DIAGNOSIS SYSTEM (AV CONTROL UNIT)
NOTE:
*: On-board self-diagnosis is not supported. Only CONSULT-III is supported.
STARTING PROCEDURE
1. Start the engine.
2. Turn the audio system OFF.
3. While pressing the “SETTING” button, turn the volume control
dial clockwise or counterclockwise for 40 clicks or more. (When
the self-diagnosis mode is started, a short beep will be heard.)
 Shifting from current screen to previous screen is performed
by pressing “BACK” button.

displayed. When the malfunctioning item is selected, the time and place
that the selected malfunction last occurred are displayed.
Camera Cont.The signal connected to camera control unit can be checked and the
guiding line position that overlaps rear view camera image can be adjust-
ed.

4. The trouble diagnosis initial screen is displayed, and then the
items of “Self Diagnosis” and “Confirmation/Adjustment” can be
selected.
SELF-DIAGNOSIS MODE
1. Start the self-diagnosis function and select “Self Diagnosis”.
- Self-diagnosis subdivision screen is displayed, and the self-diagnosis mode starts.
- The bar graph visible on the center of the self-diagnosis subdivision screen indicates progress of the trou-
ble diagnosis.
2. Diagnosis results are displayed after the self-diagnosis is com-
pleted. The unit names and the connection lines are color-coded
according to the diagnostic results.
NOTE:
 In case of connection malfunction of GPS or TEL antenna, diagnosis result follows “unit malfunction”
way to display.
 Replace AV control unit if “Self-Diagnosis did not run because of a control unit malfunction” is indicated.
The symptom is AV control unit internal error. Refer to AV-648, "
Exploded View".
- The comments of the self-diagnosis results can be viewed with a
component in the diagnosis result screen.
SELF-DIAGNOSIS RESULTS
 Check the applicable display at the following table, and then repair the malfunctioning parts.
 The self-diagnosis mode allows the technician to diagnose the connection in the communication line
between AV control unit and each unit and the internal operation of the AV control unit.
 Because the start condition of diagnosis function is a switch operation, the on board diagnosis function can-
not be started up if any malfunction is detected in the communication circuit between AV control unit and
multifunction switch.
