• EVIC Display (Left VF Display)
The cluster Thin Filmed Transistor (TFT) screen (if

so equipped) shall have the capability to display vehi-
cle navigation information (such as maps and turn-
by-turn direction) as input by the navigation module.

ELECTRONIC VEHICLE INFORMATION CENTER

The Electronic Vehicle Information Center (EVIC)

is part of the instrument cluster. The EVIC display
screen is located in the left lower corner of the clus-
ter.

The EVIC portion of the instrument cluster con-

tains a central processing unit that interfaces with
other electronic modules in the vehicle over the Pro-
grammable Communications Interface (PCI) data bus
circuit. The PCI data bus circuit allows the sharing
of sensor information.

The EVIC “Menu” push button provides the vehicle

operator with a user interface, which allows the
selection of several optional customer programmable
electronic features to suit individual preferences.
Refer to the owners manual for more information on
the customer programmable feature options. Data
input for all EVIC functions is received through the
PCI data bus circuit. The EVIC uses its internal pro-
gramming and all of its data inputs to calculate and
display the requested data.

The EVIC cannot be repaired. If found defective,

the entire cluster must be replaced.

INSTRUMENT CLUSTER

OPERATION

The Instrument Cluster (IC) receives and sends

messages via the Programmable Communication
Interface (PCI) data bus. The indicator lamps will
illuminate briefly for a bulb check when the ignition
is turned from off to run. All of the gauges receive
their information via the PCI Bus from the Next
Generation Controller (NGC) and the Body Control
Module (BCM).

The Customer Information System (CIS) main con-

trol module is the cluster. The cluster uses a micro-
processor to process information to/from the PCI data
bus and direct hard wired inputs from the Park
Brake Switch, EVIC, Turn Signals, and optional NAV
buttons. The Pulse Width Modulated (PWM) Dim-
ming hard wired signal is provided by the cluster, to
modules and lamps that require PWM Dimming. The
PWM Dimming hard wired Signal is created from the
Dimming PCI bus message sent by the BCM. The
cluster will receive a

9Wake-up9 signal from the BCM

and a

9battery9 feed from the Integrated Power Mod-

ule (IPM) for power control/supply. cluster PCI data
bus communicate with the Controller Anti-Lock
Brake (CAB), Body Control Module (BCM), Electronic
Vehicle Information Center (EVIC), Driver Door Mod-
ule (DDM), Intelligent Power Module (IPM), Naviga-
tion Module (NAV), Next Generation Controller (NGC
combines former Powertrain Control Module and
Transmission Control Module functions), Occupant
Restraint Controller (ORC), Passenger Door Module
(PDM),

Sentry

Key

Remote

Entry

Module

(SKREEM), and the DRBIII

t scan tool (via the data

link connector).

Red-Green-Blue (RGB) Video data will be received

from the Navigation module, for display on the Thin
Filmed Transistor (TFT) screen (if equipped).

The Instrument Panel Switch Pod is the secondary

part of the CIS. The switch pod will contain an Ana-
log Clock (w/time adjust button), Hazard Switch,
EVIC and NAV (optional) controls, and Vehicle Theft
Security System (VTSS) LED.

INSTRUMENT CLUSTER

INSTRUMENT CLUSTER (Continued)

The Instrument Cluster has four gauges: Speedom-

eter, tachometer, fuel, and temperature. The gauges
and the LED’s are not individually replaceable
thereby

requiring

complete

replacement

the

Instrument Cluster if a repair is necessary. In the
event that the Instrument Cluster loses communica-
tion with other modules on the PCI Bus, the cluster
will display

9no bus9 in the VF display.

The Trip/Reset button is used to switch the display

from trip to total mileage. Holding the button when
the display is in the trip mode will reset the trip
mileage. This button is also used to put the cluster
into self-diagnostic mode. The odometer display uses
blue-green vacuum fluorescent digital characters.
The Instrument Cluster uses a vacuum-fluorescent
shift indicator (PRND8) with auto stick.

CHARGING SYSTEM INDICATOR (Fig. 2) -

This Light Emitting Diode (LED) indicator monitors
the electrical system voltage. The LED should turn
on momentarily as the engine is started. If the LED
stays on or turns on while driving, it indicates a
problem with the charging system. Immediate service
should be obtained.

AIRBAG INDICATOR (Fig. 3) - This Light Emit-

ting Diode (LED) turns on and remains on for 6 to 8
seconds as a bulb check when the ignition switch is
first turned ON. If the light is not on during starting,
stays on, or turns on while driving, refer to the
appropriate Body Diagnostic Procedures manual.

LOW FUEL INDICATOR (Fig. 4) - This Light

Emitting Diode (LED) indicator will illuminate when
the fuel level reaches a predetermined low level of
fuel and a chime will sound. It will stay lit until the
fuel level is raised.

BRAKE WARNING INDICATOR (Fig. 5) - This

Light Emitting Diode (LED) indicator monitors vari-
ous brake functions, including brake fluid level and
parking brake application. If the LED turns on, it
may indicate that the parking brake is applied or
there is a low brake fluid level. The dual brake sys-
tem provides a reserve braking capacity in the event
of a failure to a portion of the hydraulic system. Fail-
ure of either half of the dual brake system is indi-
cated by the Brake Warning Indicator which will
turn on when the brake fluid level in the master cyl-
inder has dropped below a specified level. The LED
will remain on until the cause is corrected. The LED
may

flash

momentarily

during

sharp

cornering

maneuvers which change fluid level conditions. The
vehicle should have service performed. If brake fail-
ure is indicated, immediate repair is necessary. Vehi-
cles equipped with Anti-Lock brakes (ABS), are also
equipped with Electronic Brake Force Distribution
(EBD). In the event of an EBD failure, the Brake
Warning Indicator will turn on along with the ABS
Indicator. Immediate repair to the ABS system is
required. The operation of the Brake Warning Indica-
tor can be checked by turning the ignition switch
from the OFF position to the ON position. The LED
should illuminate for approximately two seconds. The
LED should then turn off unless the parking brake is
applied or a brake fault is detected. If the LED does
not illuminate, refer to the appropriate Body Diag-
nostic Procedures manual. The LED also will turn on
when the parking brake is applied with the ignition
switch in the ON position. This LED shows only that
the parking brake is applied. It does not show the
degree of brake application.

FRONT FOG LAMP INDICATOR (Fig. 6) - This

Light Emitting Diode (LED) indicator shows the
front fog lights are ON.

HIGH BEAM INDICATOR (Fig. 7) - This Light

Emitting Diode (LED) shows that the headlights are
on high beam. Pull the Multi-Function lever towards
the steering wheel to switch the headlights from high
or low beam.

HIGH ENGINE TEMPERATURE INDICATOR

(Fig. 8) - This Light Emitting Diode (LED) warns of
an overheated engine condition. If this LED is accom-
panied by a continuous chime, the engine tempera-
ture is critically hot, and the vehicle should be
turned off immediately. The vehicle should be ser-
viced as soon as possible.

ABS INDICATOR (Fig. 9) - This Light Emitting

Diode (LED) monitors the Anti-Lock Brake System.
The LED will turn on when the ignition switch is
turned to the ON position and may stay on for as
long as four seconds. If the ABS indicator remains on
or turns on while driving, it indicates that the Anti-
Lock portion of the brake system is not functioning
and that service is required. However, the conven-
tional brake system will continue to operate normally
if the BRAKE warning indicator is not on. If the ABS
indicator is on, the brake system should be serviced
as soon as possible to restore the benefits of Anti-
Lock brakes. If the ABS indicator does not turn on
when the Ignition switch is turned to the ON posi-
tion, refer to the appropriate Body Diagnostic Proce-
dures manual.

MALFUNCTION INDICATOR (Fig. 10) - This

Light Emitting Diode (LED) indicator is part of an
onboard diagnostic system called OBD that monitors
engine and automatic transmission control systems.
The indicator will illuminate when the key is in the
ON position before engine start. If the LED does not
come on when turning the key from OFF to ON, have
the condition checked promptly. Certain conditions
such as a loose or missing gas cap, poor fuel quality,
etc. may illuminate the indicator after engine start.
The vehicle should be serviced if the indicator stays
on through several of your typical driving cycles. In
most situations the vehicle will drive normally and
will not require towing. The Malfunction Indicator
flashes to alert you to serious conditions that could
lead to immediate loss of power or severe catalytic
converter damage. The vehicle should be serviced as
soon as possible if this occurs.

LOW OIL PRESSURE INDICATOR (Fig. 11) -

This Light Emitting Diode (LED) shows low engine

oil pressure. The LED should turn on momentarily
when the engine is started. If the LED turns on
while driving, stop the vehicle and shut off the
engine as soon as possible. A continuous chime will
sound when this LED turns on. Do not operate the
vehicle until the cause is corrected. This LED does
not show how much oil is in the engine. The engine
oil level must be checked under the hood.

SEAT BELT INDICATOR (Fig. 12) - The Light

Emitting Diode (LED will turn on when the ignition
switch is turned to the ON position as a reminder to
“buckle up”. The LED will remain on until the driv-
er’s seat belt is buckled. The chime will sound for 6
seconds, or until the seat belt is buckled.

TIRE PRESSURE MONITOR SYSTEM INDI-

CATOR (Fig. 13) - This Light Emitting Diode (LED)
will turn on when there is a low tire pressure condi-
tion. The LED will also turn on if a problem exist
with any tire sensor. The LED will remain on until
the tire pressure is properly set or the problem with
the sensor is corrected. This LED will turn on mon-
etarily as a bulb check when the engine is started.

TRACTION CONTROL OR ACCELERATION

SKID CONTROL (ASR) INDICATOR (Fig. 14) -
This Light Emitting Diode (LED) indicator illumi-
nates momentarily as a bulb check when the ignition
switch is first turned ON. Extended heavy use of
Traction Control/ASR may cause the system to deac-
tivate and turn on the Traction Control/ASR Indica-
tor. This is to prevent overheating of the brake
system and is a normal condition. The system will
remain disabled for about 4 minutes until the brakes
have cooled. The system will automatically reactivate
and turn off the Traction Control/ASR Indicator. The
traction control/ASR indicator will turn on if:

• The traction control/ASR system is in use.

• The Traction Control/ASR switch has been used

to turn the system OFF.

• There is a Traction Control/ASR System mal-

function.
