U1000 CAN COMM CIRCUIT
DescriptionINFOID:0000000006216248
CAN (Controller Area Network) is a serial communication line for real-time application. It is an on-vehicle mul-
tiplex communication line with high data communication s peed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independently). In CA N communication, control units are connected with 2
communication lines (CAN-H, CAN-L) allowing a high rate of information transmission with less wiring. Each
control unit transmits/receives data but selectively reads required data only.

CAN COMMUNICATION SYSTEM : CAN Communica-
tion Signal Chart".
