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.

Detection range of self-diagnosis mode

• 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.
