Tests AB: The Power Liftgate Operates From The Rear Switch Or Handle With The Overhead Console Switch In The Off Position
PINPOINT TEST AB: THE POWER LIFTGATE OPERATES FROM THE REAR SWITCH OR HANDLE WITH THE OVERHEAD CONSOLE SWITCH IN THE OFF POSITIONAB1-AB2:
AB2-AB3:
Normal Operation
If the power liftgate is operated from the overhead console open/close switch, circuit 2054 (YE) is grounded by the open/close switch. Then the SJB grounds circuit 700 (WH/VT) which signals the PLG module of the open/close request.
If the power liftgate is in the CLOSED position and the conditions are correct, the PLG module supplies 12 volts to the unlatch actuator on circuit 2058 (LB/RD) and 12 volts to the clutch on circuit 2062 (LG/RD) and 12 volts to the motor on circuit 2060 (RD/BK). As the liftgate is moving in the open direction, the PLG module monitors the position sensor for obstacles.
If the power liftgate is in the OPEN position and the conditions are correct, the PLG module supplies 12 volts to the clutch on circuit 2062 (LG/RD) and 12 volts to the motor on circuit 2061 (VT/WH). As the liftgate is moving in the close direction, the PLG module monitors the position sensor and the pinch strips for obstacles.
Possible Causes
- circuit 1236 (VT/WH) short to ground
- overhead console on/off switch
- PLG module
