Electric front windows

Front windows with manual and automatic up, down controls and anticrush functionThe system consists of driver and passenger side window controls on the doors; anticrush sheaths on the right front window and left front window plus two R and L window motors.The control unit (NPG) controls operation of the driver and passenger side window motors.The driver and passenger side window motors are controlled manually or automatically in accordance with a specific strategy.Movement takes place with the ignition key ON and also with the key OFF.(a) key on (k-on)Movement takes place as described in the table

	Driver's Side Front Window	Passenger Side Front Window
UP control	MANUAL movementAUTOMATIC movement	MANUAL movement
DOWN control	MANUAL movementAUTOMATIC movement	MANUAL movementAUTOMATIC movement

(b) key off (k-off)Movement is only manual and timed by the NBC, which controls service relay 2 supplying the NPG and NVB nodes. Note that service relay 2 is located on the facia control unit (CPL) - T13 - is active with the ignition key ON and deactivated temporarily during start-up.If an INT signal is not received from the ignition, the (NBC) maintains service relay 2 supplying the windows and sun roof active and changes the timing for 3 minutes ± 10% but deactivates it immediately when one of the two front doors is opened.If a window control (front or rear) is pressed within three minutes of controlling service relay 2, the NBC resets the timer for a further 3 minutes.Control buttonsRight window up/down (front and rear window control), unstable rocking typeLeft window up/down (front and rear window control), unstable rocking type Each time the window function control buttons are pressed, the buzzer in the NQS goes off as confirmation: changes of status from depressed/released (rocker buttons) must be supplied via the CAN network. The NQS is responsible for managing duration and tone and then implementing indications in the presence of simultaneous controls.Manual systemMode is manual when the user starts and stops the system by hand by means of the control buttons. The motor stops when the buttons are released.Automatic system

Mode is automatic when movement is started by pressing the control button for a period in excess of a preset value. In automatic mode, window arrest (electric power to window motor cut off) is brought about by:

the window reaching the upper or lower end of its travel
the safety system (anticrush)
once a new raise or lower control has been pressed.

This is regulated by controlling motor current, which must be self-adaptive, and by managing the anticrush sensor.Disablement

Glass movement is disabled by:

Vbatt = 16 V (re-enabled for Vbatt = 15.5 V)
Vbatt = 10 V (re-enabled for Vbatt = 10.5 V)

The battery voltage level is supplied to the network by means of a specific message.Activation with remote control1) SUPERCLOSURE (only if the anticrush seal is present)Door closure takes place when the lock button is pressed. When the button is depressed for more than 4 seconds, the windows begin to raise, the sunroof closes and the alarm (if present) is activated When the button is released, movement is suspended. The button must be pressed again for 4 seconds to resume movement.2) SUPEROPENINGWhen the release button is pressed, the doors are opened and the courtesy light comes on simultaneously When the button is depressed for more than 4 seconds, the windows descent, the sun roof opens and the alarm (if present) is deactivated. When the button is released, movement is suspended. The button must be pressed again for 4 seconds to resume movement.Driver's side windowThe control unit should not operate when the control buttons are pressed for less than 60 ms.Manual movement is activated if the control key is pressed for time: Ta = Activation time > 60 ms and < 300 ms (short control)Automatic operation is activated if the control button is pressed for longer than: Ta > 300 ms (long control)The window power supply is enabled with the key on and the battery supplying the control unit.
