Diagnostic Tool Set – Reliable communication in the vehicle

All the major vehicle manufacturers worldwide, together with their suppliers, worked on specifying and implementing a range of international standards. A standardized diagnostic runtime system is a central element in vehicle diagnostics. This ISO MVCI server makes it possible to use vehicle interfaces (VCIs) from different manufacturers and exchange them at will. The standardized data format for specifying and exchanging diagnostic data is ODX. It is independent of the bus protocols used and comprises not only the vehicle- and ECU-specific diagnostic functions ("services") but also configuration and flash data. All ECU variants, based on a standard variant, are included. Redundancies are avoided with the use of libraries, inheritance and references. The actual applications  use the methods made available at the application interface. This means that they can be created without there being any need for users to have special knowledge of communication protocols or services and that they are independent of VCI and the protocols used. ECU and vehicle information is accessed using the conversion methods, service and data type descriptions contained in the ODX database. It is also possible to address a request to all ECUs of a functional group with comprehensive functionality, such as for example OBD.
