Grand Cherokee 2WD V8-5.2L VIN Y (1998)
Driver/Vehicle Information Display: Description and Operation
Graphic Display Module
A Graphic Display Module (GDM) is standard equipment on all four-wheel drive Grand Cherokee models, unless the vehicle is equipped with the
optional Vehicle Information Center (VIC). The GDM is mounted in the lower center stack area of the instrument panel, above the ash receiver and
below the climate controls. Two-wheel drive Grand Cherokee models have a storage bin installed in place of the GDM as standard equipment.
The GDM display consists of a back-lit screen with a vehicle outline. The two rear wheels of the vehicle are illuminated by a lamp when the transfer case
is engaged in any two-wheel drive operating mode. The two front wheels are also illuminated when the transfer case is engaged in any four-wheel drive
operating mode.
The GDM also has up to three indicator lamps, which indicate whether the four-wheel drive mode selected is Lo, Part-Time, or Full-Time. The number
of operational indicator lamps may vary, depending upon the optional four-wheel drive transfer case in the vehicle. A switch on the transfer case is
hard-wired to the GDM to illuminate the proper wheels and indicator lamps.
The GDM bulbs and the transfer case switch can be serviced. However, if any other part of the GDM is damaged or faulty, the entire GDM must be
replaced.
