DTC DETECTION LOGIC
NOTE:
Refer to EC-161, "DTC Logic".
If the cooling fan or another component in the cooling system malfunctions, engine coolant temperature will rise.
When the engine coolant temperature reaches an abnormally high temperature condition, a malfunction is indicated.
CAUTION: When a malfunction is indicated, always replace the coolant. Refer to CO-10, "System Inspection".
Also, replace the engine oil. Refer to MA-23, "ENGINE OIL : Changing Engine Oil".
DTC CONFIRMATION PROCEDURE
1.PERFORM COMPONENT FUNCTION CHECK
Perform component function check. Refer to EC-406, "Component Function Check".
NOTE: Use component function check to check the overall function of the cooling fan. During this check, a DTC might not be confirmed.
Component Function Check
1.PERFORM COMPONENT FUNCTION CHECK-I
WARNING: Never remove the radiator cap when the engine is hot. Serious burns could be caused by high pressure fluid escaping from 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.
Check the coolant level in the reservoir tank and radiator.
Allow engine to cool before checking coolant level.
2.PERFORM COMPONENT FUNCTION CHECK-II
Confirm whether customer filled the coolant or not.
3.PERFORM COMPONENT FUNCTION CHECK-III
With CONSULT
Without CONSULT
Perform IPDM E/R auto active test and check cooling fan motors operation
Diagnosis Procedure
1.CHECK COOLING FAN OPERATION
With CONSULT
Without CONSULT
2.CHECK COOLING SYSTEM FOR LEAKAGE-I
Check cooling system for leakage
3.CHECK COOLING SYSTEM FOR LEAKAGE-II
Check the following for leakage.
4.CHECK RADIATOR CAP
Check radiator cap
5.CHECK THERMOSTAT
Check thermostat.
6.CHECK ENGINE COOLANT TEMPERATURE SENSOR
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
