• The AV control unit diagnosis function starts up with multifunction switch operation and the AV control unit

• Perform a CONSULT diagnosis if the on board diagnosis does not start, e.g., the screen does not display

anything, the multifunction switch does not function, etc.

INFOID:0000000009471442

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 “UP” 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.

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. 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 make judg-

ment automatically).

1. Start the self-diagnosis function and select “Self Diagnosis”.

Self-diagnosis subdivision screen is displayed, and the self-diagnosis mode starts.

The bar graph visible on the center of the self-diagnosis subdivision screen indicates progress of the trou-

ble diagnosis.

pleted. The unit names and the connection lines are color-coded

according to the diagnostic results.

NOTE:
Control unit (AV control unit) and amplifier (BOSE amp.) are 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.

• If multiple errors occur at the same time for a single unit, the screen switch colors are determined according 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.

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.
