Patent ID: 8862309

Claim:
A method for diagnosing and/or adapting at least one system ( 12 , 14 ) of a device ( 10 ), characterized in that said method comprises: (a) changing at least one manipulated variable ( 44 ) of a first system of the at least one system ( 12 , 14 ) of the device ( 10 ) with respect to a currently present value of the manipulated variable ( 44 ); (b) determining at least two state variables ( 46 ) of a second system of the at least one system ( 12 , 14 ) of the device ( 10 ); and (c) making a decision ( 61 ) about the further execution of the method as a function of the at least two state variables ( 46 ) characterized in that in step (c) the further execution of the method comprises at least one of the following measures: refined and/or repeated diagnosis of one of the systems ( 12 , 14 ) or of a system component ( 47 ) which is contained therein and which is supposed to be faulty; changing of a diagnostic algorithm ( 65 ) as a function of the at least two state variables ( 46 ) which are determined; selection of alternative diagnostic algorithms ( 65 ) from a stored supply ( 64 ) as a function of the at least two state variables ( 46 ) which are determined; changing of the sequence of individual diagnostic steps of a diagnostic algorithm ( 65 ); changing of the sequence in which the systems ( 12 , 14 ) and/or system components ( 47 ) are checked; and unchanged continuation of the diagnostic method.
