time four-wheel drive 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.
Remove the instrument cluster. With the transfer
case switch wire harness connector still disconnected,
check for continuity between the full time four wheel
drive 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 full time four
wheel drive indicator lamp driver circuit as required.
(6) Check for continuity between the full time four
wheel drive 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 full time four wheel
drive indicator lamp driver circuit as required.
FOUR-WHEEL DRIVE INDICATOR LAMP - PART TIME
The diagnosis found here addresses an inoperative
four-wheel drive indicator lamp condition. If the
problem being diagnosed is related to lamp accuracy,
be certain to confirm that the problem is with the
lamp or switch and not with a damaged or inopera-
tive transfer case or transfer case linkage. Refer to
NV231 Diagnosis or NV242 Diagnosis in the Diag-
nosis and Testing section of Group 21 - Transmission
for more information. If no transfer case problem is
found, the following procedure will help locate a
short or open in the indicator lamp circuit. For com-
plete circuit diagrams, refer to Instrument 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 and isolate the battery negative cable.
Disconnect the transfer case switch wire harness con-
nector. Check for continuity between the ground cir-
cuit cavity of the transfer case switch wire harness
connector and a good ground. There should be conti-
nuity. If OK, go to Step 4. If not OK, repair the open
ground circuit to ground as required.
(4) Connect the battery negative cable. Turn the
ignition switch to the On position. Install a jumper
wire between the part time four wheel drive indicator
lamp driver circuit cavity of the transfer case switch
wire harness connector and a good ground. The part
time four-wheel drive 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.
Remove the instrument cluster. With the transfer
case switch wire harness connector still disconnected,
check for continuity between the part time four
wheel drive 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 part time
four wheel drive indicator lamp driver circuit as
required.
(6) Check for continuity between the part time
four wheel drive 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 part time four wheel
drive indicator 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 A. 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
