Power Door Lock Actuator: Description and Operation

In the power lock and Remote Keyless Entry (RKE) systems, the door latch lock mechanisms can be actuated by a reversible electric motor. The power lock motor is integral to the door latch mounted within each door. The power lock motor direction is controlled by the battery and ground feeds from the power lock and unlock relays, which are integral to the high-line Central Timer Module (CTM).

The power lock motor cannot be repaired and, if faulty or damaged, the entire door latch unit must be replaced.
