Initialize power windows

On initialization of the power windows, two parameters are learned by the control unit:

• Upper end stop (normalization of the power windows).
• Power characteristic curve for opening and closing (learning the characteristic curve).

A power window is to be initialized:

• In the event of malfunctions, e.g. no one-touch function (automatic mode) possible for closing, no convenient closing possible, window reverses without anything being trapped
• Following the replacement of the power window drive
• Following repair work on the window seals or power-window mechanism
• Following the replacement or reprogramming of the control unit
