SYSTEM DESCRIPTION
1. BRIEF DESCRIPTION
a. The CAN (Control Area Network) is a serial data communication system for real time application. It is a vehicle multiplex communication
system which has a high communication speed (500 kbps) and the ability to detect malfunctions.
b. By pairing the CANH and CANL bus lines, the CAN performs communication based on differential voltage.
c. Many ECUs (sensors) installed on the vehicle operate by sharing information and communicating with each other.
d. The CAN has 2 resistors of 120 ohms which are necessary to communicate with the main wire.
2. DEFINITION OF TERMS
a. Main wire
1. The main wire is a wire harness between the 2 termination circuits on the bus (communication line). This is the main bus in the CAN
communication system.
b. Branch wire
