AVC-LAN Circuit
DESCRIPTION
Each unit of the navigation system connected to the AVC-LAN (communication bus)
transfers the switch signals using the AVC-LAN.
If a short to +B or short to ground occurs in the AVC-LAN, the navigation system
will not function normally because communication is not possible.
