PURPOSE: A CAN(Controller Communication Networks) communication system is provided to prevent the confusion of each system by fixing the positions of resistances in the systems. CONSTITUTION: A CAN communication system comprises an EMS(Engine Management System), CAN communication buses(131,132) and many sub controllers(140). The sub controllers communicate data with the EMS through the CAN communication buses. A first resistance(111) to be connected with the one side of the CAN communication buses is installed in the EMS. A second resistance(121) is connected with the other side of the CAN communication buses. Thereby, the confusion on a design is prevented and a regular potential difference between each terminals of the CAN communication buses is maintained.
