Refer to
DTC CONFIRMATION PROCEDURE
1.
PRECONDITIONING
• Turn power switch OFF and wait at least 90 seconds.
CAUTION:
During this period, never perform vehicle handling such as opening and closing of doors. If some
kind of vehicle handling is performed, then wait another 90 seconds or more from the time of the
vehicle handling.
• Make sure that 12V battery voltage is 11 V or more.
>> GO TO 2.
2.
PERFORM DTC CONFIRMATION PROCEDURE
With CONSULT
1. Turn power switch ON at least 10 seconds.
2. Check self-diagnostic result.
Is DTC detected?
YES
>> Proceed to
EVC-193, "Diagnosis Procedure"
NO
