Description - ELECTRIC FRONT WINDOWS - Alfa Romeo GT 2.0 JTS

One specific electric windows control unit for each door ensures the operation of the driver''s and passenger electric window 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).In the case of inconsistent commands issued simultaneously from the driver''s and passenger''s side, 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.767The up/down commands do not reach the electric windows control unit directly, but via the control unit on the door which retransmits them.The electric windows control unit also downloads information about the presence of an obstacle during the movement of the window when closing (up) by means of two Hall effect sensors in each motor. If an obstacle is detected, the control unit immediately interrupts the travel of the window and reverses it: this takes place in both manual and automatic operation.The two Hall effect sensors also allow the control unit to memorize the position of the glass at all times.Given the particular shape of the door (no upper frame) it is necessary to make sure that the door housing seal is correct by ''raising'' the glass into the seal with the door closed.For this reason the control unit also manages the short drop function:when the door is opened, if the glass is in the upper end of travel position, it is lowered by about 4 mm;when the door is closed, the glass, on the other hand is completely closed;if there is a command to close the window with the door open, the window stops about 4 mm before the top end of travel position; and the travel is only completed with the door closed.The circuit for the control unit for the controls on the door is controlled by the services relay and protected by two fuses, all located in the unit under the dashboard.The electric windows control unit circuit is controlled by the services relay and protected by two fuses in the additional fuse box.The relay is constantly supplied with the ignition ON, even during starting.With the ignition OFF, the Body Computer keeps the relay activated for 3 minutes, but deactivates it 30 seconds after one of the two doors is openedThe windows are automatically opened or closed by the specific prolonged command (over 4 seconds) sent by the remote control button; if the ignition is OFF the Body Compuer keeps the relay activated for 30 seconds.

The services relay T13, located in the unit under the dashboardB2, supplies with the above-mentioned logic and controlled by the Body ComputerM1- pin 14 of connector F - the controls unit on the doorH44- pins 14 and 25 of connector B, via two lines, protected by the fuses F47 and F48.Via the CAN line, the Body ComputerM1is connected to the controls unit on the doorH44.The control unit on the doorH44 is supplied directly at pin 24 of connector B by the line protected by fuse F39 of the junction unit under the dashboard B2.The services relay T12 supplies the driver''s electric window control unitM116 and the passenger electric window control unit M117 pin 20 of connector B through an ignition-operated line (INT/A) protected by fuse F62 of B2. An ignition-operated supply (INT) reaches pin 20 of connector B ofM116 and M117.Pins 9 and 10 of connector A and pin 1 of connector B ofM116 and M117 are earthed.The driver''s electric window control unitM116 and the passenger electric window control unit M117 are supplied directly at pins 2 and 7 of connector A by the line protected by fuses F64 and F65 of the additional fuse box B98.UnitH44 contains the commands for the driver''s and passenger windows, whilst pin 1 of connector A of H44 receives the command from the electric window switch on the passenger door H50 (this is a simple switch and does not include any electronics).The signals are sent from pin1-2 and 13-12 of connector B to the driver''s electric window control unitM116 and to the passenger electric window control unit M117, to pins 7 and 12 of connector BThese control the motorsN60 (driver''s side) and N61 (passenger side) from pins 3 and 8 of connector A.The two Hall effect sensors contained in the motorsN60 and N61 are supplied by the control unit M116 of M117 from pins 12 of connector A, whilst pin 11 provides the reference earth;the control signals are sent from pins 3 of connector B ofM116 or M117 (from sensor ''B) and from pins 4 of connector B of M116 or M117 (from sensor ''A'').The doors open signal, used for the short drop function, reaches pin 11 of connector B of M116 or M117 from the locks N50 and N51 (these are the same signals that light up the timed lights ).
