OPERATION

DWhen the ignition switch is turned “ON”, the
blower relay is energized. If the blower switch
is turned “ON” (LO, ML, MH, or HI position)
in this condition, the blower is activated through
the circuit via resistor at a speed corresponding
to the blower switch position.TROUBLESHOOTING HINTS

1. Blower motor is energized at one switch position
and not energized at another.
DCheck resistor.
DCheck blower switch.
2. Blower motor is energized only when switch
is positioned in HI.
DCheck resistor.

DIAGNOSIS FUNCTION
METHOD OF READING DIAGNOSIS CODES
WHEN USING THE MUT-II
Connect the MUT-IIto the diagnosis connector and take a
reading of the diagnosis codes.
Caution
Turn the ignition switch to “LOCK”(OFF) position before
connecting or disconnecting the MUT-II.

WHEN USING THE WARNING LAMP
1. Use the special tool to earth No.1 terminal (diagnosis
control terminal) of the diagnosis connector.
2. Turn the ignition switch to “ON” position.
3. Read out a diagnosis code by observing how the warning
lamp flashes.

WHEN NOT USING THE MUT-II
1. Turn the ignition switch to “LOCK”(OFF) position.
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 CHECK
WHEN USING THE MUT-II
1. Connect the MUT-IIto the diagnosis connector and erase
the diagnosis code.
Caution
Turn the ignition switch to “LOCK”(OFF) position
before connecting or disconnecting the MUT-II.
2. If the MUT-IIbuzzer sounds once when each switch is
operated (ON/OFF), the input signal for that switch circuit
system is normal.
WHEN USING A VOLTMETER
1. Use the special tool to connect the ETACS terminal
(terminal 9) and the earth terminals (terminals 4 and 5)
of the diagnosis connector to the voltage meter.
2. If the needle of the voltage meter flickers once when
each switch is operated (ON/OFF), the input signal for
that switch circuit system is normal.MUT-˜

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 ServiceGENERAL -Precautions Before Service00-19
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.
DEngine coolant temperature: 80 to 90_C
DLamps, electric cooling fan and all accessories: OFF
DM/T: Neutral
DA/T: P range
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.
DSpray nozzle distance: Approx. 40 cm or more
DSpray pressure: 3,900 kPa or less
DSpray temperature: 82_C or less
DTime of concentrated spray to one point: within 30 sec.
