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.

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".
