OVERVIEW
The vehi cl e elect rical s ys t em compri s es a number of control modul es which are int erconnected vi a s everal net works ys t ems .
The fol lowing net work sys tems are us ed on t he vehi cle:
High Speed Controll er Area Network busMedium speed CAN busLocal Int erconnect Network (LIN) busMedia O rient ated Sys tems Transport (MOST) s yst em.
The CJB is the 'gat eway' for the net work s yst ems whi ch allows informati on to be exchanged bet ween networks .
The entertainment s yst em components are connected on a fi ber opt ic MO ST sys t em. The MOST s ys t em can s end andreceive i nformat ion to/from t he other network s ys t ems via a 'gat eway' in the Integrat ed Control Modul e.
The fol lowing table shows each vehi cle control modul e, t he network s yst em to whi ch it i s connected, it s funct ion andlocati on in the vehicle.
