DTC CONFIRMATION PROCEDURE

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.

PERFORM DTC CONFIRMATION PROCEDURE

With CONSULT

1. Turn power switch OFF.

2. Connect EVSE.

3. Press the charge connector lock switch at the “LOCK” position. (Check that the charge connector lock is

operating.)

4. Press the charge connector lock switch at the “OFF” position.

5. Disconnect EVSE.

6. Turn power switch ON and wait at least 5 seconds.

7. Check DTC.
Is DTC detected?
