Principles of Operation

The generic electronic module (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 function. Erratic or unexpected GEM function can often be traced to problems with these GEM inputs.

The GEM controls a variety of systems:
- interval rear window wiper
- battery saver
- illuminated entry
- headlamp control
- interior lamp control
- power door locks
- remote keyless entry (RKE)
- accessory delay
- door ajar output control
