[08/2015 - ]
1. BRIEF DESCRIPTION
(a) The Controller Area Network (CAN) is a serial data communication system for real time application. It is a
vehicle multiplex communication system which has a high communication speed and the ability to detect
(b) Using the CANH and CANL bus lines as a pair, CAN communication is performed using a voltage
differential. (A base voltage is applied to the pair of lines and a voltage differential is created when
(c) Many ECUs or sensors installed on the vehicle operate by sharing information and communicating with
(d) The CAN has two resistors of 120 Ω which are necessary to enable communication.
2. DEFINITION OF TERMS
(a) Main bus
(1) The main bus is a wire harness between the two terminating resistors on the bus. This is the main bus
in the CAN communication system.
(1) A branch is a wire harness which diverges from the main bus to an ECU or sensor.
(c) Terminating resistors
