DescriptionThe vehicle is equipped with two dipped headlamps in the light clusters.The dipped beam headlamps are switched on through the steering column switch by turning the specific ring to the position after the side lights.A special relay - in the underdashboard control unit - controls the switching on of the dipped headamps via two lines protected by special fuses.The relay for switching on the dipped headlamps is managed by the Body Computer: the energizing of the relay is activated by the go ahead signals with the ignition key in the ON position (INT) and by the specific signal from the steering column switch unit.The Body Computer also manages the 'dipped headlampa maintenence' function: when the main beam headlamps are on, the Body Computer keeps the dipped headlamps on.If the dipped headlamps and the main beam headlamps are already on, then the fog lights cannot be switched on. Similarly, if the dipped headlamps and the fog lights are on and main beam headlamps are switched on, then the fog lights are switched off.The 'Follow me home' function is designed to keep the dipped headlamps and the side lights on after the engine has been switched off (key in OFF and/or PARK) for a time of 30 seconds or multiples thereof.Keeping the dipped headlamps on is signalled by the side lights warning light in the instrument panel remaining on.The funciton is switched on by operating the flasher lever within 2 minutes: each time the lever is operated the time the lights remain on increases by 30 seconds up to a maximum of 210 secs.Operating the flasher lever for longer than 2 seconds switches the function off; the function is also switched off if the ignition key is turned to the ON position.
Functional description The dipped headlamps activation signal is sent to pin 4 of connector D of the Body Computer M1 from the steering column switch unit H5 . The 'ignition ON' signal (INT) for the switch H1 reaches the underdashboard control unit B2 at pin 11 of connector H and from there moves on to the Body Computer M1 (pin 9 of connector F). The Body Computer M1 controls the supply of the dipped headlamps sending an earth signal to the underdashboard control unit B2 - from pin 8 of connector F of M1 - which energizes the relay T1: this supplies the dipped headlamps F10 (left) and F11 (right). Each circuit is protected by a control unit B2 fuse: F13 for the left headlamp and F12 for the right one.

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
