EFS001A8
PRECAUTIONS FOR TROUBLE DIAGNOSIS
lBefore performing the trouble diagnosis, always read theGI-3, "PRECAUTIONS"to confirm the general
precautions.
lAfter replacement of ESP/TCS/ABS control unit, steering angle sensor, steering parts, suspension parts,
or tires, and adjustment of alignment, always adjust the neutral position of steering angle sensor before
driving.
lWhen the ESP/TCS/ABS control unit is replaced, check that the label on the computer unit is identical
color.
lAfter completing the trouble diagnosis, always erase the malfunctioning memory.BRC-77, "Functions of
CONSULT-II"
lWhen inspection of the continuity or voltage between units is performed, check the connector terminals for
disconnection, looseness, bend, or collapse. If any malfunction is detected, repair or replace the applica-
ble part.
lIntermittent problems may be caused by a malfunction on harness, connector, or terminal. Move the har-
nesses, harness connectors, or terminals by hand to make sure that there is no contact malfunction.
lIf a circuit tester is used for the check, be careful not to forcibly extend any connector terminal.
lFor self-diagnosis, active test, and work support of ESP/TCS/ABS control unit with CONSULT-II, stop and
connect CONSULT-II and select²ABS².
lCONSULT-II self-diagnosis results are displayed without regard to occurrence timing. In some case, the
later ones (timing value is small) appear on the next screen.
lWhile the self-diagnosis results of CONSULT-II shows a malfunction, if CONSULT-II active test is per-
formed, an engine system malfunction may be indicated. In this case, start the engine to resume the nor-
mal screen.
lESP/TCS/ABS system electronically controls the brake operation and engine output. The following symp-
toms may be caused by the normal operations.
Symptom Symptom description Result
Motor operation noiseDuring ESP, TCS, or ABS operation, sometimes a faint noise can be
heard. This is a motor operation noise in the ESP/TCS/ABS actuator.
Normal
Just after the engine starts, the motor operating noise may be heard.
This is a normal status of the system operation check.
System operation check
noiseWhen the engine starts, a²click²noise may be heard from the engine
compartment. This is a normal status of the system operation check.Normal
ESP/TCS operation
(SLIP lamp ON)When the vehicle is passing through a road where the surface friction
coefficient varies or the wheel speed changes suddenly by downshifting
or depressing of the accelerator pedal fully, TCS may be activated tem-
porarily.
Normal
Cancel the ESP/TCS
function for the
inspection on a chas-
sis dynamometer. Before the speedometer inspection, turn ESP OFF switch off to cancel
the ESP/TCS function.
When the accelerator pedal is depressed on a chassis dynamometer,
the vehicle speed will not increase. This is not malfunction, because
TCS is activated by the wheel speed difference between front and rear.
The warning lamp may also illuminate to show²sensor system failure²in
this case. This is not malfunction either, because the stationary front
wheels are detected. Restart the engine, and drive the vehicle at 30 km/
h or higher to check that the warning lamp no longer illuminates.
ABS operation (Longer stop-
ping distance)The stopping distance may be longer for the vehicles with ABS when the
vehicle is driver on snowy and rough road. When driving on the road like
that, slow down the speed.Normal
Sluggish feelDepending on road circumstances, the driver may have a sluggish feel.
This is not abnormal, because the optimum traction has the highest pri-
ority (safety first) by TCS operation. Sometimes the driver has a slight
sluggish feel against the substantial accelerator pedal operation.Normal

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 45.
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 46.
Ground is supplied
lthrough body grounds M27 and M70
lto 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
lfrom ECM terminal 32
lto 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
lfrom terminal 36 (Gasoline engine models) or D1 (Diesel engine models) of the ECM
lto 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
lfrom body grounds, B8 and B18
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 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
lfrom combination meter terminal 42 for the speedometer
lto terminal 20 of 4WD/ABS control unit (without ESP) or 4WD control unit (without ESP).
The speedometer converts the voltage into the vehicle speed displayed.
