Power Door Lock Actuator: Description and Operation

In the power lock and Remote Keyless Entry (RKE) systems, the door and liftgate locks are each actuated by a dedicated reversible electric motor mounted within each door and the liftgate. The power lock motor direction is controlled by the battery and ground feeds from the power lock and unlock relays integral to the Passenger Door Module (PDM).

The power lock motors in the doors cannot be repaired and, if faulty or damaged, the entire door latch must be replaced. The power lock motor for the liftgate is available for service separate from the lift- gate latch.

The power lock motor direction is controlled by the battery and ground feeds from the power lock and unlock relays integral to the Passenger Door Module (PDM).
