Check the coolant level in the reservoir tank and radiator.
Allow engine to cool befo
re checking coolant level.
Is the coolant level in the reservoir tank and/or radiator below the
proper range?
YES >> Go to EC-373, "Diagnosis Procedure".
NO >> GO TO 2.
2.PERFORM COMPONENT FUNCTION CHECK-II
Confirm whether customer filled the coolant or not.
Did customer fill the coolant?
YES >> Go to EC-373, "Diagnosis Procedure".
NO >> GO TO 3.
3.PERFORM COMPONENT FUNCTION CHECK-III
With CONSULT-III
1. Turn ignition switch ON.
2. Perform “COOLING FAN” in “ACTIVE TEST” mode with CONSULT-III.
3. Make sure that cooling fan motor operates at each speed (LOW/HI).
Without CONSULT-III
Perform IPDM E/R auto active test and check cooling fan motor operation. Refer to PG-20, "
Auto Active Test".
Is the inspection result normal?
YES >> INSPECTION END
NO >> Go to EC-373, "
Diagnosis Procedure".

7.CHECK MAIN 12 CAUSES
If the cause cannot be isolated, check the following.
*1: Turn the ignition switch ON.
*2: Engine running at 3,000 rpm for 10 minutes.
*3: Drive at 90 km/h (56 MPH) for 30 minutes and then let idle for 10 minutes.
*4: After 60 minutes of cool down time.
For more informat ion, refer to CO-7, "
Troubleshooting Chart".

COOLING FAN
DescriptionINFOID:0000000005930111
The ECM controls the cooling fan corresponding to the vehicle speed, engine coolant
temperature, refrigerant
pressure, and air conditioner ON signal. The contro l system has 3-step control [HIGH/LOW/OFF].
COOLING FAN MOTOR
Models without A/C
The cooling fan operates at each speed when the current flows in the cooling fan motor as per the following.
Models with A/C
The cooling fan operates at high (HI) speed when the current flows, and operates at low (LOW) speed when
cooling fan motor and the resistor are circuited in series.
Component Function CheckINFOID:0000000005930112
1.CHECK COOLING FAN FUNCTION
With CONSULT-III
1. Turn ignition switch ON.
2. Perform “COOLING FAN” in “ACTIVE TEST” mode with CONSULT-III.
3. Touch “LOW” and “Hi” on the CONSULT-III screen.
4. Check that cooling fan operates at each speed.
Without CONSULT-III
1. Perform IPDM E/R auto active test and c heck cooling fan motor operation. Refer to PG-20, "
Auto Active
