Remote-Diagnostics becomes “Diagnostics 4.0“ – With more than 100 ECUs in the vehicle, pressure is increasing to ensure more efficient diagnostics of these ECUs. In parallel to this development, the dependence on ECU functions in many instances today makes reliable statements in diagnostics increasingly difficult – which means that the quality of diagnostics overall must increase. The answer to these challenges are called remote diagnostics and cloud diagnostics.

ODX (Open Diagnostic data eXchange) describes an XML format for exchanging diagnostic data. It contains both diagnostic specifics and flash data for individual ECUs, as well as information on accessing the entire vehicle network.

Information poster for free | OTX – Open Test sequence eXchange format OTX describes a sequence language for exchanging diagnostic sequences in the ECU life cycle. The actual linguistic scope (core) is tailored to the particular diagnostic application with standardized extensions, but is also easy to extend with proprietary solutions for other applications.

Information poster for free | DoIP – standardized vehicle diagnostics over Ethernet With Diagnostics over IP, diagnostic services introduced over UDS are used over TCP/IP and Ethernet. This enables much higher data rates than with CAN, representing great potential for savings both in terms of time and expenses in the case of complex diagnostic tasks and flash applications.
