Diagnosis Procedure

  1. CHECK COOLING FAN OPERATION

    With CONSULT 

    1. Turn ignition switch ON.
    2. Perform "COOLING FAN" in "ACTIVE TEST" mode with CONSULT.
    3. Make sure that cooling fan motor operates at each speed (LOW/HI).

    Without CONSULT 

    1. Perform IPDM E/R auto active test and check cooling fan motor operation. Refer to "DIAGNOSIS DESCRIPTION ".
    2. Make sure that cooling fan motor operates at each speed (Low/High).

      Is the inspection result normal? 

      YES >> GO TO 2.

      NO >> Go to "DIAGNOSIS PROCEDURE ".

  2. CHECK COOLING SYSTEM FOR LEAK-I

    Check cooling system for leak. Refer to "INSPECTION ".

    Is leakage detected? 

    YES >> GO TO 3.

    NO >> GO TO  4.

  3. CHECK COOLING SYSTEM FOR LEAK-II

    Check the following for leak.

  4. CHECK RADIATOR CAP

    Check radiator cap. Refer to "RADIATOR CAP: INSPECTION ".

    Is the inspection result normal? 

    YES >> GO TO 5.

    NO >> Replace radiator cap. Refer to "EXPLODED VIEW ".

  5. CHECK THERMOSTAT

    Check thermostat. Refer to "INSPECTION ".

    Is the inspection result normal? 

    YES >> GO TO 6.

    NO >> Replace thermostat. Refer to "REMOVAL AND INSTALLATION ".

  6. CHECK WATER CONTROL VALVE

    Check water control valve. Refer to "WATER CONTROL VALVE ".

    Is the inspection result normal? 

    YES >> GO TO 7.

    NO >> Replace water control valve. Refer to "EXPLODED VIEW ".

  7. CHECK ENGINE COOLANT TEMPERATURE SENSOR

    Refer to "COMPONENT INSPECTION ".

    Is the inspection result normal? 

    YES >> GO TO 8.

    NO >> Replace engine coolant temperature sensor. Refer to "EXPLODED VIEW ".

  8. CHECK MAIN 12 CAUSES

    If the cause cannot be isolated, check the following.
