CAN Communication System Description
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle multiplex communication line with high data communication speed and excellent error detection ability.

Many electronic control units are equipped onto a vehicle and each control unit shares information and links with other control units during operation (not independent).

In CAN communication control units are connected with 2 communication lines (CAN H line CAN L line) allowing a high rate of information transmission with less wiring. Each control unit transmits/receives data but selectively reads required data only.
