The dipped headlamps activation (earth) signal - and any AUTO function - is sent to pin 2 of connector I and to pin 28 of connector G of the Body Computer M1 from the steering column switch unit H5 See E2011 DIPPED HEADLAMPS The Body Computer M1 controls the supply for the dipped headlamps sending an earth signal to relay T1 in the junction unit under the dashboard B2 from pin 8 of connector F of M1 which energizes relay T1: the latter supplies the dipped headlamps - pin 2 for the lamps F10 (left) and F11 (right); at the same time it provides the enablement for the adjustment motors - pin 6 for lamps F10 (left) and F11 (right);Each circuit is protected by a fuse in the junction unit B2 : F13 for the left headlamp and F12 for the right.The control for the headlamp adjustment, located in the unit to the left of the steering wheel H90, also receives the enablement supply - pin 5 of connector A, whilst a control signal produced by the adjustment potentiometer - pin 15 of connector B is sent; this control signal "passes through" the junction unit under the dashboard B and activates the adjustment motors built into the headlamps - pin 7 for the (left) lamps F10 and F11 (right).
