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.
