Cinching/Unlatching Motor
WARNING: This page is about a different car, the 2021 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.
The unlatch motor is only driven in one direction to unlatch the tailgate, similar to an actuator cinching. The motor is driven in the opposite direction to return to the home 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 tailgate 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 home position.
