Nissan Rogue (T33) 2021-Present Service Manual: U0146 Can Communication
DTC Description
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-Nissan Ariya vehicle multiplex communication line with high data communication speed and excellent error detection ability. Many electronic control units are equipped onto a Nissan Ariya vehicle, 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 line, CAN L line) allowing a high rate of information transmission with less wiring. Each control unit transmits/receives data but selectively reads required data only.
