HOW TO DIAGNOSE
GENERAL 00E-10
1. VOLTAGE CHECK
(1) Ground one lead wire of the test light. If a voltmeter is
used instead of the test light, ground the grounding side
lead wire.
(2) Connect the other lead wire of the test light to the power
side terminal of the switch connector. The test light
should come on or the voltmeter should indicate a
voltage.
(3) Then, connect the test light or voltmeter to the motor
connector. The test light should not come on, or the
voltmeter should indicate no voltage. When the switch is
turned ON in this state, the test light should come on, or
the voltmeter should indicate a voltage, with the motor
starting to run.
(4) The circuit illustrated here is normal. If there is any
problem, such as the motor failing to run, check voltages
beginning at the connector nearest to the motor until the
faulty part is identified.
2. SHORT-CIRCUIT CHECK
Because the fuse has blown, it is probable that there is a
short circuit. Follow the procedures below to narrow down
the short-circuit location.
STEP 1. Remove the blown fuse and connect the test light
across the fuse terminals (Circuit switch: OFF).
Q: Does the test light illuminate?
YES : Short-circuit exists between the fuse block and the
switch. Diagnose the harness between the fuse block
and the switch.
NO : Go to Step 2.

ENGINE COOLING DIAGNOSIS

DIAGNOSIS
STEP 1. Measure the power supply voltage at fan
controller connector A-24.
(1) Disconnect fan controller connector A-24 and measure
wiring harness side connector.
(2) Turn the ignition switch to the "ON" position.
(3) Measure the voltage between fan controller connector A-24
terminal 3 and body earth.
The voltage should measure system voltage.
(4) Turn the ignition switch to the "LOCK" (OFF) position.
(5) Connect fan controller connector A-24.
Q: Is the measured voltage system voltage?
YES : Go to Step 17.
NO : Go to Step 2.
STEP 2. Check the fan controller connector A-24.
Q: Is the connector in good condition?
YES : Go to Step 3.
NO : Repair or replace the connector. Then go to Step 24.

STEP 3. Check the fusible link No.2.
Q: Is the fusible link No.2 in good condition?
YES : Go to Step 4.
NO : Replace the fusible link No.2. Then go to Step 24.
STEP 4. Measure the power supply voltage at fan control
relay connector A-10X.
(1) Disconnect fan control relay connector A-10X (remove the
fan control relay) and measure relay box side connector.
(2) Turn the ignition switch to the "ON" position.
(3) Measure the voltage between fan control relay connector
A-10X terminal 4 and body earth.
The voltage should measure system voltage.
(4) Turn the ignition switch to the "LOCK" (OFF) position.
(5) Connect fan control relay connector A-10X (install the fan
control relay).
Q: Is the measured voltage system voltage?
YES : Go to Step 7.
NO : Go to Step 5.

STEP 10. Measure the terminal voltage at fan control relay
connector A-10X.
(1) Disconnect fan control relay connector A-10X (remove the
fan control relay) and measure relay box side connector.
(2) Turn the ignition switch to the "ON" position.
(3) Measure the voltage between fan control relay connector
A-10X terminal 3 and body earth.
The voltage should measure system voltage.
(4) Turn the ignition switch to the "LOCK" (OFF) position.
(5) Connect fan control relay connector A-10X (install the fan
control relay).
Q: Is the measured voltage system voltage?
YES : Go to Step 13.
NO : Go to Step 11.

RADIATOR CAP PRESSURE CHECKM1141001300419
NOTE: Be sure that the cap is clean before testing. Rust or
other foreign material on the cap seal will cause an improper
reading.
1. Use a cap adapter to attach the cap to the tester.
2. Increase the pressure until the indicator of the gauge stops
moving.
Minimum limit: 83 kPa (12 psi)
Standard value: 93
123 kPa (14 18 psi)
3. Replace the radiator cap if the reading does not remain at or
above the limit.
ENGINE COOLANT REPLACEMENTM1141001200478
When removing the radiator cap, use care to avoid
contact with hot coolant or steam. Place a shop towel
over the cap and turn the cap counterclockwise a lit-
tle to let the pressure escape through the vinyl tube.
After relieving the steam pressure, remove the cap by
slowly turning it counterclockwise.
1. Drain the water from the radiator, heater core and engine
after unplugging the radiator drain plug and removing the
radiator cap.

2. Drain the water in the water jacket by unplugging the drain
plug of the cylinder block.
3. Remove the radiator condenser tank assembly and drain the
coolant.
4. Drain the coolant then clean the path of the coolant by
injecting water into the radiator from the radiator cap area.
5. Apply the designated sealant to the screw area of the
cylinder block drain plug, and then tighten to the standard
torque.
Specified sealant: 3M

5 Nm
6. Securely tighten the radiator drain plug.
7. Assemble the radiator condenser tank assembly.
