Test 68B - Shorted Liftgate Circuit

NOTE: For connector terminal identification, see CONNECTOR IDENTIFICATION  . For appropriate wiring diagram, see WIRING DIAGRAMS  section at the end of this article. Perform TEST VER-1B after each repair.
CAUTION: Always turn ignition off prior to disconnecting or connecting any module connector.
  1. Remove liftgate release relay from relay block. Using scan tool in ohmmeter mode, check resistance of liftgate release relay connector (Light Green/Black wire). If resistance is less than 5 ohms, go to step 6). If resistance is more than 5 ohms, go to next step.
  2. Check resistance of liftgate release relay connector (Dark Green/Yellow wire). If resistance is more than 5 ohms, repair short to ground in Dark Green/Yellow wire. If resistance is less than 5 ohms, go to next step.
  3. Check resistance of liftgate release relay connector (Yellow/Black wire). If resistance is more than 5 ohms, replace liftgate release relay. If resistance is less than 5 ohms and vehicle is not equipped with Remote Keyless Entry (RKE), repair short to ground in Yellow/Black wire. If vehicle is equipped with RKE, go to next step.
    NOTE: RKE module may be accessed by carefully prying each end of instrument panel top cover and sliding cover forward to disengage front clips.
  4. Gain access to RKE module. RKE module is located under instrument panel top cover, behind information center. Disconnect RKE module connectors. Go to next step.
  5. Check resistance of liftgate release relay connector (Yellow/Black wire). If resistance is more than 5 ohms, replace RKE module. If resistance is less than 5 ohms, repair short to ground in Yellow/Black wire.
  6. Disconnect liftgate release solenoid connector. Check resistance of liftgate release relay connector (Yellow/Black wire). If resistance is more than 5 ohms, replace liftgate release solenoid. If resistance is less than 5 ohms, repair short to ground in Yellow/Black wire.
