AVC-LAN CIRCUIT (MULTI-DISPLAY CONTROLLER SUB-ASSY -RADIO RECEIVER ASSY)

CIRCUIT DESCRIPTION
Each unit of the audio system connected to the AVC-LAN (communication bus) transfers the signal of each switch by communication.

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

In this AVC-LAN, the radio receiver assy becomes the master of the communication, and the radio receiver assy has a resistance necessary for transmitting the communication.
