Diagnosis Description
INFOID:0000000005528695
MULTIFUNCTION SWITCH AND PRESET SWITCH SELF-DIAGNOSIS FUNCTION
The ON/OFF operation (continuity) of each switch in the multifunction switch and preset switch can be
checked.
Self-diagnosis Mode
• Press the “BACK” switch and the “
” switch of the 8-direction
switches within 10 seconds after turning the ignition switch from
OFF to ACC and hold them for 3 seconds or more. Then the
buzzer sounds, all indicators of the preset switch illuminate, and
the self-diagnosis mode starts.
• The continuity of each switch at the ON position can be checked
by pressing the switch. The buzzer sounds if the switch is normal.
NOTE:
The disk eject switch cannot be checked.
Finishing Self-diagnosis Mode
Self-diagnosis mode is canceled when turning the ignition switch OFF.
MULTI AV SYSTEM ON BOARD DIAGNOSIS FUNCTION
• The AV control unit diagnosis function starts up with multifunction switch operation and the AV control unit
performs a diagnosis for each unit in the system during the on board diagnosis.
• Perform a CONSULT-III diagnosis if the on board diagnosis does not start, e.g., the screen does not display
anything, the multifunction switch does not function, etc.
ON BOARD DIAGNOSIS
Description
• The trouble diagnosis function has a self-diagnosis mode for conducting trouble diagnosis automatically and
a confirmation/adjustment mode for operating manually.
• The self-diagnosis mode performs diagnoses on the AV control unit, connections between system compo-
nents as well as connections between AV control unit and GPS antenna and between AV control unit and
satellite radio antenna. Then it displays the diagnosis results on the display.
• The confirmation/adjustment mode allows the technician to check, modify or adjust the vehicle signals and
set values, as well as to monitor the system error records and system communication status. The checking,
modifying or adjusting generally require human intervention and judgment (the system cannot automati-
cally).

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 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.
• Check the applicable display at the following table, and then repair the malfunctioning parts.
