Generic Electronic Module (GEM)
WARNING: This page is about a different car, the 2003 Mercury Sable and 2003 Ford Taurus. However, it is still accessible from the selected car via links, so may be relevant.
The generic electronic module (GEM) receives inputs from the following:
- door ajar switches
- liftgate ajar switch (wagon)
- liftgate glass switch (wagon)
- headlamp switch
- keyless entry keypad switches
- the powertrain control module (PCM) (vehicle speed signal)
- ignition switch
- remote keyless entry transmitter
The GEM uses these inputs to control the output to the battery saver relay and interior lamp relay. Both relays are integral to the central junction box (CJB) and cannot be accessed directly.
