AVC-LAN Circuit (Multi-Display Controller - Radio Receiver)
AVC-LAN CIRCUIT (MULTI-DISPLAY CONTROLLER SUB-ASSY - RADIO RECEIVER ASSYCIRCUIT DESCRIPTION
Each unit of the navigation system connected to AVC-LAN (communication bus) communicates by transferring the signals from each switch.
When +B short and GND short occur in this AVC-LAN, navigation system will not function normally as communication is discontinued.
In AVC-LAN, multi-display becomes the communication master, and the radio receiver assy has enough resistance necessary for transmitting the communication.
