Access to diagnostic data from Electronic Control Units (ECU) in vehicles is of great importance in the automotive industry, both from a life cycle support perspective and during product development. Through diagnostic services, the state-of-health of components and subsystems can be monitored to detect and prevent failures by means of predictive maintenance, which improves operational availability and lowers support costs. For pre series test vehicles, diagnostic services are crucial to be able to track problems as early as possible in the development process, preventing serious faults to pass undetected into production vehicles or as a tool during verification and validation activities. In the aftermarket, diagnostics form an important part of the service and maintenance process, with Diagnostic Trouble Codes (DTC) routinely being read out from customer vehicles during service for state-of-health monitoring and fault tracing. Automotive manufacturers rely on diagnostic systems to improve customer satisfaction by increasing the service technicians' ability to diagnose and remedy problems in the increasingly complex electronically controlled vehicles. As an added value for the automotive manufacturer, the diagnostic data retrieved during service can be uploaded to the manufacturer's database over the Internet. Statistical analysis of collected DTCs is important to monitor the quality of components and subsystems, to prioritize in which order problems should be addressed and to find correlations between different faults, or between faults and the operating environment.
