AVC-LAN Circuit (Radio and Navigation Assy - Multi-Display Controller Sub-Assy)

AVC-LAN CIRCUIT (RADIO AND NAVIGATION ASSEMBLY - MULTI-DISPLAY CONTROLLER SUB-ASSEMBLY)

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 communication is discontinued.

In this AVC-LAN, the radio and navigation assembly becomes the master of the communication and has resistance necessary for communication.
