DTC CONFIRMATION PROCEDURE
1.PRECONDITIONING
If DTC Confirmation Procedure has been previously conduc ted, always turn ignition switch OFF and wait at
least 10 seconds before conducting the next test.
TESTING CONDITION:
• Before performing the following procedure, confirm th at battery voltage is more than 11 V at idle.
• Always perform the test at a temperature above −12 °C (10 °F)
>> GO TO 2.
2.PERFORM DTC CONFIRMATION PROCEDURE
With CONSULT
1. Turn ignition switch ON.
2. Select “DATA MONITOR” mode with CONSULT.
3. Make sure that “COOLAN TEMP/S” indicates between −12 °C (10 °F) to 59 °C (138 °F).
If not, cool engine down or warm engine up until “COOLAN TEMP/S” indicates between −12 °C (10 °F) to
59 °C (138 °F). Then go to the following steps.
4. Fully release accelerator pedal and wait at least 10 seconds.
5. Depress accelerator pedal and wait at least 10 seconds.
6. Check 1st trip DTC.
With GST
Following the procedure “With CONSULT” above.
Is 1st trip DTC detected?
YES >> Proceed to EC-462, "Diagnosis Procedure".
NO >> INSPECTION END
