In a method for the plausibility check of the shut-down time of a motor vehicle with an internal combustion engine for a subsequent diagnostic process, it is proposed that after the internal combustion engine is turned on, a first control device for the internal combustion engine of the motor vehicle determines a first shut-down time T1, which is limited to a specified run-on time TN, and a second control device of the motor vehicle determines a second shut-down time T2, whereby the difference DeltaT is formed from the first shut-down time T1 and the second shut-down time T2, and the second shut-down time T2 is found to be plausible if the difference DeltaT lies within a range that is defined based on the first shut-down time T1 or the run-on time TN. In accordance with the proposal, a simple plausibility check of the second shut-down time T2 is performed and the conditioning of the internal combustion engine can be examined based on this second shut-down time T2, and optionally a diagnostic process can be started.
