Exterior Lighting: Autolamps

WARNING: This page is about a different car, the 2005 Mercury Montego, 2005 Ford Freestyle, and 2005 Ford Five Hundred. However, it is still accessible from the selected car via links, so may be relevant.

The autolamps are controlled by the headlamp switch, light sensor and the SJB. When the headlamp switch is in the AUTOLAMPS ON position, the SJB monitors input from the light sensor. The SJB processes this information and outputs the appropriate command to the exterior lamps. The autolamps remain on for a preselected amount of time (approximately 20 seconds to 3 minutes depending on customer preferences) after the ignition switch is changed from the ON position to the ACC or OFF position.

The exit time delay is programmed in the following sequence.

NOTE: Steps 2 through 5 must be carried out within a 10-second period.

Make sure the ignition switch is turned OFF and the headlamp switch is in the AUTOLAMPS ON position.
Place the headlamp switch to the OFF position.
Turn the ignition switch to the RUN position.
Turn the ignition switch to the OFF position.
Place the headlamp switch to the AUTOLAMPS ON position (at this time the headlamps and parking lamps illuminate).
When the desired length of time is reached (maximum of 3 minutes), place the headlamp switch to the OFF position.
