2.PERFORM DTC CONFIRMATION PROCEDURE
With CONSULT
If not, cool engine down or warm engine up until “COOLANT TEMP/S” indicates between −7В°C (19В°F) to 60В°C (140В°F). Then go to the following steps.
With GST
Following the procedure “With CONSULT” above.
Is 1st trip DTC detected? YES >> Proceed to EC-413, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis Procedure
