Abstract
An electric wiring system of a motor vehicle with several control devices that communicate with each other via a data bus, and with an immobilizer is provided. In order to create an electric wiring system of a motor vehicle that includes an immobilizer with high reliability the immobilizer includes at least a first and a second control device from the plurality of control devices and an authentication apparatus, in particular an authentication control device. The authentication information of the plurality of control devices is supplied via the data bus to the authentication apparatus. The authentication cancels the immobilizer of the vehicle when the authentication information transmitted from the first and the second control device corresponds to the authentication information expected for the particular control devices.
