Nissan Sentra B18 (2020-2025) Service Manual: U1010 Control Unit(can)

Dtc Description

DTC Description

DESCRIPTION

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