Principles of Operation
The power liftgate is controlled by the power liftgate module.
The power liftgate module receives inputs from:
- glass position switch (determines the ajar status of the liftgate glass).
- forkbolt switch (determines the primary position of the latch).
- detent switch (determines the secondary position of the latch).
- home switch (determines the power cinch status).
- power liftgate control switch (activates the power liftgate from the interior of vehicle).
- pinch strip switches (determines if an obstacle is detected between the pinch strip and liftgate).
- instrument cluster module (activates and sets the options for the power liftgate).
- optical sensor (determines the direction, travel speed and obstacle detection of the liftgate).
- UBP serial communication link.
The power liftgate module sends outputs to:
- liftgate motors.
- power cinching latch system.
- liftgate chime module.
- body security module
