Principles of Operation: Autolock

WARNING: This page is about a different car, the 2005 Ford Pickup. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: The autolock feature is not available on vehicles equipped with manual transmissions.

The autolock feature locks all the doors when all the doors are closed, the brake pedal is pressed with the key in the ON position, and vehicle speed then exceeds 8 km/h (5 mph) or higher. 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 vehicle speed then exceeds 8 km/h (5 mph). Door ajar switches are wired directly to the vehicle security module. The autolock feature can be enabled/disabled through module configuration, the ignition switch, and the RKE keypad. The auto-lock feature also uses inputs from the key position, the brake pedal position (BPP) switch, and vehicle speed through the universal asynchronous receiver-transmitter (UART)-based protocol (UBP) network.
