OBD goes ODX: Architecture of the ODX database for MVCI-based OBD Scantools
The XML-based data format ODX (Open Diagnostic Data Exchange) is standardized in ISO 22901 and used for the machine-readable and executable description of diagnostic protocols. OBD Scantools that process ODX data are based on the MVCI technologty as it is standardized in ISO 22900. This presentation starts with a short introduction to ODX and MVCI. It focuses on how the OBD communication protocols SAE J1979, SAE J1939 (HD OBD), ISO 27145 (WWH-OBD), and SAE J1979-2 (OBD on UDS) are mapped to the ODX architecture.
