DIAGNOSIS SYSTEM (AV CONTROL UNIT)

DIAGNOSIS SYSTEM (AV CONTROL UNIT)

Diagnosis Description

INFOID:0000000005528477

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).
