C1156 ST ANG SEN COM CIR
Description
The steering angle sensor is connected to the ABS actuator and electric unit (control unit) in addition to CAN lines. 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.
