System Description
UNIFIED CONTROL METER
ISpeedometer, odo/trip meter, tachometer, fuel gauge and water temperature gauge are controlled totally
by control unit built-in combination meter.
I 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.
I Odo/trip meter segment can be checked in diagnosis mode.
I Meter/gauge can be checked in diagnosis mode.
HOW TO CHANGE THE DISPLAY FOR ODO/TRIP METER

POWER SUPPLY AND GROUND CIRCUIT
Power is supplied at all times
Ithrough 10A fuse [No. 16, located in the fuse block (J/B)]
I to combination meter terminal 27.
With the ignition switch in the ON or START position, power is supplied
I through 10A fuse [No. 12, located in the fuse block (J/B)]
I to combination meter terminal 28.
Ground is supplied
I through body grounds F36, F47 (LHD models) or M33, M754 (RHD models)
I to combination meter terminal 29.
WATER TEMPERATURE GAUGE
The water temperature gauge indicates the engine coolant temperature.
Thermal transmitter provides a engine coolant temperature signal to combination meter for water temperature
gauge.
TACHOMETER
The tachometer indicates engine speed in revolution per minutes (rpm). ECM provides an engine speed sig-
nal to combination meter for 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
Ifrom body grounds B10 and B18
I through terminal 3 of the fuel level sensor unit and
I through terminal 2 (TD27Ti engine) or 1 (ZD30DDTi engine) of the fuel level sensor unit
I to combination meter terminal 13 for the fuel gauge.
SPEEDOMETER
The combination meter receives a signal from vehicle speed sensor. The speedometer converts the signal into
the vehicle speed displayed.
