Power Door Lock Actuator: Description and Operation
In the power lock and Remote Keyless Entry (RKE) systems, the door and liftgate 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. A separate power lock motor is used to actuate the liftgate latch.
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 RKE receiver within the CTM can also unlock just the driver door through a separate driver door unlock relay that is
located in the relay and fuse block attached to the back of the junction block under the instrument panel.
The power door lock motors cannot be repaired and, if faulty or damaged, the entire door latch unit must be replaced. The power liftgate lock motor is
serviced separately.
