DescriptionThe boot open motor is operated by:the button on the dashboard;the remote control.The control unit built into the commands unit on the door controls the operation of the boot lock release: it receives the request to open the boot from the Body Computer or from the control signal from the relevant button on the dashboard., and consequently issues a command to an external relay, located under the dashboard behind the Body Computer.The boot opening logic is as follows:when the ignition is on, the control button causes the boot to open if the vehicle speed is 0 km/h;with the ignition off, or when one of the doors is opened, the control button operates for a timed period of 3 minutes.Whenever the control button is pressed, a confirmation beep is issued - via a signal transmitted on the CAN - by the instrument panel buzzer.If the Body Computer detects that one of the doors or the boot has been left open and the vehicle speed exceeds around 3 Km/h, a buzzer is sounded. The remote control receiver aerial is connected directly to the Body Computer which contains the electronics of the receiver proper: the remote control is located in the key, on which a specific button controls the boot release (a further two buttons control the door lock and release 3023301SeeE3040CENTRAL LOCKING ). The Body Computer receives the boot open request from the remote control and, with the ignition off, sends the command to the unit on the door.

Functional description The Body Computer M1 receives as input the signals coming from the aerial-receiver P93 , which is connected to pins 21 and 31 of connector A. Via the CAN line, the Body Computer M1 is connected to the controls unit on the door H44 . The controls unit on the door H44 is supplied - pin 24 of connector B - from the line protected by the fuse F39 of the unit under the dashboard B2 . The unit H44 receives as input the signal from the release button, located in the controls unit H12 , at pin 3 of connector B. According to the control logic described above, the unit H44 sends a command from pin 6 of connector A, which energizes the boot opening relay J56 which, supplied by the line protected by shunt fuse B60 , controls the operation of the boot lock geared motor N57.

Follow these precautions:769768768

5530B18

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
