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.
NOTE:
Onboard self-diagnosis cannot be started when an error occurs on the dotted-line part above.
SELF-DIAGNOSIS RESULTS
Check the applicable display at the following table, and then repair the malfunctioning parts.
