GENERAL – How to Use Troubleshooting/Inspection Service Points00-8
WHEN USING THE WARNING LAMP
1. Use the special tool to earth No.1 terminal (diagnosis
control terminal) of the diagnosis connector.
2. To check ABS system, remove the valve relay.
NOTE
That is because the valve relay is off and the warning
lamp remains illuminated if there is a fault in the ABS
system.
3. Turn on the ignition switch.
4. Read out a diagnosis code by observing how the warning
lamp flashes.

WHEN USING THE VOLTMETER
Use the special tool to connect the diagnosis output terminals
and the earth terminal of the diagnosis connector to a voltmeter
and take a reading of the diagnosis codes from the movement
of the needle.

METHOD OF ERASING DIAGNOSIS CODES
WHEN USING THE MUT-II
Connect the MUT-II to the diagnosis connector and erase the diagnosis code.
Caution
Turn off the ignition switch before connecting or disconnecting the MUT-II.
WHEN NOT USING THE MUT-II
(1) Turn the ignition switch to OFF.
(2) After disconnecting the battery cable from the battery (–) terminal for 10 seconds or more, reconnect
the cable.
(3) After the engine has warmed up, run it at idle for about 15 minutes.
INPUT SIGNAL INSPECTION POINTS WITH ETACS-ECU>
WHEN USING THE MUT-II
1. Connect the MUT-II to the diagnosis connector.
Caution
The MUT-II should be connected or disconnected after
turning the ignition switch to the OFF position.
2. If buzzer of the MUT-II sounds once when the each switch
is operated (ON/OFF), the ETACS-ECU input signal for
that switch circuit system is normal.
WHEN USING VOLTMETER
1. Use the special tool to connect a voltmeter between
the earth terminal (No. 4 or 5) and the ETACS terminal
(No. 9) of the diagnosis connector.
2. If the voltmeter indicator deflects once when the each
switch is operated (ON/OFF), the ETACS-ECU input signal
for that switch circuit system is normal.

CONNECTOR MEASUREMENT SERVICE POINTS
Turn the ignition switch to OFF when connecting disconnecting
the connectors, and turn the ignition switch to ON when
measuring if there are no instructions to be contrary.
IF INSPECTING WITH THE CONNECTOR CONNECTED
(WITH CIRCUIT IN A CONDITION OF CONTINUITY)
Waterproof Connectors
Be sure to use the special tool (harness connector). Never
insert a test bar from the harness side, because to do so
will reduce the waterproof performance and result in corrosion.
Ordinary (non-waterproof) Connectors
Check by inserting the test bar from the harness side. Note
that if the connector (control unit, etc.) is too small to permit
insertion of the test bar, it should not be forced; use a special
tool (the extra-thin probe in the harness set for checking
for this purpose.
IF INSPECTING WITH THE CONNECTOR DISCONNECTED

Use the special tool (inspection harness for connector pin
contact pressure in the harness set for inspection).
The inspection harness for connector pin contact pressure
should be used. the test bar should never be forcibly inserted,
as it may cause a defective contact.

Touch the pin directly with the test bar.
Caution
At this time, be careful not to short the connector pins
with the test bars. To do so may damage the circuits
inside the ECU.

GENERAL – Precautions Before Service00-16
SERVICING THE ELECTRICAL SYSTEM
Before replacing a component related to the electrical system
and before undertaking any repair procedures involving the
electrical system, be sure to first disconnect the negative
(–) cable from the battery in order to avoid damage caused
by short-circuiting.
Caution
Before connecting or disconnecting the negative (–) cable,
be sure to turn off the ignition switch and the lighting
switch.
(If this is not done, there is the possibility of
semiconductor parts being damaged.)
APPLICATION OF ANTI-CORROSION AGENTS
AND UNDERCOATS
If oil or grease gets onto the oxygen sensor, it will cause
a drop in the performance of the sensor.
Cover the oxygen sensor with a protective cover when applying
anti-corrosion agents and undercoats.
PRE-INSPECTION CONDITION
“Pre-inspection condition” refers to the condition that the
vehicle must be in before proper engine inspection can be
carried out. If you see the words “Set the vehicle to the
pre-inspection condition.” in this manual, it means to set the
vehicle to the following condition.
Engine coolant temperature: 80–90C
Lamps, electric cooling fan and all accessories: OFF
M/T: Neutral
VEHICLE WASHING
If high-pressure car-washing equipment or steam car-washing
equipment is used to wash the vehicle, be sure to note the
following information in order to avoid damage to plastic
components, etc.
Spray nozzle distance: Approx. 40 cm or more
Spray pressure: 3,900 kPa or less
Spray temperature: 82C or less
Time of concentrated spray to one point: within 30 sec.
Approx.
40 cm

GENERAL – Precautions Before Service00-17
MUT-II
Refer to the MUT-II INSTRUCTION MANUAL for instructions
on handling the MUT-II.
Connect the MUT-II to the diagnosis connector as shown
in the illustration.
Caution
Connection and disconnection of the MUT-II should
always be made with the ignition switch in the OFF
position.

GENERAL – Special Handling Instruments for Towing00-20
SPECIAL HANDLING INSTRUMENTS FOR TOWING
Towing methodsRemarks
If a tow truck is used
Lifting method for 4 wheels – GoodFor 4WD models, the basic principle is that all
four wheels are to be raised before towing.
The shift lever should be set to 1st gear and
the parking brake should be applied.
Front wheels lifted – No goodThe vehicle must not be towed by placing only
its front wheels or only the rear wheels on a
rolling dolly, because to do so will result in
deterioration of the viscous coupling and result
in the viscous coupling causing the vehicle to
jump forward suddenly.
Front wheels lifted – No goodIf only the front wheels or only the rear wheels
are lifted for towing, the bumper will be damaged.
In addition, lifting of the rear wheels causes
the oil to flow forward, and may result in heat
damage to the rear bushing of the transfer, and
so should never be done.
Rear wheels lifted – No good
Towing by rope or cable – GoodThe front and rear wheels must rotate normally.
Both running and driving systems must function
normally.
The shift lever must be set to the neutral position
and the ignition key must be set to “ACC”.
