Description & Operation: Notes

NOTE: On some vehicles, the power door lock system is integrated with the Remote Keyless Entry (RKE) system. For information on RKE, see KEYLESS ENTRY SYSTEMS article.

The power door lock system incorporates door lock switches on both front doors and on the right hand D-pillar, door lock motors in all passenger doors and in the right rear cargo door, a door lock relay and a door lock control module. When door lock switch is operated, all doors will lock or unlock. Each lock can also be operated manually. Locks are operated by reversible motors. Door lock switches operate to turn motors on by supplying battery voltage to one terminal and ground to the other terminal.

When either door lock switch is moved to LOCK position, switch completes a circuit to the motors. Motor in each door runs to operate door locks. When door lock switch is released, circuit is opened and motors turn off. When door lock switch is moved to UNLOCK position, polarity of voltage to motors is reversed.
