Principles of Operation

WARNING: This page is about a different car, the 2007 Ford Pickup, 2007 Ford F550 Super Duty, 2007 Ford F450 Super Duty, and 2007 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.

Regardless of the key position, the door lock control switches are powered at all times. The door lock control switches supply voltage to either the lock or unlock circuit based upon the switch position. The door lock actuators then actuate to a lock or unlock position determined by the voltage on the lock or unlock circuit.
