FUNCTIONAL DESCRIPTION

The dipped-beam headlights activation signal is sent to pin 38 of connector D of Body Computer M001 from steering wheel interface H005.    See E2011 DIPPED HEADLAMPS 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:

  • from pin 11 of connector C, for left-hand headlamp motor (pin 6);
  • from pin 26 of connector C, for right-hand headlamp motor (pin 6);
The same dipped beams activated enablement signal reaches pin 8 of instrument panel E050 from pin 8 of connector E of Body Computer M001.Operating the buttons to the right of the instrument panel sends a command signal (pin 7 of E050) that operates the adjustment motors built into the two main headlights F010 and F011 (pin 7).Main headlamps F010 (left) and F011 (right) are connected to left-hand front earth C010.
