ABSTRACT:
The invention is directed to a method of detecting and documenting exhaust-gas relevant malfunctions of a vehicle equipped with an internal combustion engine utilizing onboard equipment. Malfunctions are detected by a sensor device and evaluated in a circuit unit. The malfunction is displayed by a warning lamp (fault announcement) and is stored in a fault memory. A pressure measurement in the fuel loop is made and the output as well as the storage of the fault announcement is made in dependence upon the measured pressure. This is done to differentiate fault announcements based on a fuel tank run to empty.
