Abstract

In a method for self-diagnosis of a system for seat occupancy detection, in particular for self-diagnosis of a HOBBIT system, a self-diagnosis signal that has been modulated in a predetermined manner is transmitted by the transmit unit to the receive unit of the base station and analyzed, preferably with the reflectors deactivated. From the analysis it is possible to make deductions about the operational integrity of the base station.
