Test B: The Power Liftgate Is Inoperative From An Individual Switch

PINPOINT TEST B: THE POWER LIFTGATE IS INOPERATIVE FROM AN INDIVIDUAL SWITCH

Normal Operation
If the power liftgate is operated from the power liftgate control switch (instrument panel), circuit CPR63 (GY/YE) is grounded by the open/close switch, which signals the liftgate/trunk module (LTM) of the open/close request. If the power liftgate is operated from the rear switch (quarter trim panel), circuit CPR70 (GN) is grounded by the rear switch through circuit GD149 (BK/GY). If the power liftgate is operated from the liftgate handle, the smart junction box (SJB) sends a voltage signal to the LTM through circuit CPL10 (GN/WH).







This pinpoint test is intended to diagnose the following:
- Power liftgate control switch (instrument panel)
- Power liftgate rear control switch (quarter trim panel)
- LTM
- SJB
- Wiring, terminals or connectors
