Power Door Lock Switch: Description and Operation

The power lock system is controlled by a two-way switch that is integral to the Driver Door Module (DDM) and the Passenger Door Module (PDM), mounted in the trim panel of its respective front door. Each switch is illuminated by a light-emitting diode when the ignition switch is turned to the ON position.

The power lock switches and their lamps cannot be repaired. If the switches are damaged or faulty, the entire PDM or DDM unit must be replaced.

The power lock switches provide a hard wired Lock and/or Unlock signal to the power lock system control circuitry, which is located within the Passenger Door Module (PDM).
