67 62 ... Notes On Initializing Power Windows







NOTE: Initialization is performed on the power window switch of the relevant door.

Initialization comprises:
- Normalization
- Learning characteristic curve

With normalization, the mechanical end stops of the power window regulator are recorded and stored.
The characteristic curve is learnt immediately after normalization.
When the characteristic curve is learnt, the mechanical closing forces of the power windows are recorded and stored for correct operation of the anti-trapping mechanism.
Initialization, i.e. normalization and learning of characteristic curve, is performed in a continuous operation.







NOTE:
An initialization must be performed:
- In the event of malfunctions, e.g. no one-touch function, no opening or no convenience function possible.
- After the power windows drive or door module has been replaced.
- After work is carried out on the power windows mechanism.







WARNING: There is no anti-trap mechanism during initialization.







Necessary preliminary tasks:
- Vehicle stationary
- Sufficient battery voltage available / connect charger if necessary
- Terminal "15" switched on
- All doors closed







Operating procedure for initialization (manual):

Deleting the initialization:
- Move side window into lower end position.
- Press and hold switch in "Open one-touch function" position (second switch position) for between 15 and 25 seconds.

NOTE: Deletion of initialization was successful if toll function and anti-trap mechanism have been rendered inoperative.

Performing initialization:
- Move side window to upper end position
- Pull and hold switch in "Close one-touch function" (2nd switch position) during the entire process.

NOTE: Re-initialization was successful if toll function and anti-trap mechanism function flawlessly.







Alternatively, initialization of the power window regulation can also be carried out via the Service function in ISTA.
Selection via:
- Body
- Locking and security functions
- Power window regulator
