Abstract
A combination () of a power-supply control device () and at least one light-control device () of a motor vehicle operates at least one semiconductor light source (). The control device () supplies the light-control device () with power via a supply line () connected to a first connection pin () of the control device (), monitors current flowing through connection pins of the control device (), and makes use of diagnoses thereof. The light-control device () is connected to an additional connection pin () of the control device () via an error line () and checks function of the connected semiconductor light source () and, in the case of a malfunction, triggers a current flow in the error line (). The control device () reacts to the triggered current flow with generation of an error message.
