Windows: Testing and Inspection

Initialization of the Power Window Regulators


Sporadic faults or switch-off can be rectified by deletion of an initialization and subsequent re-initialization.

Prerequisites:
- Vehicle stationary
- Sufficient battery voltage
- Terminal "R" or terminal "15" switched on
- All doors closed

Attention!
The anti-trapping mechanism is not active during initialization. Make sure that there are no persons or foreign materials in the area of the side window during initialization.





Deletion of the initialization by using the button:
- Full open the side window on the respective door.
- Keep the corresponding button fully pressed down for longer than 15 seconds and shorter than 20 seconds.

Deletion of the initialization was successful if the toll function is no longer possible.

Initialization by using the button:
- Fully close the side window by pulling the switch. Possibly the switch must be operated several times until the side window is fully closed.
- Then fully open the side window. Possibly the switch must be operated several times until the side window is fully open.
- Then close the side window by using the toll function. Do this by pulling the switch and keeping it pulled until the side window is completely closed.

The initialization was successful if the side window can be opened and closed without errors by using the toll function.
