DISASSEMBLY
1. Check end play of front drive sprocket.Standard:0 - 0.15 mm (0 - 0.0059 in)
If end play is beyond the maximum value, check front drive
sprocket and clutch gear for wear.
2. Remove retaining ring, speedometer drive gear and steel ball.
Be careful not to lose the steel ball.
3. Remove snap ring and spacer.
4. Press out front drive sprocket with mainshaft rear bearing and clutch gear together.
5. Remove needle bearing.
6. Remove bearing retainer and then remove snap ring and spacer.

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
NOTE:
Turn ignition switch to the ªONº position to operate 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.
AMBIENT TEMPERATURE GAUGE
Ambient temperature sensor provides the signal for ambient temperature to combination meter.

Combination Meter Self-Diagnosis
PERFORMING SELF-DIAGNOSIS MODE
1. Turn the ignition switch to the ªLOCKº position.
2. Press both reset buttons on the combination meter and keep them depressed.
3. Turn the ignition switch to the ªONº position, while keeping the reset buttons pressed.
4. Release both reset buttons within 5 seconds after ignition switch is ªONº, then self-diagnosis will start. Thesequence (A to I) is activated by press the either reset buttons.
NOTE:
If either reset button is not pressed for 20 seconds at each step or if the ignition switch is turned OFF, the
self-diagnosis mode is exited.

2 times)
The odo trip meter segment flashes during the sweep move-
ment.
G) Error 1
(Bit 0 - Bit 3)
SEL441X
The segment of each bit displays ª0º, meaning no failure. If
the bit(s) displays figures other than ª0º, the item of the bit
has failed.
