wheel drive lock indicator lamp should light. If OK,
replace the faulty transfer case switch. If not OK, go
to Step 5.

(5) Turn the ignition switch to the Off position.

Disconnect and isolate the battery negative cable.
Disconnect the wire harness connector at the Con-
troller Anti-Lock Brake (CAB). Remove the instru-
ment cluster. With the transfer case switch wire
harness connector still disconnected, check for conti-
nuity between the four wheel drive lock indicator
lamp driver circuit cavity of the instrument cluster
wire harness connector B and a good ground. There
should be no continuity. If OK, go to Step 6. If not
OK, repair the shorted four wheel drive lock indica-
tor lamp driver circuit as required.

(6) Check for continuity between the four wheel

drive lock indicator lamp driver circuit cavities of the
instrument cluster wire harness connector B and the
transfer case switch wire harness connector. There
should be continuity. If OK, replace the faulty bulb.
If not OK, repair the open four wheel drive lock indi-
cator lamp driver circuit as required.

HEADLAMP HIGH BEAM INDICATOR LAMP

The diagnosis found here addresses an inoperative

headlamp high beam indicator lamp condition. If the
problem being diagnosed is related to inoperative
headlamp high beams, refer to Headlamp Diagno-
sis in the Diagnosis and Testing section of Group 8L
- Lamps for diagnosis of the headlamp system. If no
headlamp system problems are found, the following
procedure will help locate an open in the high beam
indicator lamp circuit. For complete circuit diagrams,
refer to Instrument Cluster in the Contents of
Group 8W - Wiring Diagrams.

(1) Disconnect and isolate the battery negative

cable. Remove the instrument cluster.

(2) Connect the battery negative cable. Turn the

headlamps on and select the high beams with the
multi-function switch stalk. Check for battery voltage
at the high beam indicator driver circuit cavity of the
instrument cluster wire harness connector B. If OK,
replace the faulty bulb. If not OK, repair the open
high beam indicator driver circuit to the headlamp
dimmer (multi-function) switch as required.

LOW WASHER FLUID WARNING LAMP

The diagnosis found here addresses an inoperative

low washer fluid warning lamp condition. If the prob-
lem being diagnosed is related to lamp accuracy, be
certain to confirm that the problem is with the lamp
or washer fluid level sensor and not with a damaged
or empty washer fluid reservoir. Inspect the reservoir
for proper fluid level and signs of damage or distor-
tion that could affect sensor performance before you
proceed with lamp diagnosis. Refer to Washer Sys-

tem in the Diagnosis and Testing section of Group
8K - Wiper and Washer Systems for more informa-
tion. For complete circuit diagrams, refer to Instru-
ment Cluster in the Contents of Group 8W - Wiring
Diagrams.

(1) Check the fused ignition switch output (run/

start) fuse in the junction block. If OK, go to Step 2.
If not OK, repair the shorted circuit or component as
required and replace the faulty fuse.

(2) Turn the ignition switch to the On position.

Check for battery voltage at the fused ignition switch
output (run/start) fuse in the junction block. If OK,
go to Step 3. If not OK, repair the open fused ignition
switch output (run/start) circuit to the ignition switch
as required.

(3) Turn the ignition switch to the Off position.

Disconnect the wire harness connector from the
washer fluid level sensor. Install a jumper wire
between the two cavities of the washer fluid level
sensor wire harness connector. Turn the ignition
switch to the On position. About thirty seconds after
the ignition switch is turned to the On position, the
low washer fluid warning lamp should light. Turn
the ignition switch to the Off position. Remove the
jumper wire from the washer fluid level sensor con-
nector. Turn the ignition switch to the On position
and, following the cluster bulb check sequence, the
lamp should go off. If OK, replace the faulty washer
fluid level sensor. If not OK, go to Step 4.

NOTE: If the ignition switch is in the On position
when the washer fluid level sensor circuit is
grounded, the instrument cluster programming will
double the low washer fluid warning lamp illumina-
tion delay time from thirty seconds to about sixty
seconds. This feature is intended to compensate for
the effects of washer fluid sloshing within the
washer fluid reservoir while the vehicle is being
driven.

(4) Turn the ignition switch to the Off position.

Check for continuity between the ground circuit cav-
ity of the washer fluid level sensor wire harness con-
nector

and

a

good

ground.

There

should

be

continuity. If OK, go to Step 5. If not OK, repair the
open ground circuit to ground as required.

(5) Disconnect and isolate the battery negative

cable. Remove the instrument cluster. With the
washer fluid level sensor wire harness connector still
disconnected, check for continuity between the low
washer fluid level sense circuit cavity of the instru-
ment cluster wire harness connector B and a good
ground. There should be no continuity. If OK, go to
Step 6. If not OK, repair the shorted low washer
fluid level sense circuit as required.

(6) Check for continuity between the low washer

fluid level sense circuit cavities of the instrument

cluster wire harness connector B and the washer
fluid level sensor wire harness connector. There
should be continuity. If OK, replace the faulty bulb.
If not OK, repair the open low washer fluid level
sense circuit as required.

SECURITY LAMP

The diagnosis found here addresses an inoperative

security lamp condition. If the problem being diag-
nosed is an inaccurate security lamp, refer to Vehi-
cle Theft Security System in the Diagnosis and
Testing section of Group 8Q - Vehicle Theft/Security
Systems for diagnosis. For complete circuit diagrams,
refer to Instrument Cluster in the Contents of
Group 8W - Wiring Diagrams.

(1) Check the fused B(+) fuse in the junction block.

If OK, go to Step 2. If not OK, repair the shorted cir-
cuit or component as required and replace the faulty
fuse.

(2) Check for battery voltage at the fused B(+) fuse

in the junction block. If OK, go to Step 3. If not OK,
repair the open fused B(+) circuit to the battery as
required.

(3) Disconnect and isolate the battery negative

cable. Remove the Central Timer Module (CTM). Dis-
connect the CTM wire harness connectors. Connect
the battery negative cable. Install a jumper wire
between the VTSS indicator driver circuit cavity of
the 18-way CTM wire harness connector and a good
ground. The security lamp should light. If OK, use a
DRB scan tool and the proper Diagnostic Procedures
manual to diagnose the Vehicle Theft Security Sys-
tem (VTSS) and the CTM. If not OK, go to Step 4.

(4) Disconnect and isolate the battery negative

cable. Remove the instrument cluster. Check for con-
tinuity between the fused B(+) circuit cavity of the
instrument cluster wire harness connector A and the
fused B(+) fuse in the junction block. There should be
continuity. If OK, go to Step 5. If not OK, repair the
open fused B(+) circuit to the fuse in the junction
block as required.

(5) Check for continuity between the VTSS indica-

tor driver circuit cavities of the instrument cluster
wire harness connector A and the 18-way CTM wire
harness connector. There should be continuity. If OK,
refer to Instrument Cluster - Self-Diagnostic Test
in the Diagnosis and Testing section of this group for
further diagnosis of the security lamp and the instru-
ment cluster circuitry. If not OK, repair the open
VTSS indicator driver circuit as required.

TURN SIGNAL INDICATOR LAMP

The diagnosis found here addresses an inoperative

turn signal indicator lamp condition. For any other
turn signal problem, refer to Turn Signal and Haz-
ard Warning Systems in the Diagnosis and Testing
section of Group 8J - Turn Signal and Hazard Warn-
ing Systems for further diagnosis. If no turn signal or
hazard warning system problem is found, the follow-
ing procedure will help locate a short or open in the
indicator lamp circuit. For complete circuit descrip-
tions, refer to Instrument Cluster in the Contents
of Group 8W - Wiring Diagrams.

(1) Disconnect and isolate the battery negative

cable. Remove the instrument cluster.

(2) Connect the battery negative cable. Activate

the hazard warning system by moving the hazard
warning switch button to the On position. Check for
battery voltage at the inoperative (right or left) turn
signal circuit cavity of the instrument cluster wire
harness connector B. There should be a switching (on
and off) battery voltage signal. If OK, replace the
faulty (right or left) turn signal indicator lamp bulb.
If not OK, repair the open (right or left) turn signal
circuit to the turn signal/hazard warning (multi-func-
tion) switch as required.
