Fiat IDEA 1.4 16v – ELECTRIC FRONT WINDOWS – – High setup – WIRING DIAGRAM, LOCATION COMPONENTS, OPERATIONAL DESCRIPTION – WIRING DIAGRAM, LOCATION COMPONENTS, OPERATIONAL DESCRIPTION
DescriptionThe electric windows in the front doors are operated through the switches on the front driver's door (both windows) and the front passenger door (passenger side only).The door control unit control the operation of the driver and passenger side electric window motors.they are controlled in manual or automatic mode according to the specififcation.Automatic operation takes place as follows: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).Each control unit in the door also manages the anti-crush safety function: it acquires information on the possible presence of an obstacle during the movement of the window during closing (raising: a resistive sensor is inserted in a casing fitted to the upper seal which is compressed if there is an obstacle preventing the window from closing properly: in these circumstances the control unit immediately interrupts the travel of the window and reverses it to the bottom end of travel position.The correct operation of the anti-crush safety sensor is controlled by the check function. for the control unit: if there is a fault, this information is sent via the CAN to the instrument panel to light up the general failure warning light and to show the information on the display.In addition, if a fault is detected, the control unit inhibits the automatic closing operation, only allowing steps of 500ms every time the button is pressed. The windows are automatically opened or closed by a specific prolonged command (over 2 seconds) sent by the remote control button.The remote control receiver aerial is connected directly to the Body Computer which contains the electronics for the actual receiver.The circuit is controlled in accordance with the control logic for the door control units, whose supply is protected by two dedicated fuses and operated by the services relay for the junction unit under the dashboard: in this way the supply is ensured both the ignition ON and with the ignition OFF: during starting, this relay is temporarily deactivated, whilst with the ignition 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 the commands for the front driver's door and the front passenger door; . it manages the movement of the driver's window and transmits the passenger window movement commands via the CAN to the passenger door control unit which manages the passenger window directly.
Functional description The services relay T13, located in the unit under the dashboard B2, supplies with the above-mentioned logic and controlled by the Body Computer M1 - pin 14 of connector F - the controls units on the driver side door M66 and passenger side door M67 - pin 8 of connector E , H44 - pin 8 of connector D, via two lines, protected by the fuses F47 and F48. Control units M66 and M67 , are connected via a CAN line to one another and to Body Computer M1 . The unit H44 contains the commands for the driver's and passenger's windows: appropriate analogue signals are sent to pins 31 and 32 of connector A of M66 (pin 33 provides the reference earth). Control unit M66 controls motor N60 (driver side) directly and motor N61 (passenger side) via control unit M67 . Similarly, the control on front passenger door H50 sends an appropriate analogue signal to control unit M67 pin 32 (pin 33 supplies a reference earth)., which controls motor N61 . Pins 2 and 5 of Connector C of M66 and M67 receive signals from antipinch sensors K22 and K23 . The two control units are connected, via the CAN line, to the instrument panel E50 to manage the general failure warning light if faults are detected in the anti-crush sensors. The aerial-receivier P93 sends the Body Computer M1 the signal to open/close the doors and also windows and sunroof, by connecting to pins 21 and 31 of connector B 2399254SeeE3040CENTRAL LOCKING .
