Patent ID: 8452485

Claim:
A method comprising the acts of: placing a detecting control unit, upon detection of an error, into an error state and outputting an error message to a second control unit; receiving, by the second control unit, the error message, and determining, based on at least one predefined condition, whether to request the detecting control unit to prepare an error entry or cancel the error state; wherein when it is determined, by the second control unit, based on the at least one predefined condition, to request the detecting control unit to prepare an error entry, the second control unit outputs the request to prepare an error entry to the detecting control unit, the detecting control unit receives the request to prepare the error entry and the detecting control unit initiates entry of the error into a memory, wherein the entry of the error into the memory is performed by the detecting control unit or a third control unit, wherein when it is determined by the second control unit, based on the at least one predefined condition, to cancel the error state, the error state of the detecting control unit is canceled, and wherein the detecting, second, and third control units are connected to a data bus in a motor vehicle.
