DescriptionThe electric windows in the rear doors are operated by means of switches located in each of the rear doors.The operation of the rear windows takes place automatically, in accordance with the following logic which depends how the button is pressed.for opening the windows:the operation is manual (the glass goes up/down only when the button is pressed) when the button is held down for 60 to 300 milliseconds;the operation is instead automatic (the glass continues to go up/down to the end of travel, even if the button is released) when the button is held down for over 300 milliseconds;if the button is pressed again during movement of the glass, the glass is stopped instantly;if the button is pressed for less than 60 milliseconds, it is ignored (it is considered to have been knocked accidentally).for closing the windows:the operation is only manual
This control logic is controlled by the specific control unit under the dashboard on the passenger side.The control unit also carries out a series of safety checks.The stopping of the electric windows (switching off the electric supply to the motor) is determined when the glass reaches the end of travel at top or bottom, or if an obstacle blocks the glass. This is regulated by checking the motor current.If there are faults on the electrical circuits, the control unit switches the system off temporarily, for example if:the motor control signals are interrupted or if the current uptake is below the usual values.there is a fault in the control buttons (short circuit, or buttons jammed in the pressed position
For safety reasons a special lock switch in the dashboard allows the power supply to the rear switches to be excluded to prevent accidental operation, for example, by children.The rear electrically-operated windows will work only when the key is turned to MAR.The control switch symbols are lit when the key is turned to MAR.The control circuit for the rear electric windows is protected by a specific fuse, next to the junction unit.
Functional description The control unit M82 manages the operation of the electric rear windows. The direct supply to the control unit M82 - pins 7 and 2 of connector A - arrives from the direct line from the battery via maxifuse J/B2 of B5 and protected by fuse B17 . The supply controlled by the ignition (INT) reaches pin 2 of connector B, via the line protected by fuse F8 of the junction unit B1 . Pins 9 and 10 of connector A and pin 1 of connector B provide the reference earth. The rear electric windows switch H55 is supplied by the line controlled by the ignition (INT) rotected by fuse F8 of the junction unit B1 : with the button pressed (rear electric windows enablement) the switches in the doors H53 (left) and H54 (right) are also supplied. When the switches are operated, they send command signals (positive and negative) to the rear electric windows control unit M82; the above signals reach:pins 10 and 20 of connector B from the left switch H53 ;pins 9 and 19 of connector B from the right switch H54 ;
The control unit M82 controls the electric windows as described above:from pins 3 and 10 of connector A it sends commands to the rear left motor N65 .from pins 1 and 8 of connector A it sends commands to the rear right motor N66 .
When the positive and negative signals are reversed, the motor direction of rotation is also reversed.
