FAIL-SAFE

Engine Control System

Engine operating condition in fail-safe mode
Fail safe mode		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.
Traveling control mode	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.
Device fix mode		This mode fixes the electric IVT motor and the EVT control solenoid valve in the reference position. The intake manifold runner control valve motor is turned OFF (intake manifold runner control valve opens).

Idle Start/Stop System

When a DTC is detected, the start/stop indicator lamp blinks slowly and the idle start/stop system operation is prohibited.

When ECM detects error while operating the idle start/stop system, ECM restarts the engine.
