• 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.
• AV control unit is connected by CAN communication, and it receives 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 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 of

display and display control and receives the response signal from front display. Also, it is connected with sat-
ellite 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-201, "CONSULT-III Function (MULTI AV)"

.

• On board self-diagnosis: refer to 

AV-192, "Diagnosis Description"

.

On board self-diagnosis of TEL adapter unit can be performed.
• Refer to 

AV-205, "Diagnosis Description"

 for on board self-diagnosis.

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 with 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 display dimming control.
• 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.

BOSE AMP.

• Inputs power (amp. ON) and sound signal from AV control unit, and outputs 

sound signal to woofer and each speaker.

• Input “Driver's Audio Stage” mode change signal from AV control unit. 
• Woofer amp. ON signal is transmitted to woofer.
