Functional description

The front fog lamps F15 (left) and F16 (right) are supplied through the front fog lamps relay R5 located in the relay unit B3 . The relay is supplied directly from the battery through the fuse line F3 of the relay unit B3 . The operation of the front fog lamps is also controlled by the electronic Check device M45 , which receives the control signal from the switch and controls the bulbs. Check device M45 is supplied directly from the battery. (maxifuse CENTR of B5 ) to pins 1 and 6 of connector C, via fuse F11 of junction unit B1 . An ignition-operated power supply (INT/A) reaches pin 9 of connector C through fuse F1 of junction unit B1 : pin 7 of connector C is earthed. The device M45 receives as an input the signal for the front fog lamps switched on from the button located in unit H35 - pin 2 of connector A: this signal only arrives when the side lights are on. In response to this signal, the device M45 sends - from pin 1 of connector D - the command to the front fog lamps relay R5 of B3 . At the same time it sends: from pin 7 of connector B - a signal to unit H35 so as to light up the LED near the button which indicates the 'front fog lamps on' function. The supply for this LED for H35 is controlled by the ignition (INT/A) via fuse F5 of junction unit B1 ; this line allows the control panel H35 to be lit up when controlled by the ignition (INT/A).
