184001909 - E2010 SIDE LIGHTS/NUMBER PLATE LIGHT - FUNCTIONAL DESCRIPTION

Operational description

Two signals (earth) are sent from the steering wheel stalk unit H5 to the Body Computer M1 that manages both side lights and low beams in manual or AUTO mode (automatic dusk sensor activation).The "Light 1" signal is sent from pin 28 of connector G of Body Computer M1 from stalk unit H5, pin 7 of connector C.The "Light 2" signal is sent from pin 2 of connector I of Body Computer M1 from stalk unit H5, pin 8 of connector C.The side lights are activated in manual mode when the Light 1 signal is not present and the Light 2 signal is present.The side lights are activated in AUTO mode when the Light 1 signal is not present and the Light 2 signal is not present.If both signals are present, the lights are permanently off.The side lights are automatically activated by the dusk sensor K125 (signal via the A-BUS line at pin 7 of connector D of M1); the dusk sensor K125 receives a supply from the INT line protected by fuse F49 of junction unit B2.The lights are also activated by the parking lights button located in the left switch unit H91 which sends an earth signal to pin 17 of connector H of M1.The Body Computer M1 controls the supply for the front side lights F10 (left) and F11 (right) from pins 40 and 30 of connector B, for the rear side lights F30 (left), F31 (right) and the number plate lights F50 and F51 from pins 5, 6, 9 of connector D and 38 of connector E.The Body Computer M1 is connected, via the CAN line, to the instrument panel E50 to manage the "side lights on" warning light and, if there is a problem detected in the circuit or the bulbs, the "lights failure" warning light. if there is a fault in the dusk sensor, the "general failure" warning light.
