Checking The Wiring

Disconnect the connector at the switch for opening the tailgate. Check whether the switch has stuck in the activated position by taking a reading between terminals. Use an ohmmeter. The resistance must be infinite. If the resistance is 0 Ω - replace the switch.

Check the cable between the keyless vehicle module (KVM) and the tailgate switch.

Check the cable between the switch and ground. Check for an open-circuit. Check for a short-circuit to ground.

Remedy as necessary.
