Fault Reported By Customer: "Large Sweep And Then Nothing"

If terminal 15 is switched ON and the headlights move through a large sweep and then remain in the straight-ahead position, the signal from the zero-position sensor is not being received.

If the zero-position sensor fails, the position of the headlights is determined via a mechanical reference point as follows: The swivel module moves as far as the permitted mechanical end stop (= "large sweep") and then into the straight-ahead position. The turning movement of the adaptive headlights is then deactivated (= "and then nothing").
