A procedure for checking the operational capability of an electric circuit, which has a sensor module and a diagnosis mechanism with the sensor module including an integrated switching circuit, wherein the sensor module has at least one output terminal connected to the diagnosis mechanism and power supply terminals, and wherein an operating voltage is applied via cables to the power supply terminals. The sensor module is switched to a test mode, in which a communication test signal is emitted from the output terminal. This signal is read in by the diagnostic mechanism and compared with a tolerance band range, in order to verify that the communication with the sensor module is operational. In the event of operational communication, the operational capability of the switching circuit is tested. |
