Power Door Lock Actuator: Description and Operation
Models equipped with the optional power lock system have a power operated locking mechanism located within each door. The lock mechanisms are
actuated by a reversible electric power lock motor. This motor is integral to the door latch unit within each door. A single short pigtail wire with a
molded plastic connector insulator connects each lock motor to the vehicle electrical system through a take out and connector of the wire harness within
each door.
The power lock motors cannot be adjusted or repaired and, if faulty or damaged, the entire door latch unit must be replaced.
The driver side front door power lock motor is controlled by a unique driver unlock relay output of the Central Timer Module (CTM), while the
remaining power lock motors are all connected in parallel and share common CTM lock and unlock relay outputs. The driver side front door power lock
motor also shares the common lock relay output from the CTM. This circuit arrangement makes the Remote Keyless Entry (RKE) system driver door
unlock only feature option for these models possible. A positive and negative battery connection to the two power lock motor terminals will cause the
power lock motor plunger to move in one direction. Reversing the current through these same two connections will cause the power lock motor plunger
to move in the opposite direction. The power lock motors and circuits can be tested using conventional diagnostic tools and methods.
