Power Door Lock Actuator: Description and Operation

SYSTEM OPERATION
In the power lock and Remote Keyless Entry (RKE) systems, the door latch lock mechanisms can be actuated by a reversible electric motor. A power lock motor module is secured to the bottom of the door latch mounted within each front door. A power lock motor is integral to the latches used on dual side or rear doors. A separate power lock motor with a connecting link is used to actuate the latch in the sliding side or single rear door.

The power lock motor direction is controlled by the battery and ground feeds from the power lock and unlock relays. The power lock and unlock relays are integral to the power lock and Remote Keyless Entry (RKE) module, or the Central Timer Module (CTM).

The power door lock motors cannot be repaired and, if faulty or damaged, they must be replaced. On dual side or rear doors the entire door latch unit must be replaced. The front door, sliding side door, and single rear door power lock motors are serviced separately.
