C1156 ST ANG SEN COM CIR BRC-65 < DTC/CIRCUIT DIAGNOSIS > [VDC/TCS/ABS] C D E G H I J K L M A B BRC N O P C1156 ST ANG SEN COM CIR Description INFOID:0000000009883675 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. DTC Logic INFOID:0000000009883676 DTC DETECTION LOGIC DTC CONFIRMATION PROCEDURE 1.
