C1156 NISSAN Description

  The steering angle sensor is connected to the Anti-Lock Brake System (ABS) Actuator and Electric Unit (Control Unit) in addition to Control Area Network (CAN) lines. CAN 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.
