DESCRIPTION - HEADLAMP AGLINMENT CORRECTOR - Fiat 500 1.4 16v
The adjustment of the orientation of the headlamp light beam according to the load is carried out by means of a regulating device (located inside the main headlamps), which tilts them appropriately, lowering the light beam if the vehicle is heavily laden and raising it if the load lessens.The headlamp alignment correction system can only be activated with the ignition key in the MAR position and the dipped beam headlamps switched on.Two buttons to the right of the instrument panel allow the headlamp alignment to be adjusted, allowing the vertical orientation to be changed between 4 predefined positions (from 0 to 3):
FUNCTIONAL DESCRIPTION - HEADLAMP AGLINMENT CORRECTOR - Fiat 500 1.4 16v
The dipped-beam headlights activation signal is sent to pin 38 of connector D of Body Computer M001 from steering wheel interface H005.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.Body Computer M001 manages the power supply to main headlights adjustment motors F010 (left) and F011 (right) as well as the activation of the dipped beam headlights. Each circuit is controlled by a dedicated relay built into the Body Computer and is protected by fuse F13 of the Body Computer; respectively:
