DescriptionThe front courtesy light includes two bulbs with two control switches.With the left switch (A) it is possible to select the following two operating modes:centre position: both lights come on for a timed periodleft-hand position: both lights are off all the time;right-hand position: both lights are on all the time.The right-hand switch turns on only one of the lights:left-hand position: left-hand light always on;right-hand position: right-hand light always on;central position: both lights always off.The rear courtesy light only has one bulb with different operating modes according to the position of the actual lens cover which operates an internal switch:neutral position: light comes on for a timed period;positioned to one side: lights always off;positioned to the other side: light always on.The lighting for the two courtesy lights is timed on the basis of a logic managed by the Body Computer.when one of the front doors is opened, the two courtesy lights are timed to stay on for 3 minutes;when one of the rear doors is opened, the single rear courtesy light is turned on for a timed period of 3 minutes;f, whilst opening one door, another is opened, the counting of the three minutes starts again from zero;if a door remains open for longer than three minutes, the courtesy lights go out and remain off until one of the doors is next opened;If, during this period of 3 minutes, all the doors are closed again, a second period of 7 seconds is activated and is interrupted if the ignition key is turned on.when the doors are opened using the remote control, the courtesy lights come on for 10 seconds; the timing is interrupted if the ignition key is turned ON;when the remote control is used to lock the doors, the courtesy lights go off.The switching off and on should be gradual (dimmer) with a cycle lasting 2 seconds.When the ignition key is turned OFF, the Body Computer checks that the key has actually been removed (no transponder): in these circumstances it switches the front and rear courtesy lights on as described previously.The courtesy lights are also on (without the dimmer) if the inertia switch is operated (the information is sent via the instrument panel CAN).The function is activated with the ignition key in the ON position and remains on for a maximum of 15 minutes.The Body Computer continuously acquires the 'battery voltage' signal and compares it with a limit: if the battery voltage level measured is below this limit, it intervenes through the CAN sending a signal to disable a series of loads: these include the two front and rear courtesy lights; the function is activated with the ignition key in the OFF position.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.
Functional description The Body Computer M1 receives the 'door open' input signals at pin 8 (driver's door), pin 25 (front passenger's door), pin 16 (rear left door) and 26 (rear right door) of connector E. On the basis of the timing and control logic described previously, the Body Computer M1 supplies the two courtesy lights:from pin 23 of connector E it supplies the front courtesy light G10 ; from pin 21 of the same connector it supplies the earth signal for the timer;from pin 33 of connector E it supplies the rear courtesy light G20 ; from pin 37 of the same connector it supplies the earth signal for the timer; The Body Computer M1 is connected, via the CAN line, to the instrument panel E50 , from which it receives the 'inertia switch operated' signal which lights up the courtesy lights and sends a signal which, if necessary, can light up the 'doors open' warning light. 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
