WARNING: This page is about a different car, the 2007 Lincoln MKX and 2007 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.
The interior lighting system consists of the following components:
- Smart junction box (SJB)
- Power liftgate module (if equipped)
- Dimmer control switch
- Interior/map lamps
- Cargo lamp
- Vanity mirror lamps
- Door ajar switches
The interior lighting system consists of 2 subsystems:
- Courtesy lamps
- Demand lamps
The courtesy lamps are controlled by the SJB. The SJB supplies voltage to the courtesy lamps. The courtesy lamp subsystem consists of the interior dome lamps, the overhead console lamps (if equipped), the cargo lamp, and the puddle lamps (if equipped).
The SJB supplies voltage to the demand lamps. The demand lamps subsystem consists of the front map lamps, and the left and right vanity mirror lamps.
The SJB supplies power to the interior lighting system. The SJB and the power liftgate module (if equipped) set DTCs if certain circuit failures exist with the interior lighting system.
