Classification: CPC B  H | IPC B  H

Claim 0:
1. An electronic component with ground coding for a motor vehicle, comprising:
a plurality of external ground connections for selectively connecting to a cable harness of the motor vehicle;
a plurality of internal ground connections, wherein each internal ground connection is electrically coupled to an assigned external ground connection so that the potential present at a respective internal ground connection corresponds to the potential present at the assigned external ground connection;
an evaluation circuit coupled to the plurality of internal ground connections and configured to determine at which first subset of the internal ground connections first signal information representing a reference potential as a first potential is present and at which second subset of the internal ground connections second signal information representing a supply voltage potential as a second potential is present in order to infer a coding of the component from the pattern of the internal ground connections supplied with the first and the second potential; and
a combination circuit configured to connect the plurality of internal ground connections to the plurality of external ground connections in such a way that, when a ground line of a cable harness is connected to precisely one of the external ground connections, the first signal information is present at a respectively different first subset of the internal ground connections in a predetermined manner depending on which of the external ground connections the ground line is connected to.
