System Description: Notes

Multi AV system means that the following systems are integrated.

SYSTEM REFERENCE

System name	System explanation
AUDIO SYSTEM	SYSTEM DIAGRAM
VEHICLE INFORMATION SYSTEM	Indicates the status of audio, climate control system, fuel economy and maintenance. 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.
HANDS-FREE PHONE SYSTEM	SYSTEM DESCRIPTION
AUXILIARY INPUT SYSTEM	Refer to AUXILIARY INPUT SYSTEM shown below.

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 information. 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 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.

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