A method of and a device for a self-diagnosis of setting members in complex controlling and regulating systems, particularly for the self-diagnosis of an idling speed air charge adjustor of an internal combustion engine, includes the following functional stages: the self-diagnosis is performed at certain operational conditions at which a regulating path governed by a regulating subsystem pertaining to the setting member does not react to a change of the latter and the operation of a motor vehicle thus remains unaffected; the comparing of plausibility of the control signals for the setting member with a second control signal from another regulating subsystem is performed by comparing both control signals with a known, previously determined relation, which is stored in a memory.
