DescriptionThe vehicle is equipped with two dipped headlamps in the lightclusters.The dipped beam headlamps are switched onthrough the steering column switch by turning the specific ringto the position after the side lights.A special relay - in the underdashboardcontrol unit - controls the switching on of the dipped headampsvia two lines protected by special fuses.The relay for switching on the dipped headlampsis managed by the Body Computer: the energizing of the relay isactivated by the go ahead signals with the ignition key in the ON position(INT) and by the specific signal from the steering column switchunit.The Body Computer also manages the 'dippedheadlampa maintenence' function: when the main beam headlamps areon, the Body Computer keeps the dipped headlamps on.If the dipped headlamps and the main beamheadlamps are already on and the fog lights are switched on, thenthe dipped headlamps are switched off. Similarly, if the dipped headlamps and thefog lights are on and main beam headlamps are switched on, thenthe dipped headlamps are switched off.In other words, with the main beam headlampsand the fog lights on, the dipped headlamps are always switchedoff.The dipped headlamps are activated automatically,via the dusk sensor, if the AUTO function is set on the steeringcolumn switch unit.The 'Follow me home' function is designedto keep the dipped headlamps and the side lights on after the enginehas been switched off (key in OFF position) for a time of 30 secondsor multiples thereof.Keeping the dipped headlamps on is signalledby the side lights warning light in the instrument panel remainingon.The funciton is switched on by operatingthe flasher lever within 2 minutes: each time the lever is operatedthe time the lights remain on increases by 30 seconds up to a maximum of210 secs.Operating the flasher lever for longer than2 seconds switches the function off; the function is also switchedoff if the ignition key is turned to the ON position.
Functional description The dipped headlamps activation signal is sent to pin 2 of connectorI of the Body Computer M1 from the steering column switch unitH5. The 'ignition ON' signal (INT) for the switchH1 reaches the underdashboard control unit B2 at pin 11 ofconnector H and from there moves on to the Body Computer M1 (pin9 of connector F). The dipped headlamps are also activatedif the dusk sensor K85 is fitted (signal at pin 7 of connectorD of M1); The dusk sensor K85 is supplied from the INT lineprotected by fuse F49 of control unit B2. The Body Computer M1 controls thesupply of the dipped headlamps sending an earth signal to the underdashboardcontrol unit B2 - from pin 8 of connector F of M1 - which energizesthe relay T1: this supplies the dipped headlamps F10 (left)and F11 (right). Each circuit is protected by a junctionunit B2 fuse F13 for the left headlamp and F12 for the rightone.

Prepare the vehiclecomplete with spare wheel, tools, fluids, fuel reserve and driveron board.Check that the tyre inflation pressureis correct.Place the headlamp alignment switch inposition '0'.Position the vehicle on a flat surface,perpendicular to a screen or an opaque surface, 10 metres away,which contains the following lines.1. V - V: vertical line corresponding to the trace of the planeof symmetry of the vehicle.2. C - C: traces of the vertical planes passing through the referencecentres of the light clusters.3. HC - HC: horizontal line corresponding to the height from theground of the reference centres for the light clusters.4. AC - AC: horizontal line 12 cm below the HC - HC line.5.
