Test B: The Power Liftgate Is Inoperative From An Individual Switch
PINPOINT TEST B: THE POWER LIFTGATE IS INOPERATIVE FROM AN INDIVIDUAL SWITCHNormal Operation
If the power liftgate (PLG) is operated from the PLG control switch (instrument panel), circuit CPR63 (GY/YE) is grounded by the open/close switch, which signals the PLG module of the open/close request. If the PLG is operated from the rear switch (quarter trim panel), circuit CPR63 (GY/YE) is grounded by the rear switch through circuit GD148 (BK/YE). If the PLG is operated from the liftgate handle, the smart junction box (SJB) sends a voltage signal to the PLG module through circuit CPL10 (GN/WH).
