DESCRIPTION
CAN (Controller Area Network) is a serial communication line for real time applications. It is an on-Nissan Sentra vehicle multiplex communication line with high data communication speed and excellent error detection ability. Modern Nissan Sentra vehicle is equipped with many electronic control unit, 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-High line, CAN-Low line) allowing a high rate of information transmission with less wiring. Each control unit transmits/receives data but selectively reads required data only. CAN Communication Signal Chart. Refer to CAN Communication Signal Chart.
