Abstract

A vehicle security arrangement includes at least one functional control unit, which provides a first code word; a theft protection control unit, which is coupled via a bus to the at least one functional control unit; and at least one input unit, which transmits to the theft protection control unit a second code word which the theft protection control unit forwards to the at least one function control unit. The theft protection control unit may initiate the provision of the first code word and the second code word. In the at least one functional control unit, a comparison of the first code word of the at least one functional control unit with the second code word takes place. In case of agreement between the first code word and the second code word, the at least one functional control unit enables itself.
