Circuit for motor vehicles with coding plug
First Claim
1. A system for a motor vehicle for characterizing one of multiple variants of an electrically controllable subassembly, the system comprising:
- a coding plug connectable to the subassembly; and
an analyzer unit with a measurement input connectable directly or indirectly to at least one electric terminal of the coding plug, wherein the coding plug has a fixed electric wiring arranged such that a defined electric state is generable at the measurement input of the analyzer unit, and wherein the electric state is detected by the analyzer unit and compared with stored data such that a defined electric state differentiable from all other states is assigned to each possible variant of the subassembly.

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.

11. A method for a motor vehicle for determining a variant of an electrically controllable subassembly, the method comprising the acts of:
-
connecting an analyzer unit with a measurement input to at least one electric terminal of a coding plug;
assigning a defined electric state differentiable from all other states to each possible variant of the subassembly;
detecting a generated defined electric state; and
comparing the detected defined electric state with the assigned defined electric states to determine a variant of the subassembly. - View Dependent Claims (12, 13, 14)
