Unlatch/Cinching Motor

The latch uses a bi-directional motor to accomplish both unlatch and cinch operations. The motor is driven in one direction to cinch and in the opposite direction to unlatch.

During a cinch operation, power is supplied to the unlatch/cinching motor by the LTM when the secondary latch position is reached during a power close operation. When the motor activates, it pulls the liftgate into the primary latch position. The LTM removes power from the unlatch/cinching motor when the primary latch position is reached.

During an unlatch operation, power is supplied to the unlatch/cinching motor by the LTM when a valid open command is received.
