Dipped Headlamps Bi-Led: Notes
DESCRIPTION
The dipped beam headlights are switched on using the steering column stalk by turning the ring nut forwards: the dipped beam headlights are activated, the daytime running lights switch off and the side lights, dipped beam headlights and number plate lights switch on.
The "Follow me home" function allows the dipped beam headlights and the side lights to remain on even after the engine has been switched off (key in STOP position or extracted) for a period of 30 seconds or multiples thereof. The side lights warning light in the instrument panel signals that the lights have remained on. It is turned on using the lever in the same way as for activating the flasher within 2 minutes of the ignition being turned to STOP: each time the lever is operated the length of time the lights remain on is increased by 30 seconds, up to a maximum of 210 seconds. Turning the key to the KEY-ON position or keeping the flasher lever pulled for more than 2 seconds eliminates the function. On bi-LED versions, the bulbs are replaced with high brightness and high efficiency LEDs.
FUNCTIONAL DESCRIPTION
: There is a single (ground) signal sent by the steering column stalk H005 to the Body Computer M001 that manages both the side lights and the dipped headlights: from pin 3 of H005 to pin 38 of connector F of M001; the signal sent is coded by means of resistive dividers so that multiple information can be sent by the steering column stalk to the Body Computer via a single connection.
- The reference ground reaches pin 10 of H005 from pin 34 of connector F of M001.
- The Body Computer M001 - connector A - receives a direct power supply from the battery through the line protected by maxi fuse F01 of the engine compartment control unit B001.
- The Body Computer M001 receives an ignition-operated power supply (INT) at pin 2 of connector E: this signal is used, amongst other things, to "wake up the network".
- The ground reference reaches pins 9, 10 of connector E of Body Computer M001.
- The Body Computer M001 controls the power supply for the dipped beam headlights in the headlamps F010 (left) and F011 (right) from pins 10, 27 of connector D of M001.
- The Body Computer M001 is connected through the CAN line to the instrument panel E050 to manage the "dipped beams on" warning light.
