Test 36C - Diagnosing Liftgate Release

NOTE: For connector terminal identification, see CONNECTOR IDENTIFICATION. For wiring diagrams, see WIRING DIAGRAMS article in the ENGINE PERFORMANCE Section. Perform TEST VER - 1A after each repair.
CAUTION: Always turn ignition switch to OFF position prior to disconnecting or connecting any module connector.
  1. Ensure jumper wire between Blue body controller connector terminal No. 18 (Brown/Light Blue wire) and ground is still connected. Using DRB-II in voltmeter mode, measure voltage of output circuit at liftgate switch side of fuse No. 4 (Light Green/Black wire). While measuring voltage, press liftgate switch.
  2. If voltage is less than 10 volts, replace liftgate switch. If voltage is more than 10 volts, remove fuse No. 4. If fuse is okay, go to step 4). If fuse is blown, disconnect liftgate solenoid connector.
  3. Using DRB-II in ohmmeter mode, measure resistance of fused output circuit at solenoid side of fuse No. 4. If resistance is less than 5 ohms, repair short to ground in Light Green/Black wire and replace fuse No. 4. If resistance is more than 5 ohms, replace liftgate solenoid and fuse No. 4.
  4. Reinstall fuse No. 4 and disconnect liftgate solenoid connector. Using DRB-II in voltmeter mode, measure voltage of output circuit at liftgate solenoid connector (Light Green/Black wire).
  5. While measuring voltage, press liftgate switch. If voltage is less than 10 volts, repair open Light Green/Black wire. If voltage is more than 10 volts, replace liftgate solenoid.
