Its Communication

WARNING: This page is about a different car, the 2012 Infiniti M35h. However, it is still accessible from the selected car via links, so may be relevant.

ITS communication is a multiplex communication system. This enables the system to transmit and receive large quantities of data at high speed by connecting control units with 2 communication lines.
ITS communication lines adopt twisted-pair line style (two lines twisted) for noise immunity.
