON.

    • 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

    • If the K39 Liftgate Control Module does exit the calibration mode and B1019 00 becomes a history code.
