Solar Sensor: Description and Operation
CS Power Liftgate Optical Sensor
Vehicles equipped with a power liftgate utilize a optical sensor. This sensor is located on the drive unit clutch housing and is used to supply the power
liftgate control module with the motor/clutch speed. This speed signal helps the control module detect obstacles in the power liftgates path or liftgate
system component failure. Four wires connect the optical sensor to the drive unit's main electrical connector.
The optical sensor cannot be adjusted or repaired and if found to be faulty, must be replaced. Consult your Mopar parts catalog for a specific part
number.
The optical sensor provides a speed/time signal to the power liftgate control module. The speed signal is generated from a trigger wheel, located inside
the clutch housing of the drive unit assembly. When the optical sensor is installed in the clutch housing properly, the trigger wheel is positioned in the
optical sensor. Hard-wired inputs to and from the liftgate control module are used to monitor the speed/time of the liftgate motor and clutch assembly.
