FUNCTIONAL DESCRIPTION - FOG LIGHTS - Fiat 500 1.4 16v
The fog lights activation button, located on the switch controls unit H090, receives a reference earth from pin 37 of connector D of the Body Computer M001, and sends the function engagement signal to pin 45 of the same connector.Body Computer M001 receives power direct from the battery (pin 1 of connector A) protected by fuse F01 of engine compartment junction unit B001 (pin 18 of connector B); however, this is powered when the ignition is on (INT), to pin 11 of connector E.Body Computer M001 is powered when the ignition is on (INT/A) at pin 1 of connector E, excluding the fog lights system during start-up.Body Computer M001 is connected to the 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 the M001 Body Computer from the H005 steering column switch unit.Body Computer M001 (pin 4 of connector B) controls fog light activation by sending an earth signal to the relay coil T14 of the engine compartment junction unit B001 (pin 54 of connector B). The coil of T14 is powered when the ignition is on by the line (15/54) protected by fuse F87 of B001.This earth signal excites relay T14: it supplies the left fog light F015 and the right fog light F016 via the line protected by fuse F30 of control unit B001 (pin 53 of connector B).The fog light clusters are connected to the left front earth C010.Body Computer M001 is connected, via the B-CAN line, from pins 18 and 20 of connector D, to instrument panel E050 (pins 5 and 6) to manage the fog lights warning light.
