Description - DIPPED HEADLAMPS - Fiat ULYSSE 2.2 16V JTD fino a 04/03

The vehicle is equipped with two dipped beams in the headlamps.The dipped beams are activated by turning a wheel on the stalk switch to the next position after the side light setting.A special relay in the engine compartment junction unit controls activation of the low beams via two lines protected by specific fuses.The low beam activation relay is managed by the body computer: relay excitation is activated by enablement signals with key in position M and a specific stalk switch command.Activation/deactivation information is sent via the CAN network: in this way, the main beam warning light is activated in the instrument panel.The body computer also manages the dipped beam maintenance function: when the main beams are turned on, the body computer keeps the dipped beams on.If the dipped beams and the main beams are already on and the fog lights are turned on, then the dipped beams are switched off.Similarly, if the dipped beams and the fog lights are on and the main beams are switched on, the dipped beams are switched off.In other words, when the main beams and the fog lights are on, the dipped beams are always off.The dipped beams can also be activated automatically, using the AUTO button on the steering column switch unit: this function is achieved by means of an infrared dusk sensor located in the windscreen.Activation and deactivation is accompanied by an auditory warning signal.769When the device is switched on, the lights come on automatically even if the windscreen wiper is operated.The "Follow me home" function allows the dipped headlamps and the side lights to remain on even after the engine has been switched off (key in position S) for a period of 45 seconds.The side lights warning light in the instrument panel signals that the lights have remained on. The lights are activated by operating the light flasher stalk within 2 minutes of switching the engine off.

The command to switch on the dipped headlamps is supplied by the steering wheel node control unit M093 to the body computer node M001. The signal travels via the CAN which connects the two control units.The steering wheel node control unit M093 receives a supply (pin 5 connector A) through the line protected by fuse F11, located in the body computer node M001; it receives a supply via the CAN (pin 6 connector A) from the line protected by fuse F16, located in the body computer node M001.The body computer node M001, in turn, informs the engine compartment junction unit B001, via the CAN, of the request to switch on the dipped headlamps.The relay inside the engine compartment junction unit B001 is energized, supplying the front light clusters F010 and F011 through the lines protected by fuses F09 and F10 both housed in the junction unit B001.The warning light is switched on by the milometer warning lights node M140 which communicates with the instrument panel E050 and the body computer node M001 via the CAN.The instrument panel E050 and the milometer warning lights node M140 receive a supply via the CAN (pin 13 of E50 and pin 4 of M140) through the line protected by fuse F24 of the body computer M001.The instrument panel E050 and the milometer warning lights node M140 receive a supply via the CAN (pin 13 of E50 and pin 4 of M140) through the line protected by fuse F24 of the body computer M001.
