Code U1001 2010 Nissan Sentra Description

The Controller Area Network (CAN) is a serial communication line for real-time applications. It is an on-vehicle multiplex communication line with high data communication speed and excellent error detection ability. Many electronic control units are equipped onto a 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 the required data only.
The Diagnostic Trouble Code (DTC) sets when the Engine Control Module (ECM) is not transmitting or receiving CAN communication signals of OBD (emission-related diagnosis) for 2 seconds or more.
