Short Drop: Function
The short drop (SD) functionality is linked to the door ajar signal. In case of door opened, the door ajar signal (low level) will be received by the ECU. As a result the upper stop position will be changed from upper mechanical block position to the short drop position (EEPROM parameter). Short drop commandos will be executed independent of multi function line state.
Window lifter behavior due to door ajar signal:
| Window | Event | Action |
|---|---|---|
| Closed | Door opened → Short drop active | Glass moves down to SD position |
| Over SD position | Door opened → Short drop active | Glass moves down to SD position |
| Below SD position | Door opened → Short drop active | Glass will not move, but upper stop position will be changed to SD position |
| SD position | Door opened → Short drop active | Glass will not move, but upper stop position will be changed to SD position |
| SD position | Door closed → Short drop inactive | Glass will move to upper block position, upper stop position is equal to mechanical stop SD position |
| Below SD position | Door closed → Short drop inactive | Glass will not move, but upper stop position will change to mechanical stop position |
