DTC U1000, U1001 CAN COMMUNICATION LINE PFP:23710
Description UBS0091Z
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.
