DTC Description: Description

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 independently). In CAN 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.
