Abstract
The invention is directed to an on-board diagnostic method wherein a fault is detected but is only registered as a fault when a delay time span has elapsed since its first-time occurrence in an operating phase of an internal combustion engine and when the fault then still continues to occur. The delay time span is measured on the consumption of the quantity of fuel which the vehicle can still consume for an almost empty tank. In this way, detected faults, which are attributable to an empty tank, are not registered.
