Reversing Lamps
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 reversing lamps are controlled by the SJB and the powertrain control module (PCM). The PCM sends a message through the communication network indicating the transmission is in REVERSE. The SJB processes this information and provides voltage to the reversing lamps which are hard-wired to the SJB.
