Camera Image Operation Principle
If the information writing to around view monitor control unit and the information from the camera are not
matched, the applicable camera position is indicated as an error on the Birds-Eye view display. (Calibration
operation is necessary when replacing each camera or when replacing around view monitor control unit.)
Around view monitor control unit receives the camera switch signal from AV control unit via AV communica-
tion by pressing the “CAMERA” switch of multifunction switch.
Around view monitor control unit that receives the ca mera switch signal supplies the power to each camera
and inputs the camera image from each camera.
When the selector lever is in the reverse position, around view monitor control unit receives the reverse sig- nal, supplies the power to each camera, and inputs the camera image from each camera.
Around view monitor control unit that receives the camera image signal from each camera cuts out the
required screen for each view, superimposes the camera image, vehicle icon, guiding lines, sonar indicator,
and outputs them to the front display unit.
CAMERA ASSISTANCE SONAR FUNCTION
Install the corner sensor on the front bumper and r ear bumper. It detects the obstacles around the vehicle
when the around view monitor is displayed. It warn s of the approach to the obstacles with the buzzer and
indicator in the display linked with the around view monitor system.
It displays the distance between the bumper and obstacle with the color of sonar indicator in the display and the blinking cycle of indicator in 3 stages.
The buzzer warns of the distance to the obstacles with the cycle in 3 stages.
System Operation Description
Around view monitor control unit transmits the sonar operation signal via AV communication to sonar control
unit to control the operation of sonar indicator and sonar buzzer.
Sonar control unit that receives the sonar operation signal from around view monitor control unit transmits
the detection signal and detection distance signal according to the signal from corner sensor via AV commu-
nication to around view monitor control unit. Around vi ew monitor control unit operates the applicable sonar
indicator.
When receiving a sonar operation signal from the around view monitor control unit, the sonar control unit
converts a signal transmitted from the corner sensor into a detection distance signal and transmits it to the
AV control unit via AV communication. When receivi ng the detection signal, the AV control unit activates
each speaker via BOSE amp.

When the light switch is in the 1st or 2nd position, the dimming of the display is judged according to a dimming
signal transmitted from BCM to the AV control unit. Dis play illuminance is independent of vehicle exterior illu-
minance detected by the auto light detecting sensor ev en when the light switch is in 1st or 2nd position.

DIAGNOSIS SYSTEM (AV CONTROL UNIT)
DescriptionINFOID:0000000006216218
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 Diagn osis FunctionINFOID:0000000006216219
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.
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 contro l 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 erro r records and system communication status. The checking,
modifying or adjusting generally require human inte rvention and judgment (the system cannot make judg-
ment automatically).
