System Description

INFOID:0000000003508364

Multi AV system means that the following systems are integrated.

• AV control unit functions 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 the 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.

AUDIO SYSTEM

AV-21, "System Description"

VEHICLE INFORMATION SYSTEM

• Indicates the status of audio, climate control system, fuel econ-

omy and maintenance.

• AV control unit displays the fuel consumption status while re-

ceiving data signal through CAN communication from ECM, uni-
fied meter and A/C amp.

• AV control unit is connected to BCM via CAN communication 

transmitting/receiving for the vehicle settings function.

AUXILIARY INPUT SYSTEM

Refer to “AUXILIARY INPUT SYSTEM” shown below.

AV-18

< FUNCTION DIAGNOSIS >

[BASE AUDIO WITHOUT NAVIGATION]

MULTI AV SYSTEM

• AV control unit is connected by CAN communication, and it receives a data signals from the ECM, unified

meter and A/C amp. It computes and displays fuel economy information values with the obtained informa-
tion. The transmitting/receiving of data signals is performed by the BCM. In addition, it transmits the required
signal of vehicle setting and receives the response signal.

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

the display and the display control and receives the response signal from the front display. Also, it is con-
nected with satellite radio by serial communication, and it transmits the operating signal and receives the
display signal.

NOTE:
AV control unit can perform CONSULT-III self-operating function and on board self-diagnosis.
• CONSULT-III self-diagnosis: refer to 

AV-37, "CONSULT-III Function (MULTI AV)"

.

• On board self-diagnosis: refer to 

AV-28, "Diagnosis Description"

.

AUXILIARY INPUT SYSTEM

• Image and sound can be output from an external device by connecting a device with auxiliary input jacks.
• Operation can be performed by the multifunction switch and steering switch. Multifunction switch transmits

operation signal to AV control unit with communication.

Description

AV CONTROL UNIT

• It is the master unit of the MULTI AV system, and it is connected to each control 

unit by communication. It operates each system according to communication 
signals from AV control unit.

• AV control unit includes audio function and vehicle information function.
• It is connected to ECM and unified meter and A/C amp via CAN communica-

tion to obtain necessary information for the vehicle information function.

• It is connected to BCM via CAN communication transmitting/receiving for the 

vehicle settings function.

• It inputs the illumination signals that are required for the display dimming con-

trol.

• It inputs the signals for driving status recognition (vehicle speed, reverse and 

parking brake). 

• Auxiliary image signal is input from the auxiliary input jacks.
• Camera image signal is input from camera control unit.
• AV control unit recognizes the presence of camera system with camera con-

nection recognition signal.

DISPLAY UNIT

• Display image is controlled by the serial communication from AV control unit.
• RGB image signal is input from AV control unit (RGB, RGB area and RGB syn-

chronizing). 

• Synchronizing signal (HP, VP) is output to AV control unit.
• Composite image signal is input from AV control unit.

FRONT DOOR SPEAKER

• Outputs sound signal from AV control unit.
• Outputs sound (mid and low range).

REAR DOOR SPEAKER

• Outputs sound signal from AV control unit.
• Outputs sound (mid and low range).

FRONT SQUAWKER

• Outputs sound signal from AV control unit.
• Outputs sound (high and mid range).

MULTIFUNCTION SWITCH

• Operation panel is equipped with the centralized switch where audio and aux-

iliary input operations are integrated.

• Connected with preset switch via cable, and operation signal is transmitted to
