Multifunction Electronic Control Module: Description and 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. Often times, erratic or
unexpected GEM function can be traced to problems with these GEM inputs.
The GEM controls the following features:
^ Wipers/washers (front/rear).
^ Warning chimes.
^ Battery saver.
^ Illuminated entry and courtesy lamps.
Page 76
^ Driver power window.
^ Accessory delay.
^ 4-wheel drive.

There are four modes of operation for the front wipers: speed dependent interval, slow, fast and
wash. These modes are only active with the ignition switch in the RUN or ACC position.
The two modes of operation for the rear wipers are interval and wash. These modes are only active
with the ignition switch in the RUN or ACC positions and with both the liftgate and liftgate glass
closed.
The GEM controls five warning chimes and lamps: headlamps operating without the ignition on
(chime only), door ajar (chime and lamp), key-in-ignition (chime only), driver seat safety belt
warning (chime and lamp), and low washer fluid warning (chime and lamp).
The battery saver feature removes extended interior lamp power drains from the battery. The GEM
will keep power available for all interior lights and under hood lamp circuits for 40 minutes after the
ignition switch is turned off.
The GEM illuminates the interior courtesy lamps when any door is ajar. The GEM also provides
illuminated entry when the unlock button is used to unlock the vehicle.
The GEM illuminates the running board lamps when the interior lamps are activated (see courtesy
lamps and illuminated entry description above) and the ignition switch is not in the RUN position.
The delayed accessory feature provides power to the power windows for ten minutes after the
ignition switch is moved from the RUN to the OFF position. If during this ten-minute period either
front door is opened, the delayed accessory relay will be de-energized.
This system is equipped with Automatic 4-Wheel Drive (A4WD).
