Trunk / Liftgate Motor: Description and Operation
Power Liftgate Drive Unit - Description
DESCRIPTION
Vehicles equipped with a power liftgate system, utilize a power liftgate drive unit (3). The drive unit assembly consists of a DC motor, gear position
sensor, clutch, full-open switch, housing/bracket assembly and wire harness. The clutch and motor portion of the assembly provides the power and torque
required to open or close the liftgate (5) under most conditions. The Hall Effect position sensor is used to provide the liftgate control module with a
clutch/motor speed signal. This speed signal is used to monitor any resistance of liftgate travel and allows the liftgate control module to detect
obstructions and control the liftgate accordingly. The clutch assembly is used to allow automatic power open/close mode and full manual operation, if
desired. The full-open switch is used to let the liftgate control module know when the liftgate is approaching the full open position.
The drive unit (3) is secured to the D-pillar (1) with three retaining bolts (4). The drive unit (3) is connected the liftgate (5) with the link rod (6).
The drive unit cannot be adjusted or repaired and if damaged or inoperative must be replaced. See: Service and Repair/Power Liftgate Drive Unit -
Removal for the appropriate procedure.
