The name MULTIFUNCTION SWITCH indicates the integration of PRESET SWITCH and MULTIFUNCTION
SWITCH virtually.

System Description

INFOID:0000000000964625

Multi AV system means that the following systems are integrated.

• AV control unit controls by sending/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 com-
munication 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, unified meter

and A/C amp. It computes and displays fuel economy information value with the obtained information. Send-
ing/receiving of data signal is performed by BCM. Also, it sends the required signal of vehicle setting and
receives the response signal.

• AV control unit is connected with display and serial communication, and it sends the required signal of dis-

play and display control and receives the response signal from front display. Also, it is connected with satel-
lite radio by serial communication, and it sends the operating signal and receives the display signal.
