SELF–DIAGNOSIS RESULTS
Operation Procedure

1.

Touch “AUTO DRIVE POSITIONER” on “SELECT TEST ITEM” screen.

2.

Touch “SELF–DIAG RESULTS” on “SELECT DIAG MODE” screen.

3.

Touch “START” on “SELF–DIAG RESULTS” screen.

4.

The seat and steering wheel automatically move, and the self-diagnosis for the seat, steering wheel and
door mirror start (door mirror does not operate).

5.

Within 15 seconds after the self-diagnosis for the seat, steering wheel and door mirror are completed,
drive the vehicle at a speed of 7 km/h (4 MPH) or higher for the vehicle speed sensor self-diagnosis.

6.

After the diagnosis is completed, the malfunctioning system is displayed.

7.

When the malfunctioning items are displayed, touch “COPY” to record.

8.

Touch “ERASE”.

9.

Perform self-diagnosis results again to check that any malfunctioning item is displayed.

10. Check the displayed items.
