MULTI AV SYSTEM

System Diagram

INFOID:0000000001559117

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

System Description

INFOID:0000000001559118

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 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, unified meter

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