Code U0101 2017 Nissan Rogue 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.
If the Transmission Control Module (TCM) cannot communicate with the Engine Control Module (ECM), the TCM will conclude that there is a malfunction in the CAN system, illuminate the MIL, and set a Diagnostic Trouble Code (DTC).
