U1b2e-86 Can Comm Circuit

DTC Description

CAN COMMUNICATION

CAN (Controller Area Network) is a serial communication line for real time applications. It is an on-Nissan Pathfinder vehicle multiplex communication line with high data communication speed and excellent error detection ability. Modern Nissan Pathfinder vehicle is equipped with many electronic control units, and each control unit shares information and links with other control units during operation (not independent). In CAN communication, control units are connected with 2 communication lines (CAN-H, CAN-L) allowing a high rate of information transmission with less wiring. Each control unit transmits/receives data but selectively reads the required data only.
