The Term ODX

Diagnostic Data Format ODX

Standardized diagnostic data format (ISO 22901-1)

for test devices

and ECUs

ODX means Open Diagnostic Data Exchange

Intentions of ODX

Data reuse in Development, Production, Service (Single Source)

Vehicle diagnostics

Machine readable

Data model close to process responsibilities

Acceptance and Coverage

ODX in Processes and Tools

Acceptance and coverage is good!

Harmonization of tool chains. ODX based tools can be “easily” exchanged.

ODX simplifies the diagnostic tool landscape.

ODX provides good support for UDS.

Introducing ODX results in a win-win situation for OEMs and suppliers.

supports all diagnostic use cases at OEM and supplier. ODX

Flexibility and Complexity

ODX in Processes and Tools

Interests and requirements to vehicle diagnostics are complex.

Flexibility requires to cope with complexity.

Authoring guidelines reduce flexibility and complexity of ODX via

Selection of feature and

Defining Content

They describe further syntax and diagnostic semantics

Intention: Automatic (re)use of data in ODX consuming processes
