Principles of Operation
WARNING: This page is about a different car, the 2002 Ford Ranger. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Upon installation of a new generic electronic module (GEM), the module must be reconfigured. Refer to MODULE CONFIGURATION
prior to GEM removal.
The GEM receives inputs and delivers outputs to a majority of the electronically-controlled features of the vehicle. The GEM constantly monitors the systems under its control and reports a concern in the form of a diagnostic trouble code (DTC). The DTC can be retrieved with a diagnostic tool through the ISO 9141 communication network. The GEM controls the following features:
- front wiper and washer
- warning chime
- battery saver
- illuminated entry and interior lighting
- driver one-touch down power window (optional)
- battery saver relay
- door ajar warning indicator lamp
- safety belt warning indicator lamp
