ABSTRACT:
The invention provides a motor vehicle anti-theft system in which an authorization code, representing the access authorization, is transmitted via the vehicle starting line arranged downstream from the ignition switch, to a start release unit. A control unit for the engine start, previously in an engine-start-blocking condition, is thereby placed into a release condition, in which it transmits a start request (arriving from the starting line) to the starter motor. By using the starting line for transmitting the authorization code, it is achieved that the latter is coupled through a connection which is necessary for the start, and therefore cannot fail separately.
