DTC CONFIRMATION PROCEDURE
1.
PRECONDITIONING
If DTC Confirmation Procedure has been previously conducted, always perform the following procedure
before conducting the next test.
1.
Turn ignition switch OFF and wait at least 12 minutes.
2.
Turn ignition switch ON.
3.
Turn ignition switch OFF and wait at least 12 minutes.
>> With consult: GO TO 2.
>> Without consult: GO TO 3.
2.
PERFORM DTC CONFIRMATION PROCEDURE-1
With CONSULT
1.
Start the engine and warm it up to normal operating temperature.
2.
Press start/stop OFF switch and check that the switch indicator is ON.
3.
Select “AUTO STOP START” in “ACTIVE TEST” mode of “ENGINE” using CONSULT.
