Principles of Operation

WARNING: This page is about a different car, the 2008 Ford RV Cutaway, 2008 Ford Econoline, 2008 Ford E450 Super Duty, and 2008 Ford Cutaway. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: For vehicles equipped with E-Guard Cargo Protection System^TM , the side and rear cargo doors will not unlock electronically or from the interior door lock rod.

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 will then actuate to a lock or unlock position determined by the voltage on the lock or unlock circuit.
