3023326 - E3051 ELECTRIC REAR WINDOWS - Description (5 porte)
Description
The electric rear control unit, together
with the control unit incorporated in the controls unit on the front
door, controls the operation of the driver's and passenger's electric windows
motors.The driver's and passenger's motors
are controlled in both manual and automatic mode, in accordance
with the following logic:
- if the button is pressed for between 60 and 300 milliseconds,
the operation is manual: the window closes/opens only when the button
is pressed;
- if the button is pressed for over 300 milliseconds, the
operation is instead automatic: even if the relevant button is released,
the window continues to close/open as far as the end of travel or
until the anti-collision safety system intervenes, if applicable;
- a subsequent press on the button during movement of the
window locks it in its current position;
- if the button is pressed for less than 60 milliseconds,
it is ignored (it is considered to have been knocked accidentally).
Closing is only manual.In the case of inconsistent commands issued
simultaneously from two buttons, there is no movement.At each press of the electric windows control
buttons, a confirmation beep is emitted by the buzzer in the instrument
panel.The control unit incorporated in the controls
unit on the driver's door also manages the electric rear windows
control: if the specific 'REAR' button is pressed, the two buttons located
on the driver's door control the rear windows; if the button is
pressed again - or 20 seconds after the last activation - control
is passed on to the buttons located on the rear doors, while the
buttons on the driver's door go back to controlling the front windows;
the previous state of activation is indicated by an LED on the rear
of the button coming on.The control unit on the driver's door also
manages the locking of the rear controls (protection), done by pressing
the specific 'LOCK' button: the lock status is indicated by an LED on
the rear of the button coming on and the absence of illumination
of the rear control buttons. With lock activated, no button controls
the electric rear windows.The control unit on the driver's door also
acquires information concerning the possible presence of an obstacle
during movement of the rear windows (closing) by means of the anti-collision
seals: if this happens the window's travel is immediately stopped
and reversed.The circuit is controlled by the services
relay and protected by two specific fuses, all located in the unit
under the dashboard.Movement takes place whether the ignition
in ON or OFF.With the ignition on, it takes place as
described above; in addition during starting, this relay is temporarily
deactivated.With the ignition off, the Body Computer
keeps the relay activated - which also supplies the door mirrors
and electric windows - for 3 minutes, but deactivates it immediately when
one of the two front doors is opened.Movement is also disabled when the battery
voltage is below 10 V.
The windows are automatically closed by
the specific prolonged command (over 4 seconds) sent by the remote
control button, if the ignition is off; for more details
