Principles of Operation: Autolock
WARNING: This page is about a different car, the 2006 Mercury Mariner and 2006 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
The autolock feature locks all the doors when all the doors, including the liftgate, are closed, the brake pedal is pressed with the key in the ON position, and the vehicle speed exceeds 5 kph (3 mph). This feature relocks the doors (if any doors were open) after the brake pedal is pressed, once all the doors are read as closed and the vehicle speed exceeds 5 kph (3 mph). The door ajar switches are wired directly to the SJB. The autolock feature can be enabled/disabled through module configuration and the ignition cylinder methods.
