Nissan Rogue (T33) 2021-Present Service Manual: U0155 Can Communication (combination Meter)

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 malfunction 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 unit is connected with 2 communication lines (CAN-H and CAN-L) allowing a high rate of information transmission with less wiring. Each control unit communicates data but selectively reads required data only.
