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 5C (41F)?
YES >> INSPECTION END
NO >> GO TO 3.
3.PERFORM DTC CONFIRMATION PROCEDURE
With CONSULT
If "COOLAN TEMP/S" indication increases to more than 10C (50F) 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, "Diagnosis Procedure".
NO >> INSPECTION END
1.CHECK ENGINE COOLANT TEMPERATURE SENSOR
Check the engine coolant temperature sensor. Refer toEC, "Component Inspection".
Is the inspection result normal?
YES >> GO TO 2.
NO >> Replace engine coolant temperature sensor. Refer to CO, "Exploded View".
2.CHECK THERMOSTAT OPERATION
When the engine is cold [lower than 70C (158F)] 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, "Intermittent Incident".
NO >> Repair or replace thermostat. Refer to CO, "Removal and Installation".
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, "Exploded View".
