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.
ECM does not control the accelerator pedal releasing speed. |
| Device fix mode |
|
|
| Combustion control mode | Stratified charge combustion control at starting | No stratified charge combustion at starting (cold start). |
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.
