Patent number: 12037060Abstract: A method for diagnosing a functionality having an input or output signal with discrete values or discrete classes of values which are observable quantities of a diagnosis functionality. The signal to be diagnosed is the input or output signal, where the values or classes of values have a cardinality N, where N error counters are provided. The method includes providing a sum signal from the sum of the signals of the error counters. When a value or a class of values is erroneous, the method includes incrementing the signal of the error counter assigned to the erroneous value or the erroneous class.
