Automatic Raising/Lowering of Power Windows

Function requirements
- No overvoltage/undervoltage
- Circuit 15R or circuit 15 ON
- Power windows in normalized state (for automatic raising)
- Function not disabled (version coding)
- Power window motor rotation direction correct
- No defective Hall sensors

Function
The automatic raising/lowering function is performed by briefly pulling back or pushing forward a power window switch in the "close" or "open" direction beyond the first click-stop position. The respective door control module (N69/1. N69/2, N69/3 or N69/4) reads the switch state and actuates the corresponding power window motor (M10/3, M10/4, M10/5 or M10/6) until the window is completely closed or open as detected by position recognition.


NOTE: Model 203.7 has no rear door control modules or power window motors.


Automatic raising
The "automatic raising" function effects automatic window raising with excess force limitation (obstruction sensors) and can only be performed on normalized windows. As long as no other button signals are detected, the window will be fully raised to the upper end stop position.

If the system detects that the rotation direction of the power window motor is incorrect or that a Hall sensor is defective for 12 rotations of the armature, automatic raising is immediately aborted.

Upon detecting an "incorrect rotation direction" or "defective Hall sensor" fault, or a denormalized window, the system will respond to any continued request for "automatic raising" by actuating the "manual raising" function.

If the system recognizes the "manual raising" button function after having recognized the "automatic raising" button function and without first having detected the neutral position, the "automatic raising" function remains active.

Function abort
The "automatic raising" function is aborted if:
- Function requirements are not satisfied
- A lock-up is recognized
- Another switch position after neutral position is detected
- A response is detected from the excess force limiter (obstruction sensor)
- Active > 25s
- Zero point tolerance exceeded

Automatic lowering
The "automatic lowering button function effects automatic window lowering and can be performed without normalization. As long as no other button signals are detected, the window will be fully lowered to the lower end stop position.

Function abort
The "automatic lowering" function is aborted if:
- Function requirements are not satisfied
- Another switch position after neutral position is detected
- A lock-up is recognized
- Active > 25s
- The maximum travel distance for normalized windows is exceeded
