Courtesy Lamps: Notes
WARNING: This page is about a different car, the 2011 Lincoln MKT. However, it is still accessible from the selected car via links, so may be relevant.
The courtesy lamps are controlled by the SJB. The courtesy lamp subsystem consists of the door ajar switches (integrated into the door latches), the LTM, the interior dome lamps, the footwell lamps, the RFA module, the instrument panel dimmer switch and the puddle lamps.
