Multifunction Electronic Control Modules: Description and Operation
Principles of Operation (How Does It Work?)
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 functionality. Erratic or unexpected GEM functions can often be traced to problems with these
GEM inputs.
The GEM controls a variety of systems:
^
windshield wipers
^
courtesy lamps
^
warning chimes
^
keyless entry
^
interior and exterior lamps
^
power windows
