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.

What is claimed is: 1. A method for treating errors in an electronic control unit of a vehicle, the electronic control unit being programmed with an error-recognition program and including an error memory for storage of permanent and sporadic errors and an error indicator, the method comprising the steps of: writing into the error memory at least one error detected when the vehicle starts to move; when the at least one error recurs, incrementing the count of an error counter allocated to the at least one error in the error memory by a preselected amount; when the vehicle starts to move on a subsequent occasion, the count of the error counter reaches a preselected value for the at least one error, launching a poor maintenance program; and using the poor maintenance program to prevent damage to the vehicle by disabling the start of a vehicle function associated with the at least one error until expanded tests have been performed and passed. 2. The method according to claim 1, further comprising the step of deleting at least one of all and part of the count of the error counter when the vehicle has been driven for at least one of a preselected time and a preselected distance without errors. 3. The method according to claim 2, further comprising the step of decrementing the count of the error counter by a preselected amount when a part of the count of the error counter is deleted. 4. The method according claim 1, further comprising the step of enabling the start of the disabled vehicle function when the count of the error counter reaches zero.
