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.
UDS (Unified Diagnostic Service) is based on the standards KWP2000 for K-Line and CAN. It was developed with the goal of standardizing different implementations of the predecessor standards and new requirements stemming from further developments in technology and new standards to form one generally valid diagnostic protocol. UDS describes the layer 7 protocol (diagnostic services) but is based on an extended version of the diagnostic protocol of KWP2000 on CAN (ISO 15765-2).
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.
You want to know all about diagnostic programming, flash programming and ECU communication fast without having to spend lots of time studying relatively “dry” vehicle protocols? Softing can make it happen.
