Circuit Description: Notes
WARNING: This page is about a different car, the 2003 Lexus LS 430. However, it is still accessible from the selected car via links, so may be relevant.
Each unit of the LEXUS navigation system connected with AVC-LAN (communication bus) transmits a signal of each switch.
When +B short or GND short occurs in this AVC-LAN, the LEXUS navigation system will not function normally as the communication is discontinued.
In this AVC-LAN, the radio and player becomes the master of the communication, having a resistance necessary for transmitting the signals.
