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.

VEHICLE INFORMATION FUNCTION
• Status of audio, climate control system, fuel economy, maintenance and navigation are displayed.
• AV control unit displays the fuel consumption status while receiving data signal through CAN communication
from ECM, unified meter and A/C amp.
• AV control unit is connected to BCM via CAN communication transmitting/receiving for the vehicle settings
function.

DIAGNOSIS SYSTEM (AV CONTROL UNIT)
On Board Diagnosis Function
INFOID:0000000005475012
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 hazard switch and 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. 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).
