An Intelligent Diagnostic System for Distributed, Multi-ECU Automotive Control Systems 2005-01-1444

A modern automobile is becoming far more complex with the release of each new model. Complexity arises in the form of new mechanical devices, electronic devices and nowadays software components. With this increase in complexity, the job of diagnosing a fault is becoming increasingly difficult, as the service technician now requires detailed knowledge in a range of disciplines. This paper describes an Intelligent Diagnostic System (IDS) that was developed to intelligently diagnose faults in a multi-ECU (Electronic Control Unit) environment. Intelligence is achieved by diagnosing several faults while always attempting to isolate a “core” faulty component instead of simply returning a series of faults.
