The standard mix does it: Diagnostics with AUTOSAR and ODX – Part 2: ODX in the AUTOSAR development process The Open Diagnostic data eXchange (ODX) format is an XML-based data format for describing the data relevant to vehicle diagnostics. ODX was conceptualized as an open format for exchanging diagnostic data between automotive OEMs and their suppliers. AUTOSAR is the future-oriented reference architecture for ECU software. Clearly specified interfaces, standardized behavior and XML-based data formats are key features of the AUTOSAR standard. This is the second article of the “Diagnostics with AUTOSAR and ODX” series, and it addresses the topic of ODX and how available ODX data can be profitably integrated in AUTOSAR development.
