2427904 - E2011 DIPPED HEADLAMPS - Description

Description

The 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 and the fog lights are switched on, then the dipped headlamps are switched off. Similarly, if the dipped headlamps and the fog lights are on and main beam headlamps are switched on, then the dipped headlamps are switched off.In other words, with the main beam headlamps and the fog lights on, the dipped headlamps are always switched off.The dipped headlamps are activated automatically, via the dusk sensor, if the AUTO function is set on the steering column switch unit.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 position) 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.
