DescriptionThe are two lights in the front doors which light up the ground.When the front doors are opened, the Body Computer notifies the door control unit of the status of the doors. The latter switches on the lights in the doors.The function is activated both with the ignition switched OFF or ON.The lights come on for a maximum of 3 minutes when one of the front doors is opened; when this time has elapsed the lights can only be turned on again if one of the doors is opened again.The lights go out immediately if both of the doors are closed.The Body Computer continuously acquires the 'battery voltage' signal and compares it with a limit: if the battery voltage level goes below this limit, it intervenes via the CAN using a signal to disable a series of loads: these include the door courtesy lights; the function is activated with the ignition key in the OFF position.

Functional description The Body Computer M1 receives the 'door open' input signals at pin 8 (left door) and pin 25 (right door) of connector E. The Body Computer M1 is connected, via the CAN line, to the controls in the front door H44 according to the control logic described previously, which supplies the two door courtesy lights G51 and G52 . The unit H44 is supplied by the line protected by fuse F39 of the underdashboard control unit B2 . The 'low battery voltage' signal which switches off the courtesy lights if they are on, always arrives via the CAN 3023163SeeE1050CAN CONNECTION LINES .

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
