Interior Lighting

WARNING: This page is about a different car, the 2006 Mercury Montego, 2006 Ford Freestyle, and 2006 Ford Five Hundred. However, it is still accessible from the selected car via links, so may be relevant.

The interior lighting system consists of two subsystems:

The interior lamps subsystem consists of the puddle lamps, overhead console, second row, third row (if equipped) dome lamps and luggage compartment lamp (if equipped). The smart junction box (SJB) provides the power circuit for the interior courtesy lamps.

The demand lamps subsystem consists of the overhead console, second row, third row (if equipped) dome lamps and the LH and RH vanity mirror lamps. Each of these lamps are switched individually and share a common ground circuit.

On vehicles equipped with autolamps, the illuminated entry feature does not turn the interior lamps on if the SJB determines it is daytime based on input from the light sensor.
