Diagnostic Fault Information

Circuit/System Description

The liftgate motor is a bi-directional motor and open or close operation is the result of the direction of the motor rotation. The liftgate control

module (LGM) controls the liftgate motor through the control circuits by supplying power and ground in the appropriate polarity. The motor

control circuits are monitored by the LGM prior to activation for a high or low condition and during motor operation for any irregular current flow

conditions.
