Power Door Lock Actuator: Description and Operation
SYSTEM OPERATION
In the power lock and Remote Keyless Entry (RKE) systems, the locks are actuated by a reversible motor mounted within each door and the
liftgate. The driver front door lock motor direction is controlled by the battery and ground feeds from the Driver Door Module (DDM). The
remaining door lock motors and the liftgate lock motor are controlled by the battery and ground feeds from the Passenger Door Module (PDM).
The power lock motor cannot be repaired and, if faulty or damaged, the entire motor must be replaced.
