Vehicle systems, especially the ECU networks, are getting more and more complex. In combination with that the diagnostic requirements are also increasing. This leads also to increasing efforts in development, production and service for diagnostics. The diagnostic functionality using proprietary diagnostic description formats for specification, software development, production, tester configurations and documentation is hardly controllable any longer. Therefore the use of standardized electronic description formats for diagnostics and flash programming data in all areas is essential. According to this background the "Open Diagnostic Data EXchange"(ODX) was created and today standardized in ISO 22901. This machinery readable exchange format based on XML ("extensible Markup Language") offers re-usable and inheritance concepts which open the possibility also to describe ECU variants, e.g. different software revisions. The challenge to introduce of ODX formats for system suppliers as ZF Friedrichshafen AG is to fulfill all different requirements of vehicle manufacturers for ECU diagnostics to data formats and software tools. In addition to ODX also other formats like CDD ('CANdela Diagnostic Data' file format defined by company 'Vector Informatik GmbH') or proprietary formats like XLS ('Microsoft Excel') or XML are requested by the vehicle manufacturers. Hence at ZF Friedrichshafen AG a specific CDD template was defined which allows the transfer of ZF specific data descriptions to the individual vehicle manufacturer defined data formats. By means of ODX export features in tooling a re-use in different standardized ODX tools and other formats is possible.
