Section 139 (Power Liftgate System): Latch: Operation
WARNING: This page is about a different car, the 2005 Dodge Grand Caravan, 2005 Dodge Caravan, and 2005 Chrysler Town & Country. However, it is still accessible from the selected car via links, so may be relevant.
On the power cinch/release latch, the latch mounted actuator provides the torque required to close the power liftgate from the secondary to the primary closed and latched position. On the power cinch/release latch and the power release only latch, the actuator releases the liftgate from the primary closed and latched position to the fully unlatched and movable position.
