DTC Description
DTC DETECTION 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.

DTC CONFIRMATION PROCEDURE
1.CHECK DTC PRIORITY
If DTC P1217 is displayed with DTC UXXXX or P0607, first perform the trouble diagnosis for DTC UXXXX or P0607.
Is applicable DTC detected? YES >> Perform diagnosis of applicable. Refer to EC-93, "DTC Index".
NO >> GO TO 2.
2.PERFORM COMPONENT FUNCTION CHECK-1
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.
Is the coolant level in the reservoir tank and/or radiator below the proper range? YES >> Proceed to EC-398, "Diagnosis Procedure".
NO >> GO TO 3.
3.PERFORM COMPONENT FUNCTION CHECK-2
Confirm whether customer filled the coolant or not.
Did customer fill the coolant? YES >> Proceed to EC-398, "Diagnosis Procedure".
NO >> GO TO 4.
4.PERFORM COMPONENT FUNCTION CHECK-3
With CONSULT
Is the inspection result normal? YES >> INSPECTION END
NO >> Proceed to EC-398, "Diagnosis Procedure".
Diagnosis Procedure
1.CHECK DTC PRIORITY
If DTC P1217 is displayed with DTC UXXXX or P0607, first perform the trouble diagnosis for DTC UXXXX or P0607.
Is applicable DTC detected? YES >> Perform diagnosis of applicable. Refer to EC-93, "DTC Index".
NO >> GO TO 2.
2.CHECK COOLING FAN OPERATION
With CONSULT
Is the inspection result normal? YES >> GO TO 3.
NO >> Proceed to EC-458, "Diagnosis Procedure".
3.CHECK COOLING SYSTEM FOR LEAK-1
Check cooling system for leak. Refer to CO-8, "Inspection".
Is leakage detected? YES >> GO TO 4.
NO >> GO TO 5.
4.CHECK COOLING SYSTEM FOR LEAK-2
Check the following for leak.
>> Repair or replace malfunctioning part.
5.CHECK RADIATOR CAP
Check radiator cap. Refer to CO-12, "RADIATOR CAP : Inspection".
Is the inspection result normal? YES >> GO TO 6.
NO >> Replace radiator cap. Refer to CO-13, "Exploded View".
6.CHECK THERMOSTAT
Check thermostat. Refer to CO-21, "Removal and Installation".
Is the inspection result normal? YES >> GO TO 7.
NO >> Replace thermostat. Refer to CO-21, "Removal and Installation".
7.CHECK ENGINE COOLANT TEMPERATURE SENSOR
Refer to EC-212, "Component Inspection".
Is the inspection result normal? YES >> GO TO 8.
NO >> Replace engine coolant temperature sensor. Refer to CO-23, "Exploded View".
8.OVERHEATING CAUSE ANALYSIS
If the cause cannot be isolated, check the CO-6, "Troubleshooting Chart".
