Abstract
In a diagnostic system, messages which have occurred are collected and buffered with a short diagnostic test which is implemented in a control unit onboard the vehicle. The collected data are then transmitted into a memory area of the portable electronic driving authorization record, which therefore always contains the result of a short diagnostic test which has been carried out onboard. The result of this short diagnostic test is read out from the memory of the driving authorization record with a computer system in the customer reception of a servicing workshop, and is processed with a more wide-ranging diagnostic algorithm which builds on the result of the short diagnostic test.

5. A diagnostic system for motor vehicles having electronic driving authorization records, said diagnostic system having onboard components and offboard components, with the onboard components being connected to one another via communication links, and the offboard components having a communication link to one another;
- wherein,
at least one of the onboard components implements a short diagnostic test, which collects and buffers diagnostic data onboard; said diagnostic data are transmitted to a memory area in an electronic driving authorization records component, and stored; and said diagnostic data are read out again from the electronic driving authorization records component with the offboard components of the diagnostic system, and processed further. - View Dependent Claims (6, 7, 8)

9. A method for diagnosing systems in a vehicle having onboard components that communicate with each other via a first communication link, said method comprising:
-
at least one of said onboard components performing a short diagnostic test, which collects and buffers diagnostic data on board the vehicle; transmitting said diagnostic data to a memory area in a transportable electronic unit that stores electronic driving authorization records for said vehicle; offboard data processing components reading said diagnostic data out of said transportable electronic unit, and processing said diagnostic data further. - View Dependent Claims (10, 11, 12)
