• Brake indicator: turned on if parking brake is

ON, there is a brake failure due to loss of brake fluid

pressure, or low fluid level.

• Front Fog indicator: when the front fog lamps

are selected ON.

• High Beam indicator: turned on when the high

beam lamps are selected ON.

• Malfunction Indicator (MIL) (ISO Symbol): is

turned on by the Powertrain Control Module (PCM).

If a malfunction has occurred that effects the emis-

sions system. There should be a diagnostic trouble

code set in the memory.

• Seat Belt indicator: turned on when the ignition

is turned ON and drivers seat belt is unbuckled. The

lamp is controlled though the Occupant Restraint

Controller (ORC).

• Trunk Ajar indicator: turned on when the

trunk is not latched. This will only illuminate when

the instrument cluster is awake.

OPERATION - EXPORT

All gauges are the analog type. When the ignition

switch is moved to the OFF position, the cluster

drives each gauge to its lowest position. The individ-

ual gauges in the cluster and gauge pack are not ser-

viceable and require complete replacement of the

cluster or gauge pack as an assembly if one or more

gauges are inoperable.

The gauges are the magnetic air-core type. When

the ignition switch is OFF, the gauge pointers should

rest at or below the lowest graduation. The instru-

ment cluster and gauge pack may be checked quickly

by using the cluster self-diagnostics (Refer to 8 -

ELECTRICAL/INSTRUMENT CLUSTER - STAN-

DARD PROCEDURE - SELF-DIAGNOSTICS). After

bulb check, (with the key in the RUN position and

engine running) all MODULE warning indicators

(Airbag, ABS, MIL, Charging System, etc.) should be

extinguished. If any of these indicators stay ON

(excluding seat belt-if unbuckled), use the DRB IIIt

scan tool to determine module faults. Also refer to

the proper Body Diagnostic Procedures manual for

cluster self-diagnostic results.

NOTE: If any of the gauge pointers are stuck on the

wrong side of the pointer stop, perform the instru-

ment cluster self-diagnostic check (Refer to 8 -

ELECTRICAL/INSTRUMENT CLUSTER - STANDARD

PROCEDURE - SELF-DIAGNOSTICS). This will

“sweep” all the pointers to the correct side of the

pointer stop.

One 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 in self-diagnos-

tic mode (Refer to 8 - ELECTRICAL/INSTRUMENT

CLUSTER - STANDARD PROCEDURE - SELF-DI-

AGNOSTICS). Some of the indicators will come on

briefly for a bulb check when the ignition is turned

from OFF to ON. The LED’s are non serviceable and

if one or more warning indictor LED’s are out, the

entire cluster must be replaced.

The bulbs are serviceable. They are the fog lamp,

high beam, left and right turn signal, engine ISO

symbol, and ABS indicators.

In the event that the instrument cluster looses

communication with all other modules on the Pro-

grammable Communication Interface (PCI) data bus,

the cluster will display “nobuS” in the LCD display.

The LCD display also displays odometer trip or total

mileage.

The message center indicator lamps are an infor-

mation system that provides the following messages.

• Airbag indicator: is turned on by the Occupant

Restraint Controller (ORC) if a malfunction has

occurred that effects the Airbag system. There should

also be a Diagnostic Trouble Code (DTC) set in the

ORC.

• Antilock Brake indicator: turned on when

there is a detected system fault with the antilock

braking system. The Controller Antilock Brakes

(CAB) will store a DTC when this occurs.
