- During driving more than 40km/h (24.9MPH) and stop 3 times, if master cylinder pressure is not changed
- During driving more than 40km/h (24.9MPH) and stop 3 times, if master cylinder pressure is higher than 10bar
|
| Case2 |
- If the gradient of the sensor signal per 10ms is higher than 15bar when any control is not activated
