r
(harness side) 16W834
Stopper (upper)
FUEL GAUGE SIMPLE TEST NOEHICE
(1) Disconnect, from below the vehicle, the wiring connector
from the fuel gauge unit.
(2) Ground the connector at the harness through a test light.
(3) Turn the ignition key to the ON position.
(4) Check to be
sure that the test light flashes and the fuel
gauge indicator moves.
(5) If both the test light and gauge operate, the circuit to the
gauge unit is normal and the gauge unit itself is faulty.
If the test light flashes but the gauge does not operate, the
gauge is faulty.
If neither the test light nor the gauge operates, the fuel
gauge circuit is faulty.
FUEL GAUGE UNIT INSPECTION NOEHIIF
To check the fuel gauge unit, first remove it from the fuel tank.
For detailed information concerning installation of the fuel
gauge unit, refer to GROUP 4, FUEL SYSTEM - Fuel Tank.
FUEL GAUGE UNIT FLOAT POSITION CHECK
Check to be sure that the height of the fuel gauge float
(relative to the center part of the fuel gauge unit) is within the
standard value range when the float is at the “F” position
(upper limit) and “E” position (lower limit).
Standard value:
A 29.7-34.7 mm (1.170-I .366 in.)
B 183.8-185.8 mm (7.236-7.315 in.)
FUEL GA&E UNIT RESISTANCE CHECK
Confirm that the resistances when the float of the fuel gauge
unit is at the “F” position (top) and the “E” position (bottom)
are within the standard value ranges.
Standard value:
Float position “F” point 14.9-19.1 IR c
Float position “E” point 113.5-126.5 IR’
WATER TEMPERATURE GAUGE SIMPLE T,5$2
(1) Disconnect the wiring connector from the water tempera-
ture gauge unit inside the engine compartment.
(2) Ground the connector at the harness through a test light.
(3) Turn the ignition key to the ON position.
(4) Check to be sure that the test light flashes and the water
temperature gauge indicator moves. ,

8-132 METERS AND GAUGES - Service Adjustment Procedures
(5) If both the test light and gauge operate, the circuit to the
gauge unit is normal and the gauge unit itself is faulty.
If the test light flashes but the gauge does not operate, the
gauge is faulty.
If 1 neither the test light nor the gauge operates, the water
temperature gauge circuit is faulty.

To check the water temperature gauge unit, first remove it
from the intake manifold.
For detailed information concerning installation of the water
temperature gauge unit, refer to GROUP 11, INTAKE AND
EXHAUST SYSTEM - Intake Manifold.
WATER TEMPERATURE GAUGE UNIT RESISTANCE CHECK
Immerse the gauge unit in hot water at 70°C (158°F) and
measure the resistance value with an ohmmeter.
Standard value: 90.5 - 117.5 LR
OIL PRESSURE GAUGE SIMPLE TEST NOEHIFA
(1) Disconnect the wiring connector from the oil pressure
gauge unit inside the engine compartment.
(2) Ground the connector at the harness through a test light.
(3) Turn the ignition key to the ON position.
(4) Check to be sure that the test light illuminates steadily and
the indicator of the oil pressure gauge moves.
(5) If both the test light and gauge operate, the circuit to the
gauge unit is normal and the gauge unit itself is faulty.
If the test light flashes but the gauge does not operate, the
gauge is faulty.
If neither the test light nor the gauge operates, the oil
pressure gauge circuit is faulty.

LIGHTS
Symbol
Operation
Turn signal indicator
+e3 This indicator flashes, as do the same side of turn-signal light
flashes. If the turn-signal light is burnt out, the blinking of
indicator slows down.
This indicator is common with hazard light.

High beam indicator
- This indicator illuminates when the headlights are on high
= beam.

* Door-ajar warning light
This warning light comes on when the door is either open or
not completely closed.
4 Fasten seat belt indicator
This indicator goes on for four to eight seconds when the
ignition key is in “ON” position, even if the driver has fastened
his seat belt.
BRAKE
Brake warning light
This warning light comes on when the ignition key is in “ON”
position, and goes off after the engine has started. This
warning light comes on when the parking brake is applied
or brake fluid level falls less than the specific level.
III Charging warning light This warning light comes on when the ignition key is in
- + “ON” position, and goes off after the engine has started.
This warning light comes on when the drive belt breaks
or the trouble occurs in the charging system.
Oil pressure warning light This warning light comes on when the ignition key is in “ON”
P position, and goes off after the engine has started. This
warning light comes on when the oil fails or the trouble
occurs in the oil circulating system.
00
Overdrive indicator
This indicator will illuminates when the overdrive control
OFF
switch is switched to the “OFF” position.
68R0133
A/T
A/T oil temperature warning light This A/T oil temperature warning light comes on when
TEMP automatic transmission fluid temperature becomes abnor-
mally high.
68WO68
Free-wheeling hub indicator
YEL This indicator comes on when the automatic free-wheeling
hubs are locked.
68WO80
z4 4WD indicator This indicator will light up when the transfer case shift lever is
shifted to the four wheel driving position (either the “4H” or the
“4L” position) and the ignition key is in the “ON” position.
CHECK
EGR
EGR warning light The EGR warning light will illuminate every 50,000 miles of
driving. When this occurs, bring the vehicle to an authorized
dealter to have the EGR system checked.
) STB Revision

8-142 METERS AND GAUGES - EGR Warning System
EGR WARNING SYSTEM
The EGR warning system consists of a microswitch connected
to the odometer, a reset switch, and a warning light bulb.
This system will cause the EGR warning light to light up every
50,000 miles that the vehicle is driven in order to inform the
driver that it is time to check the EGR system.
The warning light bulb will light up when the ignition switch is
set to “ON” while the engine is not running, thus allowing the
driver to confirm that the bulb is not burned out.
RESET SWITCH
Use the switch on the back of the odometer to reset the EGR
warning system.
NOTE
If the speedometer is to be replaced, set the new odometer to
the same reading as the odometer being, removed.
