Abstract
The diagnosis of an open-circuit fault or of a short-circuit in an ignition system is effected by performing asynchronous periodic extraction of samples of current in a switch. A check is made to ensure the satisfaction of certain temporal conditions in respect to a moment of extraction of the samples and comparing the samples, on the basis of that the temporal conditions are satisfied, with predetermined fault threshold values.
