• Ignition off.

  Disconnect the connector at the switch for opening the tailgate. Check whether the switch has stuck in the activated position by taking a reading using an ohmmeter between terminals #A1 and #A3. If the switch is defective: replace switch.

  Check the connection between the switch for opening the tailgate and central electronic module (CEM) terminal #F22 (#22). Check for a short-circuit to ground. Also check the cable between the switch and ground. Check for an open-circuit.

  Remedy the cables as necessary
