US Patent 7647145 Method for error processing in electronic controllers

A method for error processing in electronic controllers, particularly, in motor vehicles, is provided whereby errors determined on each vehicle start are permanently written in an error memory. On repeated recognition of similar errors, an error counter, provided for the error, is increased. In the case where it is determined that the error counter has reached a pre-determined state on a renewed vehicle start, a special “poor maintenance” is launched, which only permits the start of the monitored function when further tests are carried out and completed.
