Dtc Description

DTC 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 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.

Nissan Sentra Vehicle behavior

Traveling control mode

Accelerator angle variation control

ECM controls the accelerator pedal depression speed to make it slower than actual speed. This causes a drop in accelerating performance and encourages the driver to repair malfunction.

Note:

ECM does not control the accelerator pedal releasing speed.

Engine output control 1

ECM reduces the engine output, according to the rise in engine speed. This reduces the Nissan Sentra vehicle speed to encourage the driver to repair malfunction.

Driving at 70 km/h (44 MPH) or more is possible.

Note:

This value is a reference value converted from engine power to Nissan Sentra vehicle speed. Actual power limitation value differs due to the malfunctioning part and driving condition.
