Test H: The Power Liftgate Does Not Power Open (Power Close OK)
PINPOINT TEST H: THE POWER LIFTGATE DOES NOT POWER OPEN (POWER CLOSE OK)Normal Operation
If the power liftgate (PLG) is in the closed position and the conditions are correct, the PLG module supplies 12 volts to the unlatch/cinching motor on circuit CPR62 (WH/BU), 12 volts to the clutch on circuit CPR69 (BN/BU) and 12 volts to the motor on circuit CPR57 (GN/WH). As the liftgate is moving in the open direction, the PLG module monitors the position sensor for door speed to detect obstacles. Once the liftgate is unlatched, the motor and clutch are activated to power open the liftgate.
This pinpoint test is intended to diagnose the following:
- PLG latch
- PLG sector gear switches
- PLG module
- Wiring, terminals or connectors
