Grand Cherokee 2WD L6-4.0L VIN S (1997)
Driver/Vehicle Information Display: Description and Operation
Vehicle Information Center
General Information
The Vehicle Information Center (VIC) is an available option on Grand Cherokee models. The VIC module replaces the standard equipment Graphic
Display Module. The VIC is mounted in the lower center stack area of the instrument panel, above the ash receiver and below the climate controls.
The VIC consists of a multi-colored vacuum fluorescent display (VFD) screen with a vehicle outline. The VIC is able to display four functions in a
choice of five languages. The display functions include:
-
Current time (12 or 24 hour clock), day, and date
-
Monitor specific vehicle operating systems and alert the driver of a malfunction in a monitored system
-
Display service reminders or the distance to the next service interval
-
The current transfer case mode of operation (four-wheel drive models).
The display language choices include:
-
English
-
French
-
German
-
Italian
-
Spanish.
The VIC receives input from hard-wired sensors and over the Chrysler Collision Detection (CCD) data bus network. In response to these inputs, the VIC
offers a combination of graphic and message displays, and provides requests for audible chime alerts to the Body Control Module (BCM) on the CCD
data bus.
For diagnosis of the VIC module or the CCD data bus, refer to the proper Computers and Control Systems/Body Control Module/Testing and Inspection
Procedures. The VIC module cannot be repaired. If damaged or faulty, the entire module must be replaced.
Circuit Operation
CIRCUIT OPERATION
Several fuses supply power to the Vehicle Information Center (VIC). When the ignition switch is in the RUN position it connects circuit A1 from
fuse 8 in the PDC to circuit A22. Circuit A22 feeds circuit F83 through fuse 6 in the junction block. Circuit F83 supplies voltage to the VIC.
Circuit A7 from fuse 15 in the PDC powers circuit F60 through fuse 20 in the junction block. Circuits A7 and F60 are HOT at all times. Circuit
F60 feeds the VIC.
Circuit A6 from fuse 13 in the PDC powers circuit 366 through fuse 17 in the junction block. Circuit 366 connects to the headlamp switch. When
the headlamp switch is in the PARK or LOW position, it connects circuit 366 to circuit L90. Circuit L90 connects to the VIC. Circuit E2 from the
Body Control Module (BCM) powers the illumination lamps in the VIC.
Circuits Z1 and Z2 provide ground for the VIC.
System Operation
SYSTEM OPERATION
Models equipped with an optional Vehicle Information Center (VIC) have a "turn signal on" warning feature. The VIC module monitors the turn
signal circuit from the combination flasher. The VIC module will display the message, Turn Signal On, and send a request to the Body Control
Module (BCM) on the Chrysler Collision Detection (CCD) data bus network for six chime tones, if a turn signal remains activated for more than
approximately one-half mile of driving.
Refer to the proper Computers and Control Systems/Body Control Module/Testing and Inspection Procedures for diagnosis and service of the
BCM or the CCD data bus.
