Sonar Buzzer Operation

• Each sonar sensor transmits a sensor signal to the sonar control unit when detecting an obstacle.
• The sonar control unit converts a signal received from each sonar sensor into distance and transmits detec-

tion distance signal to the AV control unit via AV communication.

• The AV control unit transmits a buzzer signal to the BOSE amp. corresponding to each sonar sensor based

on the received signal.

• When receiving a buzzer signal, the BOSE amp. transmits the buzzer signal to the each speaker. When

each speaker receives a buzzer signal, a buzzer sounds.

• When the front corner sensor detects an obstacle, a buzzer is heard from the speakers on the front side.
• When the rear corner sensor detects an obstacle, a buzzer is heard from the speakers on the rear side.
• It changes the buzzer cycle in 3 stages according to the detection distance.

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. 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).

DIAGNOSIS SYSTEM (AV CONTROL UNIT)

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-

pleted. The unit names and the connection lines are color-coded
according to the diagnostic results.

NOTE:

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 control unit internal error.
Refer to

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.
