Cinching Motor
WARNING: This page is about a different car, the 2018 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.
The cinching motor is driven in one direction to cinch the liftgate and in the opposite direction to its start position.
During a cinch operation, power is supplied to the cinching motor by the RGTM 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. When the fully latched position is reached, the RGTM reverses the polarity to the cinching motor until it reaches its start position.
