ELECTRIC REAR WINDOWS - DESCRIPTION

DESCRIPTION

The electric windows in the rear doors are activated using the switches in the actual doors and the driver''s front door.

The motors are operated either manually or automatically, depending on the trim level.

Automatic operation takes place as follows:

- if the button is pressed is between 60 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 glass continues to move up/down until the end of travel position is reached or until the intervention of the anti-pinch safety system;

- 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 60 milliseconds, this is ignored (it is treated as an accidental knock).

The electronic circuit inside the motor manages the antipinch function: i.e. it acquires information about the possible presence of an obstacle during window closure (rising); the antipinch function is performed by a Hall effect sensor that senses overloads on the window motor; the action threshold is set when the force of the obstacle encountered along the window travel (e.g. a finger, a hand) exceeds 7/8 kg.

In addition, if a fault is detected, the control unit inhibits the automatic raising operation only allowing it in steps of 500ms each time the button is pressed.

the windows are automatically opened or closed through the special prolonged (more than 2 seconds) command sent by the remote control button.

The electric window function operates only with the ignition on, with the following exception: after key-off, the windows may be operated for a period of 3 minutes. When this period has elapsed, the system cannot receive new commands. If opening of one of the doors is detected during the timed period, no new commands are received but any commands received before door opening are completed. If one of the doors is already open at key off, any commands received before door opening are completed.

The rear control lock (protection) is operated by means of a LOCK key among the driver''s controls: the locking status is indicated by an LED beside the key lighting up and the rear control buttons are not lit up. The electric windows cannot be operated using any of the buttons when the lock function is activated.
