AVC-LAN Circuit (Multi-Display - Gateway ECU)

AVC-LAN CIRCUIT (MULTI-DISPLAY - GATEWAY ECU)

CIRCUIT DESCRIPTION
Each unit of the audio system connected to the AVC-LAN (communication bus) communicates by transferring the signals from each switch.

When a short to +B or short to ground occurs in this AVC-LAN, the audio system will not function normally as communication is discontinued.

In this AVC-LAN, the multi display becomes the communication master, and the radio receiver assembly has enough resistance necessary for communication.
