An electric starter motor (110) is arranged so as to start a combustion engine (120). The function of the starter motor (110) is subject to diagnostics by means of measuring elements (130, 140) that measure a supply voltage (U) to the starter motor and an rpm (RPM) of the combustion engine. Based on the measured parameters (U, RPM), a processor (160) determines a status indicator (S) that provides a quality metric for the performance of the starter motor (110). A storage element (170) stores a respective value for the status indicator (S) in connection with a number of activations of the electric starter motor (110) in a data series (M). The processor (160) analyzes the data series (M) and determines, on the basis thereof, whether the function of the electric starter motor (11) is acceptable and, if the function is not determined to be acceptable, generates an error code (E). |
