LAN CAN COMMUNICATION SYSTEM LAN-13 < FUNCTION DIAGNOSIS > [CAN FUNDAMENTAL] C D E F G H I J K L B A O P N FUNCTION DIAGNOSIS CAN COMMUNICATION SYSTEM System Description INFOID:0000000001162753 • CAN communication is a multiplex communication system. This enables the system to transmit and receive large quantities of data at high speed by connecting control units with two communication lines (CAN-H and • Control units on the CAN network transmit signals using the CAN communication control circuit. They receive only necessary signals from other control units to operate various functions. • CAN communication lines adopt twisted-pair line style (two lines twisted) for noise immunity.
