FEM Operation
WARNING: This page is about a different car, the 2005 Lincoln LS. However, it is still accessible from the selected car via links, so may be relevant.
This system is unique in that many of the inputs the FEM receives are delivered via the SCP communication network. These input messages come from other modules connected to the network, such as the rear electronics module (REM), driver door module (DDM), and instrument cluster. The FEM interprets the inputs and, in turn, commands the correct output. The FEM also receives inputs which come directly from components hardwired to the module, such as the front door ajar switches.
