Abstract
A circuit arrangement for motor vehicles for characterizing one of several variants of an electrically controllable subassembly is provided. A subassembly is connectable to a coding plug. The coding plug has at least one electric terminal which is directly or indirectly connectable to a measurement input of an analyzer unit. The coding plug has fixed electric wiring by means of which a defined electric state may be generated at the measurement input in the analyzer unit. The electric state is detected in the analyzer unit and compared with stored data, by means of which a defined electric state that can be differentiated from all other states is assigned to each possible variant of the subassembly.
