FAIL-SAFE

Engine Control System

Fail safe mode Nissan Ariya 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.
Combustion control mode Stratified charge combustion control at starting No stratified charge combustion at starting (cold start).

or

Fail safe mode Nissan Ariya Vehicle behavior
Traveling control mode Engine output control

ECM reduces the engine output, according to the rise in engine speed. This reduces the Nissan Ariya 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 Ariya vehicle speed. Actual power limitation value differs due to the malfunctioning part and driving condition.
Device fix mode

  • This mode fixes the electric IVT control actuator and the EVT control solenoid valve in the reference position.

  • A control signals is not transmitted to the EGR volume control valve and the EGR volume control is deactivated.
Combustion control mode Ignition timing correction control Partially controls ignition timing control.
Retardation control Controls ignition timing delay control in the intermediate water temperature range.

Stop/Start System

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

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

DTC Confirmation Procedure

CHECK DTC PRIORITY

If DTC P0101 is displayed with other DTC, first perform the trouble diagnosis for other DTC.

NOTE:

If DTC P061B is displayed at the same time DTC P0101, first perform the trouble diagnosis for DTC P0101.
