312000962 - E3050 FRONT ELECTRIC WINDOWS - DESCRIPTION

DESCRIPTION

The front door windows are operated by switches located in the middle of the dashboard near the gear lever.On the basis of the signals received from the switches, the Body Computer manages the function according to the following logic:

  • if the button is pressed for between 50 and 300 milliseconds, operation is manual: the glass goes up/down only with the key pressed;
  • f the key is pressed for longer than 300 milliseconds, operation is automatic: even if the button is released, the window continues to close/open until it is in the end of travel position;
  • pressing the button again whilst the window is moving stops it in the position it is in;
  • if the button is pressed for less than 50 milliseconds, this is ignored (it is treated as an accidental knock).
The passenger side window only operates automatically during the opening stage.The electric window function operates only with the ignition on, with the following exception: after a key off (ignition OFF or key extracted), for a period of 3 minutes, it is possible to operate the windows; when this period has elapsed the system does not acquire new commands. If one of the doors is opened during the timed period, new commands are longer acquired, but any commands received before the opening of the door are brought to a conclusion. If one of the doors is already open at the key off, any commands received before the opening of the door are brought to a conclusion.The window raising/lowering circuit, operated by two relays integrated in the Body Computer, is supplied by the line protected by two dedicated fuses for the Body Computer. The circuit is excluded during starting.
On this version the windows electronic control does not include an anti-crush safety function. Therefore it is necessary to make sure before or during operation that there is no risk of the passengers being exposed to injury due directly to the movement of the windows or objects dragged along or projected by the actual windows.
