DESCRIPTION - INSTRUMENT LIGHTING - Fiat 500 1.2 8v

The car is equipped with numerous light sources for optimal lighting of interior instruments and controls.Some of these controls are lit with the ignition key to MAR (INT), others with the side lights on, others can be dimmed in accordance with a rheostat-controlled adjustment strategy managed by the Body Computer and instrument panel.With the side lights on, the Body Computer manages the lighting of:cigar lighter;radio display (aftermarket versions only);backlit heater / manual air conditioner controls.The Body Computer manages the exterior lights activation information and transmits it over the B-CAN.The brightness of the instrument panel and other vehicle controls and displays (radio and climate control, where fitted) can be set by adjusting the level in the special Set-up menu on the instrument panel. Press the ESC, + and - keys to the right of the instrument panel.The dimmed lighting is managed differently according to the instrument panel fitted (COMFORT or MATRIX).In both trim levels the control panel is equipped with a brightness sensor that discriminates between night (night time) and day (daylight) conditions in order to suitably manage the lighting of the vehicle controls and displays.The dimmed lighting can be adjusted to 8 different levels of brightness.DAYLIGHT CONDITION with exterior lights switched on:The COMFORT display is lit at 100% and the brightness cannot be dimmed. The other displays are also lit to maximum intensity.The MATRIX display is illuminated to the previously set level. It can always be adjusted; the other displays are lit to maximum intensity.NIGHT TIME CONDITION with exterior lights switched on:The instrument panel display, radio and climate control displays and controls are lit at the set level of brightness.The brightness cannot be turned down to zero and the warning lights cannot be adjusted.For further details,The dimming value is transmitted by the instrument panel via the B-CAN to allow the set brightness value to be sent to the other control units.All the other controls are lit up when the ignition is on (INT).The function is managed by the Body Computer and the individual lines are protected by a fuse located inside it.

FUNCTIONAL DESCRIPTION - INSTRUMENT LIGHTING - Fiat 500 1.2 8v

Body Computer M001 (pins 18 and 20 of connector D) is connected via the B-CAN line to instrument panel E050 (pins 5 and 6), from which it receives the brightness intensity adjustment signal via the special buttons located to the right of the instrument panel and the daylight or night time condition information via its built-in sensor, to manage the dimming function.These signals are transmitted, also via the B-CAN, to radio P020 (pins A3 and A1 of connector A) and climate control control unit M070 (pins 10 and 9 of connector A), where fitted.Body Computer M001 receives a direct battery power supply (pin 1 of connector A) protected by fuse F01 in engine compartment junction unit B001 (pin 18 of connector B); it also receives an ignition-operated power supply (INT) at pin 11 of connector E.Body Computer M001 is also connected to driver-side dashboard earth C015 via pins 9 and 10 of connector E.The side lights activation signal is sent to pin 51 of connector D of Body Computer M001 from steering wheel interface H005.The side lights on power supply is sent by Body Computer M001, respectively:from pin 30 of connector F, to cigar lighter P070 (pin 1);from pin 60 of connector D, to radio wiring connector P020 (pins A6 of connector A);from pin 12 of connector B, to heater/air conditioner control lights G045.The ignition-operated power supply line (INT), protected by fuse F49 inside Body Computer M001, provides lighting respectively:from pin 17 of connector E, for clock spring junction radio controls D047 (pin 5);from pin 15 of connector E, for switch control unit H090 (pin 6);from pin 22 of connector C, for adjustable mirrors control H030 (pin 8);from pin 23 of connector F, for sunroof switch H060 (pin 4) and for convergence control panel H136 (pin 6);from pin 13 of connector E, for driver-side H042 and passenger side H043 front electric window switches (pin 4);from pin 16 of connector E, for auxiliary controls panel H115 (pin 6).
