Claim 12:
13. A method for testing a function of an antenna system, the antenna system containing a plurality of antenna units, wherein each of the antenna units having an antenna and at least one resistor interconnected in each case between an assigned input of a selection unit and a specific one of multiple outputs of a further selection unit, which comprises the steps of:
providing a computing unit programmed to:
provide a control signal for the selection unit and the further selection unit at a first output, wherein the control signal defines which input of the selection unit is to be connected to an output of the selection unit and which of the outputs of the further selection unit is biased with a bias voltage applied to an input of the further selection unit; and
receive an antenna signal present at the output of the selection unit at an input of the computing unit;

controlling a diagnostic circuit;
inferring a fault in the antenna system from a comparison of antenna signals at the output of the selection unit that are determined when the diagnostic circuit is activated and not activated.
