POWER LIFTGATE RELEASE SYSTEM
Check fuse No. 8 in junction block. Junction block is located on steering column support bracket. If fuse is okay, reinstall fuse and go to next step. If fuse is blown, use wiring diagram as a guide to check for cause of blown fuse and repair as necessary. See WIRING DIAGRAMS. Replace fuse and recheck system operation.
Using a voltmeter, measure voltage between ground and fuse No. 8 connector, B+ circuit terminal (Pink/White wire). If battery voltage is not present, repair open B+ circuit between Power Distribution Center (PDC) and junction block. If battery voltage is present, go to next step.
Remove liftgate trim panel. See LIFTGATE TRIM PANEL under REMOVAL & INSTALLATION. Disconnect liftgate flip-up push button switch 2-pin connector. Using voltmeter, check voltage between ground and liftgate flip-up push button switch 2-pin connector terminal No. 2, fused B+ circuit (Pink wire). If battery voltage is not present, repair open B+ circuit between junction block and liftgate flip-up push button switch 2-pin connector. If battery voltage is present, reconnect liftgate flip-up push button switch 2-pin connector and go to next step.
Press liftgate flip-up push button switch. Using voltmeter connected to ground, backprobe liftgate flip-up push button switch 2-pin connector terminal No. 1, liftgate flip-up push button switch output circuit (Orange/Pink wire). If voltage is not present, replace liftgate flip-up push button switch. If voltage is present, leave liftgate flip-up push button switch pressed and go to next step.
Disconnect liftgate lock motor connector. Liftgate lock motor is integral to liftgate latch mechanism. Using a voltmeter, check voltage between ground and liftgate lock motor connector terminal No. 3, liftgate flip-up push button switch output circuit (Orange/Pink wire). See Fig. 1. If battery voltage is not present, repair open liftgate flip-up push button switch output circuit. If battery voltage is present, release liftgate flip-up push button switch and go to next step.
