ELECTRONIC VEHICLE INFORMATION CENTER
DESCRIPTION
The Electronic Vehicle Information Center (EVIC) fea-
tures a driver-interactive display (2). The display is
located in the lower part of the tachometer (1) on the
right side of the instrument cluster (3). This system
conveniently allows the driver to select a variety of
useful information by pressing the switches mounted
on the center stack of the instrument panel. The EVIC
displays information related to the following:
•
System Status
•
Vehicle information warning message displays
•
Tire Pressure Monitor System — If Equipped
•
Personal Settings (customer programmable fea-
tures)
•
Compass display
•
Outside temperature display
•
Trip computer functions
The EVIC system is comprised of several different components. Those components are:
•
Instrument Cluster
•
Upper instrument panel switch pod
•
Ambient Temperature Sensor
•
Electronic Overhead Module
•
Controller Area Network (CAN) Data Bus
The EVIC display is part of the Instrument Cluster assembly and is not serviced as a separate component. If the
display is inoperative the complete Instrument Cluster assembly must be replaced, (Refer to 8 - ELECTRICAL/IN-
STRUMENT CLUSTER - REMOVAL). If the EVIC switches in the upper instrument panel switch pod are inoperative
and require replacement, Refer to ELECTRICAL/INSTRUMENT CLUSTER/INSTRUMENT PANEL SWITCH POD -
REMOVAL for the appropriate procedure. If the compass position sensor (Electronic Overhead Module) is inopera-
tive and requires replacement, (Refer to 8 - ELECTRICAL/OVERHEAD CONSOLE/UNIVERSAL TRANSMITTER -
REMOVAL) for the appropriate procedure.
OPERATION
The Electronic Vehicle Information Center (EVIC) uses both non-switched and ignition switched sources of battery
current so that some of its features remain operational at any time, while others may only operate with the ignition
switch in the On position. When the ignition switch is turned to the On position, the EVIC display will return to the
last function being displayed before the ignition was turned to the Off position.
The EVIC system is comprised of several different components that communicate over the Controller Area Network
(CAN) Data Bus. If the system is inoperative a scan tool and the appropriate diagnostic information must be used
to diagnose the system.
