sound signal to BOSE amp., and BOSE amp. output sound signal to woofer and each speaker.
• Receiving/transmitting of iPod
®
operation signals are performed as follows:
- between AV control unit and iPod adapter: AV communication.
- between iPod
®
and iPod adapter: serial communication.
• The iPod
®

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 the ignition switch is turned 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., if the screen does not dis-
play 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.
• Self-diagnosis mode performs the AV control unit diagnosis and the connection diagnosis between each of
the units that make up the system, and it indicates the results to 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 requires human intervention and judgment (the system cannot make judg-
ment automatically).

DIAGNOSIS SYSTEM (AV CONTROL UNIT)
1.
Start the self-diagnosis function and select “Self-diagnosis”.
NOTE:
Because the start condition of diagnosis function is a switch
operation, the on board diagnosis function cannot start up if any
malfunction is detected in the AV communication circuit between
AV control unit and multifunction switch.
-
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 progress of the trouble 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:
• 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 AV con-
trol unit internal error. Refer to
-
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
Check the applicable display at the following table, and then repair the malfunctioning parts.
NOTE:
Because the start condition of diagnosis function is a switch operation, the on board diagnosis function cannot
be started up if any malfunction is detected in the AV communication circuit between AV control unit and multi-
function switch.
