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 subdivi-
sion screen indicates the progress of the trouble diagnosis.

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:
• Only the control unit (AV control unit) is displayed in red.
• Replace AV control unit if “Self-Diagnosis did not run because of a control unit malfunction” is indicated. The symptom is an AV
control unit internal error.
-
If multiple errors occur at the same time for a single unit, the screen switch colors are determined accord-
ing to the following order of priority: red > gray.
-
The comments of the self-diagnosis results can be viewed with a
component in the diagnosis result screen.
SELF-DIAGNOSIS RESULTS
• The self-diagnosis mode allows the technician to diagnose the connection in the communication line
between the AV control unit and each unit, and the internal operation of AV control unit.
• Because the start condition of the diagnosis function is a switch operation, the on board diagnosis function
cannot be started up if any malfunction is detected in the communication circuit between AV control unit and
multifunction switch.
• Check the applicable display in the following table, and then repair the malfunctioning parts.
