Nissan Juke Service and Repair Manual : U1000 can comm circuit

Description

CAN (Controller Area Network) is a serial communication line for real time applications. It is an on-board multiplex communication line with high data communication speed and excellent error detection ability. A modern vehicle is equipped with many ECMs, and each control unit shares information and links with other control units during operation (not independent). In CAN communication, 2 control units are connected with 2 communication lines (CAN-L line and CAN-H line) allowing a high rate of information transmission with less wiring.

Each control unit transmits/receives data but selectively reads required data only.

Refer to LAN-31, "CAN COMMUNICATION SYSTEM : CAN Communication Signal Chart" for details of the communication signal.
