Trunk / Liftgate: Testing and Inspection
1. Check the fuse in the junction block. If OK, go to Step 2. If not OK, repair the shorted circuit or component as required and replace the faulty fuse.
2. Check for battery voltage at the fuse in the junction block. If OK, go to Step 3. If not OK, repair the open circuit as required.
3. Unplug the liftglass limit switch wire harness connector. Check for battery voltage at the fused B(+) circuit cavity of the limit switch wire harness
connector. If OK, go to Step 4. If not OK, repair the open circuit as required.
4. Check for continuity between the two terminals of the liftglass limit switch. There should be continuity with the liftgate latch unlocked, and no
continuity with the latch locked. If OK, go to Step 5. If not OK, replace the faulty limit switch.
5. Unplug the liftglass push button switch wire harness connector. With the liftgate latch unlocked, check for battery voltage at the liftglass limit
switch output circuit cavity of the push button switch wire harness connector. If OK, go to Step 6. If not OK, repair the open circuit as required.
6. Check for continuity between the two terminals of the liftglass push button switch. There should be no continuity. Depress the switch, there should
now be continuity. If OK, go to Step 7. If not OK, replace the faulty push button switch.
7. Unplug the liftglass release solenoid wire harness connector. Check for continuity between the ground circuit cavity of the wire harness connector
and a good ground. There should be continuity If OK, go to Step 8. If not OK, repair the open circuit as required.
8. With the liftgate latch unlocked and the lift-glass push button switch depressed, check for battery voltage at the liftglass push button output circuit
cavity of the liftglass release solenoid wire harness connector. If OK, replace the faulty solenoid. If not OK, repair the open circuit as required.
