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. The
power lock motor is integral to the door latch mounted within each door.
On models with a base version of the Central Timer Module (CTM), the power lock motor direction is controlled by the battery and ground feeds
from the power lock switches. On models with the high-line version of the CTM, 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 CTM.
The power lock motor cannot be repaired and, if faulty or damaged, the entire door latch unit must be replaced.
