DTC CONFIRMATION PROCEDURE
1.PRECONDITIONING
If DTC Confirmation Procedure has been previously conducted, always perform the following procedure before conducting the next test.
>> GO TO 2.
2.CHECK ENGINE COOLANT TEMPERATURE SENSOR FUNCTION
With CONSULT
With GST
Follow the procedure “With CONSULT” above.
Is it above 5В°C (41В°F)? YES >> INSPECTION END
NO >> GO TO 3.
3.PERFORM DTC CONFIRMATION PROCEDURE
With CONSULT
If “COOLANT TEMP/S” indication increases to more than 10°C (50°F) within 65 minutes, stop engine because the test result will be OK.
CAUTION:
Be careful not to overheat engine.
With GST
Follow the procedure “With CONSULT” above.
Is 1st trip DTC detected? YES >> Proceed to EC-203, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis Procedure
1.CHECK ENGINE COOLANT TEMPERATURE SENSOR
Check the engine coolant temperature sensor. Refer to EC-197, "Component Inspection".
Is the inspection result normal? YES >> GO TO 2.
NO >> Replace engine coolant temperature sensor. Refer to CO-24, "Exploded View".
2.CHECK THERMOSTAT OPERATION
When the engine is cold [lower than 70В°C (158В°F)] condition, grasp lower radiator hose and confirm the engine coolant does not flow.
Is the inspection result normal? YES >> Check intermittent incident. Refer to GI-39, "Intermittent Incident".
NO >> Repair or replace thermostat. Refer to CO-21, "Removal and Installation of Thermostat".
Component Inspection
1.CHECK ENGINE COOLANT TEMPERATURE (ECT) SENSOR
Is the inspection result normal? YES >> INSPECTION END
NO >> Replace engine coolant temperature sensor. Refer to CO-24, "Exploded View".
