P1217

P1217 ENGINE OVER TEMPERATURE





On Board Diagnosis Logic

NOTE:
- If DTC P1217 is displayed with DTC UXXXX, first perform the trouble diagnosis for DTC UXXXX.
- If DTC P1217 is displayed with DTC P0607, first perform the trouble diagnosis for DTC P0607. P0607 P0607 P0607 P0607.
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.
This self-diagnosis has the one trip detection logic.









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 and/or reservoir tank cap when the engine is hot. Serious burns could be caused by high pressure fluid escaping from the radiator and/or reservoir tank.
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 Diagnosis Procedure.
2. Confirm whether customer filled the coolant or not. If customer filled the coolant, skip the following steps and go to Diagnosis 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 Diagnosis Procedure.

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 Diagnosis Procedure.
2. Confirm whether customer filled the coolant or not. If customer filled the coolant, skip the following steps and go to Diagnosis Procedure.
3. Disconnect engine coolant temperature sensor harness connector.
4. Connect 150 Ohm(s) resistor to engine coolant temperature sensor harness connector.





5. Start engine and make sure that cooling fan operates.

CAUTION:
Be careful not to overheat engine.
6. If NG, go to Diagnosis Procedure.




Diagnosis Procedure
1.CHECK COOLING FAN (CRANKSHAFT DRIVEN) OPERATION
1. Start engine and let it idle.
2. Make sure that cooling fan (crankshaft driven) operates normally.
OK or NG
OK (With CONSULT-III)-GO TO 2.
OK (Without CONSULT-III)-GO TO 3.
NG - Check cooling fan (crankshaft driven). Removal and Installation.
2.CHECK COOLING FAN MOTOR OPERATION
With CONSULT-III
1. Start engine and let it idle.
2. Select "COOLING FAN" in "ACTIVE TEST" mode with CONSULT-III.
3. Make sure that cooling fan operates.
OK or NG
OK - GO TO 4.
NG - Check cooling fan control circuit. (Go to "PROCEDURE A".)
3.CHECK COOLING FAN MOTOR OPERATION
Without CONSULT-III
1. Disconnect engine coolant temperature sensor harness connector.
2. Connect 150 Ohm(s) resistor to engine coolant temperature sensor harness connector.
3. Start engine and let it idle.





4. Make sure that cooling fan operates.
OK or NG
OK - GO TO 4.
NG - Check cooling fan control circuit. (Go to "PROCEDURE
A".)
4.CHECK COOLING SYSTEM FOR LEAK
Inspection.
OK or NG
OK - GO TO 5.
NG - Check the following for leak.
- Hose
- Radiator
- Radiator cap
- Water pump
- Reservoir tank
5.CHECK COMPONENT PARTS
Check the following.
- RESERVOIR TANK CAP ( Inspection.)
- Thermostat. ( Removal and Installation.)
- Engine coolant temperature sensor. ( P0117.)
OK or NG
OK - GO TO 6.
NG - Replace malfunctioning component.
6.CHECK MAIN 13 CAUSES
If the cause cannot be isolated, go to P1217.
