The power lock system allows all of the doors to be locked or unlocked electrically by operating a switch on either front door trim panel. When an actuation input signal from the door lock switch, WIN or FOBIK signal is received, the door modules turns on the output drivers a provides a voltage level to the door lock motor for a specified time to lock/unlock the door. Their are two door modules, the Driver Door Module (DDM) and Passenger Door Module (PDM). The door modules have an unswitched battery feed from the TIPM, so the locks can be actuated in any ignition switch position.

The door modules locks the doors automatically when the vehicle is driven beyond the speed of 25.7 km/h (15 mph), all doors are closed and the accelerator pedal is depressed. The rolling door lock feature can be disabled if desired.

This vehicle also offers several customer programmable features, which allows the selection of several optional electronic features to suit individual preferences.

The power lock system for this vehicle can also be operated remotely using the FOBIK.

Certain functions and features of the power lock system rely upon resources shared with other electronic modules in the vehicle over the CAN data bus network. For proper diagnosis of these electronic modules or of the CAN data bus network, the use of a scan tool and the appropriate diagnostic information are required.
