Power Locks

WARNING: This page is about a different car, the 2002 Jeep Liberty. However, it is still accessible from the selected car via links, so may be relevant.

The power lock system allows all of the doors and the tailgate to be locked or unlocked electrically by operating a switch on either front door trim panel. The power lock system receives non-switched battery current through a fuse in the Junction Block (JB), so that the power locks remain operational, regardless of the ignition switch position. The Body Control Module (BCM) locks the doors and tailgate automatically when the vehicle is driven at speeds of 15 MPH (25.7 KM/H) or more, 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 available Remote Keyless Entry (RKE) system radio frequency transmitters, if equipped. Certain functions and features of the power lock system rely upon resources shared with other electronic modules in the vehicle over the Programmable Communications Interface (PCI) data bus network. For proper diagnosis of these electronic modules or of the PCI data bus network, the use of a DRBIII® scan tool and the appropriate diagnostic information are required.
