ABSTRACT:
The invention is directed to a method of handling erroneous messages in a data processing arrangement. The data processing arrangement can be applied to a motor vehicle and includes at least two stations such as a motor control computer, a transmission control computer, and/or a brake control computer. A data line connects the two stations for transmitting messages. The method is performed by causing the station which detected the erroneous message to transmit an error report in response to the erroneous message; and, causing the error report to include a sequence of states or bits which cannot be confused with any sequence of dominant states or bits during error-free data transmission.
