Circuit/System Description
The latch motor is a bi-directional motor and cinch or unlatch operation is the result of the direction of the motor rotation. The liftgate module
(LGM) controls the latch 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 an insufficient current flow condition.
