System DescriptionEKS002Z7
UNIFIED CONTROL METER
●Speedometer, odo/trip meter, tachometer, fuel gauge and water temperature gauge are controlled totally
by control unit built-in combination meter.
●Digital 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.
●Odo/trip meter segment can be checked in diagnosis mode.
●Meter/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
●through 10A fuse [No. 28, located in the fuse block (J/B)]
●to combination meter terminal 45.
With the ignition switch in the ON or START position, power is supplied
●through 10A fuse [No. 11, located in the fuse block (J/B)]
●to combination meter terminal 46.
Ground is supplied
●through body grounds M27 and M70
●to combination meter terminal 47.
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
●from ECM terminal 32
●to combination meter terminal 55.
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 55 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
●from terminal 36 (Gasoline engine models) or D1 (Diesel engine models) of the ECM
●to combination meter terminal 54 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
●from body grounds, B8 and B18
●through terminals 4 and 1 of the fuel level sensor unit and
●through terminals 1 and 3 of the Sub fuel level sensor unit
●to combination meter terminal 51 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
●from combination meter terminal 52 for the speedometer
●to terminal 20 of 4WD control unit (with ESP) or 4WD/ABS control unit (without ESP).
The speedometer converts the voltage into the vehicle speed displayed.
