Method for detecting and documenting exhaust-gas relevant malfunctions of a motor vehicle having an internal combustion engine with the aid of on-board means |
摘要 |
The invention is directed to a method for detecting and documenting exhaust-gas relevant malfunctions of a vehicle having an internal combustion engine and a fuel tank utilizing on-board diagnosis. In the method, malfunctions are detected utilizing a sensor device and the malfunctions are evaluated in a circuit unit with the malfunctions including those malfunctions which are based on an empty tank. The fault announcements of the malfunctions are stored in a memory in dependence upon a pregiven number of drive cycles. A fill-level value indicative of the level of fuel in the fuel tank is determined and stored in the memory. Fault announcements of the malfunctions are outputted and stored in the memory in dependence upon the fill-level value thereby eliminating fault announcements of the malfunctions based on an empty tank.
