Automatic Transaxle
WARNING: This page is about a different car, the 2009 Mercury Milan, 2009 Lincoln MKZ, and 2009 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
The SJB receives a message from the transmission control module (TCM) when the transaxle is in REVERSE (R).
When the transaxle is placed in REVERSE (R), the SJB provides a ground for the reversing lamp relay coil (internal to the SJB). The reversing lamps receive voltage when the reversing lamp relay is energized. The reversing lamps are located within the rear lamp assemblies (Fusion), or the decklid (Milan and MKZ).
