Module Controlled Functions

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.

NOTE: Prior to removal of the generic electronic module (GEM), it is necessary to upload module configuration information to the diagnostic tool.

This information needs to be downloaded into the new module once installed. For additional information, refer to MODULE CONFIGURATION .

NOTE: Electronic modules are sensitive to electrical charges. If exposed to these charges, damages may result.

The generic electronic module (GEM) is the only multi-function module on this vehicle.

The GEM constantly monitors its subsystems for concerns. If a concern is found in one of the subsystems, the GEM will record the concern in the form of a diagnostic trouble code (DTC).

The ignition switch position is very important to the GEM functionality Erratic or unexpected GEM functions can often be traced to problems with these GEM inputs.

The GEM controls a variety of systems:

instrument cluster warning indication and chimes
interior courtesy lamp control
automatic headlamp control
daytime running lamps (DRL)
wiper and washer (front only)
heated rear window
one-touch down power window
delayed accessory
power door locks (including SMART, autolocking and luggage compartment lid release)
remote keyless entry
perimeter anti-theft
