AVC-LAN Circuit |
DESCRIPTION
Each unit of the navigation system connected to the AVC-LAN (communication bus) transfers switch signals through 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.
