Cooling Fan Relay Operation

COMPONENT DESCRIPTION

Cooling Fan Motor

The cooling fan operates at low (LOW) speed when cooling fan motors -1 and -2 are circuited in series under middle speed condition.

CONSULT-III Reference Value in Data Monitor Mode

On Board Diagnosis Logic

CAUTION: When a malfunction is indicated, be sure to replace the coolant.

1. Fill radiator with coolant up to specified level with a filling speed of 2 liters per minute. Be sure to use coolant with the proper mixture ratio. Refer to "Recommended Fluids and Lubricants".
2. After refilling coolant, run engine to ensure that no water-flow noise is emitted.

Overall Function Check
Use this procedure to check the overall function of the cooling fan. During this check, a DTC might not be confirmed.

WARNING: Never remove the radiator cap when the engine is hot. Serious burns could be caused by high pressure fluid escaping from the reservoir tank or the radiator.
Wrap a thick cloth around cap. Carefully remove the cap by turning it a quarter turn to allow built-up pressure to escape. Then turn the cap all the way off.

WITH CONSULT-III

1. Check the coolant level in the reservoir tank and radiator.
Allow engine to cool before checking coolant level.
If the coolant level in the reservoir tank and/or radiator is below the proper range, skip the following steps and go to "Diagnostic Procedure" below.

2. Confirm whether customer filled the coolant or not. If customer filled the coolant, skip the following steps and go to "Diagnostic Procedure"
3. Turn ignition switch ON.
4. Perform "COOLING FAN" in "ACTIVE TEST" mode with CONSULT-III.
5. If the results are NG, go to "Diagnostic Procedure" below.

WITH GST

1. Check the coolant level in the reservoir tank and radiator.
Allow engine to cool before checking coolant level.
If the coolant level in the reservoir tank and/or radiator is below the proper range, skip the following steps and go to "Diagnostic Procedure" below.

2. Confirm whether customer filled the coolant or not. If customer filled the coolant, skip the following steps and go to "Diagnostic Procedure" below.
3. Perform IPDM E/R auto active test and check cooling fan motor operation. Refer to PG-20, "Auto Active Test" Auto Active Test
4. If NG, go to "Diagnostic Procedure" below.
