Electrical Components Inspection".
OK or NG
OK >> GO TO 6.
NG >> Replace fuel level sensor unit or sub fuel level sensor unit.
6.CHECK INSTALLATION CONDITION
Check fuel level sensor unit installation, and check whether the float arm interferes or binds with any compo-
nents inside the arm.

The Fuel Gauge Pointer Fluctuates·Indicator Wrong Value·or Varies.EKS002ZJ
1.CHECK THE FUEL GAUGE POINTER FOR FLUCTUATION
Does the indication value fluctuate during driving or before/after stop?
Does the indication value vary?
YES >> The pointer fluctuation may be caused by fuel level change in the fuel tank.
NO >> Ask the customer about the situation when the symptom occurs in detail, and Preform the trouble
diagnosis. Continuity should not exist.

System DescriptionEKS0030H
UNIFIED CONTROL METER
lSpeedometer, odo/trip meter, tachometer, fuel gauge and water temperature gauge are controlled totally
by control unit built-in combination meter.
lDigital meter is adopted for odo/trip meter.*
*The record of the odo meter is kept even if the battery cable is disconnected. The record of the trip meter
is erased when the battery cable is disconnected.
lOdo/trip meter segment can be checked in diagnosis mode.
lMeter/gauge can be checked in diagnosis mode.
HOW TO CHANGE THE DISPLAY FOR ODO/TRIP METER
NOTE:
Turn ignition switch to the “ON” position to operate odo/trip meter.
POWER SUPPLY AND GROUND CIRCUIT
Power is supplied at all times
lthrough 10A fuse [No. 28, located in the fuse block (J/B)]
lto combination meter terminal 58.
With the ignition switch in the ON or START position, power is supplied
lthrough 10A fuse [No. 11, located in the fuse block (J/B)]
lto combination meter terminal 59.
Ground is supplied
lthrough body grounds M27 and M70
lto combination meter terminal 60.
WATER TEMPERATURE GAUGE
Gasoline engine models
The water temperature gauge indicates the engine coolant temperature. The reading on the gauge is received
engine coolant temperature signal from ECM. ECM is detected by water temperature sensor.
The water temperature gauge is received by a signal
lfrom ECM terminal 32
lto combination meter terminal 66.
The needle on the gauge moves from “C” to “H”

Diesel engine models
The water temperature gauge indicates the engine coolant temperature. The reading on the gauge is based
on the resistance of the thermal transmitter.
As the temperature of the coolant increases, the resistance of the thermal transmitter decreases. A variable
ground is supplied to terminal 66 of the combination meter for the water temperature gauge. The needle on
the gauge moves from “C” to “H”.
TACHOMETER
The tachometer indicates engine speed in revolutions per minute (rpm).
The tachometer is regulated by a signal
lfrom terminal 36 (Gasoline engine models) or D1 (Diesel engine models) of the ECM
lto combination meter terminal 41 for the tachometer.
FUEL GAUGE
The fuel gauge indicates the approximate fuel level in the fuel tank.
The fuel gauge is regulated by a variable ground signal supplied
lfrom body grounds , B107 and B119
lthrough terminal 1 and 3 of the Sub fuel level sensor unit and
lthrough terminal 4 and 1 of the fuel level sensor unit
lto combination meter terminal 40 for the fuel gauge.
SPEEDOMETER
The combination meter provides a voltage signal to the vehicle speed signal from 4WD/ABS control unit (with-
out ESP) or 4WD control unit (with ESP).
The voltage is supplied
lfrom combination meter terminal 42 for the speedometer
lto terminal 20 of 4WD/ABS control unit (without ESP) or 4WD control unit (with ESP).
The speedometer converts the voltage into the vehicle speed displayed.
