DescriptionThe 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 3023301SeeE3040CENTRAL LOCKING .
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 rear electric windows unit M82 - pins 7 and 8 of connector B, via two lines, protected by the fuses F33 and F34. Via the CAN line, the Body Computer M1 is connected to the electric rear windows control unit M82 - pins 8 and 9 of connector B - on the controls unit on door H44 . Via the CAN line, the unit H44 - which includes the controls for the electric windows and the 'REAR' and 'LOCK' buttons - sends the corresponding commands to the rear electric windows unit M82 . The rear electric windows control unit M82 is supplied - pin 5 of connector A - from the line protected by the fuse F39 of the underdashboard unit B2 . Pin 1 of connector A of M82 receives the command from the electric window switch on the rear left door H53 ; pin 10 sends the supply to light up the button of H53 . Pin 2 of connector A of M82 receives the command from the electric window switch on the rear right door H54 ; pin 11 sends the supply for lighting up the button of H54 . Pins 6-7 and 3-4 of connector A of M82 receive the signals of the anti-collision sensors K19 and K24 . The lines which supply - pins 3-4 and 1-2 of connector B - the motors N65 (left) and N66 (right) depart from the control unit M82. Pins 5 and 6 of connector B of M82 are earthed. The aerial-receiver P93 sends to the Body Computer M1 the open/close signal for the doors and windows, connecting to pins 21 and 31 of connector A.

Follow these precautions.769On batteries with an opticam hydrometer,electrolyte level and battery charge status can be monitored qualitativelyby examining the indicator colour: a light, bright colour indicates low electrolytelevel: top up with distilled water;a dark colour without a green area in thecentre indicates that the electrolyte level is correct but chargeis low: recharge the battery; a dark colour with a green area in themiddle indicates that both electrolyte level and charge status arecorrect: no action is necessary. For further details, see DESCRIPTION ANDOPERATION - 5580.768Proceed as follows.Check the battery voltage without loadusing the test device recommended by the Service outlets (e.g. 'MICRO360'). Depending on the voltage values measured,which define the state of charge of the battery, proceed as follows:If the voltage without load is less than12.10 V, replace the battery (see op.). 5530B10).If the voltage without load is over 12.10V but less than 12.50 V, recharge the battery (see op. 5530B14).If the voltage without load is over 12.50V, the battery is efficient.If necessary, top up the electrolyte asfollows.Carefully remove the cap strip.Top up with distilled and deionized water,taking care not to allow electrolyte to splash out.768
