GS Drive Unit Components
Vehicles equipped with a power liftgate, utilize a power liftgate drive unit. The drive unit assembly consists of a DC motor, optical sensor, clutch,
full-open switch, rack, 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 under the worst case conditions. The optical sensor is used to provide the lift-gate 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/or full manual operation, if desired. The full-open
switch is used to let the lift-gate control module know when the liftgate is approaching the full open position.
