P1217 Engine Over TemperatureOn Board Diagnosis 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.
This self-diagnosis has the one trip detection logic.
P1217:
CAUTION: When a malfunction is indicated, always replace the coolant. Refer to [Changing Engine Coolant]. Service and Repair Also, replace the engine oil.
1. Fill radiator with coolant up to specified level with a filling speed of 2 liters per minute. Always use coolant with the proper mixture ratio. Refer to [Recommended Fluids and Lubricants]. Fluid Type Specifications
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 engine coolant over temperature enrichment protection 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 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 SDT
1. Check the coolant level in the reservoir tank and radiator.
NOTE: 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 [P1217 Engine Over Temperature].
2. Confirm whether customer filled the coolant or not. If customer filled the coolant, skip the following steps and go to [P1217 Engine Over Temperature].
3. Start engine.
4. Make sure that cooling fan (crankshaft driven) operates.
5. If NG, go to [P1217 Engine Over Temperature].
WITH GST
1. Check the coolant level in the reservoir tank and radiator.
NOTE: 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 [P1217 Engine Over Temperature].
2. Confirm whether customer filled the coolant or not. If customer filled the coolant, skip the following steps and go to [P1217 Engine Over Temperature].
3. Start engine and make sure that cooling fan (crankshaft driven) operates.
CAUTION: Be careful not to overheat engine.
4. If NG, go to [P1217 Engine Over Temperature].
