FAIL-SAFE
Engine Control System
| 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.
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 |
|
|
| 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.
