DTC U1000: Can Comm Circuit: Description

CAN (Controller Area Network) is a serial communication line for real time applications. It is an on board multiplex communication line with high data communication speed and excellent error detection ability. A modern vehicle is equipped with many ECMs, and each control unit shares information and links with other control units during operation (not independent). In CAN communication, two control units are connected with two 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.
It transmits the vehicle status to pre-crash seat belt control unit using the CAN communication system.
It consists of CAN system (unified meter and A/C amp., ICC sensor, BCM, steering angle sensor).
