XML-based format for the standardized description of diagnostic data and services.

ODX stands for Open Diagnostic data eXchange and is the common name for ASAM MCD-2 D. It describes diagnostic communication, DTCs, parameters, flashing, variant coding, and other ECU diagnostic capabilities in a standardized XML data model. In the logging and diagnostics world, ODX is important because it serves as a single source for testers, diagnostic servers, and documentation.
