SYSTEM

COMMUNICATION SIGNAL

• AV control unit function by transmitting/receiving data one by one with each unit (slave unit) that configures

them completely as a master unit by connecting between units that configure MULTI AV system with two AV
communication lines (H, L).

• Two AV communication lines (H, L) adopt a twisted pair line that is resistant to noise.
• AV control unit is connected by CAN communication, and it receives data signal from ECM and combination

meter, and computes and displays fuel economy information value with the obtained information. Transmit-
ting/receiving of data signal is performed by BCM. Also, it transmits the required signal of vehicle setting and
receives the response signal.

• AV control unit is connected with display unit and serial communication, and it transmits the required signal

of display and display control and receives the response signal from display unit.

AUDIO FUNCTION

The audio system is equipped with the following functions. Each function is operated with multifunction switch,
preset switch, steering switch. Operation status of audio is indicated at display.

Operating Signal

Audio system operation can be performed with multifunction switch, preset switch or steering switch.
• Operating signal is transmitted to AV control unit with AV communication when it is operated by multifunction

switch or preset switch. The disk ejection operating signal is performed by hardwire.

• Operating signal is transmitted to AV control unit with steering switch signal when it is operated by steering

switch.

Screen Display

• Switching of display is performed with serial communication between display unit and AV control unit.
• The image signal to display operating condition is performed with RGB image signal, RGB area signal and

RGB image synchronizing signal.

AM/FM Radio Mode

• AM/FM radio tuner is built into AV control unit.
• AM/FM radio wave is received by rod antenna, next it is amplified by antenna amp., and finally it is input to

AV control unit. 

• FM radio wave is received by FM sub antenna, and it is transmitted to the AV control unit directly. The FM

sub antenna is installed on the back door window glass.

• AV control unit outputs audio signal to each speaker.

Satellite Radio Mode

• Satellite radio tuner is controlled by communication signal and request signal with AV control unit.
• Sound signal (satellite radio) is received by satellite radio antenna (antenna base) and transmitted to AV

control unit via satellite radio tuner. AV control unit is output the sound signal (satellite radio) to each
speaker.

CD Mode

• CD function is built into AV control unit.
• AV control unit outputs audio signal to each speaker when CD is inserted to AV control unit.

USB Connection Function

• Connecting iPod

®

 or USB memory allows the driver to play iPod

®

 music files or USB memory-stored music

files.

• Sound signals of music files stored in iPod

®

 or USB memory is transmitted from the USB connector to the

AV control unit. The AV control unit transmits the sound signals to the each speaker.

 is a trademark of Apple inc., registered in the U.S. and other countries.

• Image signals cannot be received from iPod

®

 or USB memory.

• Use the enclosed USB harness when connecting iPod

®

 to USB connector.

HANDS-FREE PHONE SYSTEM

• TEL adapter unit is controlled with AV communication from AV control unit.
• The connection between cellular phone and TEL adapter unit is performed with Bluetooth

®

 communication.

• The voice guidance signal is input from the TEL adapter unit to the AV control unit to the front speaker when

operating the cellular phone.

• TEL adapter unit has the on board self-diagnosis function. Refer to 

AV-68, "On Board Diagnosis Function"

.

When A Call Is Originated

• Spoken voice sound output from the microphone (microphone signal) is input to TEL adapter unit. 
• TEL adapter unit outputs to cellular phone with Bluetooth

®

 communication as a TEL voice signal. 

• Voice sound is then heard at the other party.

When Receiving A Call

• Voice sound is input to own cellular phone from the other party. 
• TEL voice signal is input to TEL adapter unit by establishing Bluetooth

®

 communication from cellular phone,

and the signal is output to front speaker.

AUXILIARY INPUT FUNCTION

• Image and sound can be output from an external device by connecting a device with auxiliary input jacks.
• AUX image signals are transmitted to the display unit via the AV control unit, and AUX sound signals are

transmitted to each speaker via the AV control unit.

REAR VIEW MONITOR FUNCTION

Camera Image Operation Principle

• The AV control unit supplies power to the rear view camera when receiving a reverse signal.
• The rear view camera transmits camera images to the AV control unit when power is supplied from the AV

control unit.

• The AV control unit transmits a warning message, fixed guide lines, and predictive course lines to the display

unit by RGB image signals. Rear view monitor images are displayed by combining the RGB image signals
and the camera image signals from the rear view camera.

• Predictive course lines are controlled by a steering angle sensor signal received the AV control unit via CAN

communication.

VEHICLE INFORMATION FUNCTION

• Status of audio, climate control system, fuel economy and maintenance are displayed.
• AV control unit displays the fuel consumption status while receiving data signal through CAN communication

from ECM and combination meter.

• AV control unit is connected to BCM via CAN communication transmitting/receiving for the vehicle settings

function.

DIAGNOSIS SYSTEM (AV CONTROL UNIT)

DIAGNOSIS SYSTEM (AV CONTROL UNIT)

Description

INFOID:0000000009721601

• 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 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 Function

INFOID:0000000009721602

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.

• 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 require human intervention and judgment (the system cannot make judg-
ment automatically).
