DESCRIPTION - ELECTRIC FRONT WINDOWS - Alfa Romeo 159 2.4 JTD 20V Fino a 12/05

The electric windows for the front doors are operated through the switches on the driver''s door (both windows) and the passenger side (passenger side only).The control units in the door control the operation of the driver''s and passenger side electric window motors which are operated both manually and automatically depending on the version.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-crush safety system (if fitted);- 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 windows are automatically opened or closed through the special prolonged (more than 2 seconds) command sent by the TEG remote control button.The circuit is controlled by the services relay and protected by two fuses located in the junction unit under the dashboard: there is a power supply both with the TEG inserted (ON) and not inserted (OFF); during the starting stage this relay is temporarily deactivated whilst with the TEG not inserted (OFF) the Body Computer keeps the relay activated for 3 minutes but deactivates it 30 seconds after one of the doors is opened.The driver''s door control unit acquires both the driver''s front door and passenger side front door commands; it manages the movement of the driver''s window directly and sends the relevant movement commands for the passenger side window via the CAN to the passenger door control unit which manages the passenger side window directly.

FUNCTIONAL DESCRIPTION - ELECTRIC FRONT WINDOWS - Alfa Romeo 159 2.4 JTD 20V Fino a 12/05

Service relay T13, located in the junction unit under the dashboard B2 , supplies the driver''s door control unit M66 - pin 8 of connector D and the passenger side control unit M67 - pin 8 of connector A , in accordance with the logic described above and controlled by the Body Computer M1, via two lines, protected by fuses F47 and F48. Pin 19 connector B and 7 of connector D of M66 and pin 7 of connector A of M67 are earthed. Control unit M66 is connected to the Body Computer M1 via the CAN line.Unit H44 contains the driver and passenger side window controls:: dedicated analogue signals are sent to pins 31 and 32 of connector A of M66 (pin 33 supplies a reference earth).. Similarly, the control at the front passenger door H50 sends a dedicated analogue signal to control unit M66 pins 1 and 4 of connector C.Cotnrol unit M66 controls the motor N60 (driver''s side) directly - pins 9 and 10 of connector D. The commands for motor N61 (passenger side) are sent from pins 2 and 3 of connector C via the control unit M67 from pins 9 and 10 of connector A.
