Each unit of this 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, this system will not function normally as communication is discontinued.
This system has 2 kinds of AVC-LAN: main AVC-LAN and sub AVC-LAN.
with navigation system:
In the main AVC-LAN, the radio and navigation assembly becomes the communication master and has enough resistance necessary for communication.
with out navigation system:
In the main AVC-LAN, the radio receiver assembly becomes the communication master and has enough resistance necessary for communication.
In the sub AVC-LAN, the multi-display controller sub-assembly becomes the communication master and has enough resistance necessary for
communication.
