(Refer to 5 - BRAKES - DIAGNOSIS AND TEST-
ING). If no brake system problem is found, the fol-
lowing procedures will help to locate a shorted or
open circuit, or a faulty switch input. Refer to the
appropriate wiring information. The wiring informa-
tion includes wiring diagrams, proper wire and con-
nector repair procedures, details of wire harness
routing and retention, connector pin-out information
and location views for the various wire harness con-
nectors, splices and grounds.
WARNING: ON VEHICLES EQUIPPED WITH AIR-
BAGS, DISABLE THE SUPPLEMENTAL RESTRAINT
SYSTEM BEFORE ATTEMPTING ANY STEERING
WHEEL, STEERING COLUMN, DRIVER AIRBAG,
PASSENGER AIRBAG, OR INSTRUMENT PANEL
COMPONENT DIAGNOSIS OR SERVICE. DISCON-
NECT AND ISOLATE THE BATTERY NEGATIVE
(GROUND) CABLE, THEN WAIT TWO MINUTES FOR
THE SYSTEM CAPACITOR TO DISCHARGE BEFORE
PERFORMING FURTHER DIAGNOSIS OR SERVICE.
THIS IS THE ONLY SURE WAY TO DISABLE THE
SUPPLEMENTAL RESTRAINT SYSTEM. FAILURE TO
TAKE THE PROPER
RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT
AND POSSIBLE PERSONAL INJURY.
INDICATOR ILLUMINATES DURING BULB TEST, BUT DOES
NOT WHEN PARK BRAKE APPLIED
(1) Disconnect and isolate the battery negative
cable. Disconnect the floor wire harness connector for
the park brake switch from the switch terminal.
Apply the parking brake. Check for continuity
between the park brake switch terminal and a good
ground. There should be continuity. If OK, go to Step
2. If not OK, replace the faulty park brake switch.
(2) Disconnect the headlamp and dash wire har-
ness connector for the brake warning indicator
switch from the switch terminals. Check for continu-
ity between the red brake warning indicator driver
(G9) circuit cavities of the floor wire harness connec-
tor for the park brake switch and the headlamp and
dash wire harness connector for the brake warning
indicator switch. There should be continuity. If not
OK, repair the open red brake warning indicator
driver (G9) circuit between the park brake switch
and the brake warning indicator switch as required.
INDICATOR REMAINS ILLUMINATED - BRAKE SYSTEM
CHECKS OK
(1) Disconnect and isolate the battery negative
cable. Remove the instrument cluster from the
instrument panel. Disconnect the instrument panel
wire harness connector (Connector C2) for the instru-
ment cluster from the connector receptacle on the
back of the cluster housing. Disconnect the headlamp

and dash wire harness connector for the brake warn-
ing indicator switch from the switch terminals.
Check for continuity between the red brake warning
indicator driver circuit (G99) cavity of the headlamp
and dash wire harness connector for the brake warn-
ing indicator switch and a good ground. There should
be no continuity. If OK, go to Step 2. If not OK,
repair the shorted red brake warning indicator driver
circuit (G99) between the brake warning indicator
switch and the instrument cluster as required.
(2) Disconnect the floor wire harness connector for
the park brake switch from the switch terminal.
Check for continuity between the red brake warning
indicator driver circuit (G9) cavity of the headlamp
and dash wire harness connector for the brake warn-
ing indicator switch and a good ground. There should
be no continuity. If OK, go to Step 3. If not OK,
repair the shorted red brake warning indicator driver
circuit (G9) between the brake warning indicator
switch and the park brake switch as required.
(3) Check for continuity between each of the two
terminals of the brake warning indicator switch and
a good ground. In each case, there should be no con-
tinuity. If OK, go to Step 4. If not OK, replace the
faulty brake warning indicator switch.
(4) Check for continuity between the terminal of
the park brake switch and a good ground. There
should be no continuity with the park brake released,
and continuity with the park brake applied. If not
OK, replace the faulty park brake switch.
CHECK GAUGES INDICATOR
DESCRIPTION
A check gauges indicator is standard equipment on
all instrument clusters. The check gauges indicator is
located on the lower edge of the instrument cluster,
to the right of center. The check gauges indicator
consists of a stencil-like cutout of the words "CHECK
GAUGES" in the opaque layer of the instrument
cluster overlay. The dark outer layer of the overlay
prevents the indicator from being clearly visible
when it is not illuminated. A red Light Emitting
Diode (LED) behind the cutout in the opaque layer of
the overlay causes the "CHECK GAUGES" text to
appear in red through the translucent outer layer of
the overlay when the indicator is illuminated from
behind by the LED, which is soldered onto the
instrument cluster electronic circuit board. The check
gauges indicator is serviced as a unit with the instru-
ment cluster.

OPERATION

The check gauges indicator gives an indication to
the vehicle operator when certain instrument cluster
