Principles of Operation
WARNING: This page is about a different car, the 2003 Ford Windstar. However, it is still accessible from the selected car via links, so may be relevant.
The Windstar's electronic functions are divided into zones. The front electronic module (FEM) controls the front portion of the vehicle and the rear electronic module (REM) controls the rear portion of the vehicle. These systems rely heavily on the standard corporate protocol (SCP) communication network in order to transmit and receive signals.
The FEM controls the following systems:
- wiper, washer (front and rear)
- warning chime
- accessory delay
- switched system power (relay 1 and 2 of 4 relays)
- driver one-touch power window
- front blower motor relay
- front parking lamps
- cornering lamps
- front headlamps
- front turn signal lamps
- front door locks
