Principles Of Operation: Auto-Unlock
WARNING: This page is about a different car, the 2006 Mercury Grand Marquis and 2006 Ford Crown Victoria. However, it is still accessible from the selected car via links, so may be relevant.
The driver door module (DDM) energizes the unlock relay based on input from the door ajar switches and the vehicle speed signal. The DDM unlocks the doors when the following conditions are met:
- The vehicle speed has exceeded 5 km/h (3 mph) then dropped to 0 km/h (0 mph) (vehicle stopped).
- The key is turned to the OFF or ACCY position.
- The LH front door is opened within 10 minutes of the key being turned to the OFF or ACCY position.
The auto unlock feature is cancelled if the doors are locked with the door lock control switch or the remote keyless entry (RKE) transmitter within the 10 minute active window. After the 10-minute active window expires the auto-unlock feature does not unlock the doors if the driver door is opened.
