Components DescriptionNKS004CH
CAN CommunicationNKS004CI
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 speed and excellent error detection ability. Many elec-
tric 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.
CAN COMMUNICATION UNIT

beam to measure distance from preceding vehicle.
ECM×××Transmits accelerator pedal position signal, ICC brake
switch signal, stop lamp switch signal and ICC steering
switch signal to ICC sensor integrated unit through CAN
communication.
