Parse and review ODX and PDX content
Read the supplied ODX or PDX data, trace relevant diagnostic definitions, and identify inconsistencies or incomplete relationships affecting practical use.
Vehicle Diagnostics · ODX Review
Review ODX data before it becomes a diagnostic problem
Assess ODX and PDX diagnostic data against requirements and expected ECU workflows. The review focuses on usable findings around DIDs, DTCs, diagnostic sessions, routine control, and security access.
Discuss a ODX ProjectProblems I can investigate
Find the behavior behind the symptom
- 01
DID read failure
Investigate whether ODX descriptions, diagnostic sessions, service definitions, or related data can explain a DID read failure. Findings are documented with evidence rather than assumed root causes.
- 02
Diagnostic application needed
Turn reviewed diagnostic data and requirements into a clear basis for a purpose-built diagnostic application, data converter, or follow-on engineering activity.
What I can help with
Focused engineering work in Vehicle Diagnostics
Assess UDS diagnostic coverage
Examine how the data represents UDS services and concepts including DIDs, DTCs, diagnostic sessions, routine control, and security access.
Check transport and communication context
Review diagnostic assumptions across ISO-TP and DoIP where they are represented in the supplied data or requirements.
Relate data to implementation concerns
Compare diagnostic descriptions with requirements and relevant DCM behavior, using CANoe or CAPL when those artifacts are included in the engagement.
Prepare repeatable follow-on utilities
Convert or generate structured engineering outputs when the review identifies a need for a data converter or diagnostic application.
What to send
Start with the evidence you already have
ODX
The ODX diagnostic-data description to review, including the relevant scope and version information available to the project.
PDX
The PDX package containing the diagnostic data and related assets under review.
Requirements
System, software, or stakeholder requirements used to assess intended diagnostic behavior and data coverage.
How the analysis works
From recorded data to engineering findings
- 01
Scope the review
Confirm the supplied ODX, PDX, and requirements, then define the diagnostic data and use cases in scope.
- 02
Parse the diagnostic data
Read the supplied content into a usable representation and trace relevant definitions for ECU diagnostic workflows.
- 03
Analyze consistency and coverage
Compare the data with requirements and inspect DIDs, DTCs, diagnostic sessions, routine control, security access, and transport context where applicable.
- 04
Document evidence and gaps
Record findings with references to the reviewed data, distinguish observed issues from open questions, and identify practical follow-on work.
- 05
Agree next engineering output
Translate the findings into an engineering analysis, diagnostic application, or data converter when that is the appropriate next step.

FAQ
Practical questions before an investigation
- What can be reviewed?
- The review can cover ODX, PDX, requirements, and their representation of UDS diagnostic workflows, including DIDs, DTCs, diagnostic sessions, routine control, and security access.
- Can the review investigate a DID read failure?
- Yes. The analysis can trace relevant data definitions and diagnostic context, document evidence, and identify plausible gaps without claiming a root cause that the supplied artifacts do not support.
- Can you build software after the review?
- Where requirements and diagnostic data support it, the follow-on output can be a diagnostic application or data converter rather than only a written analysis.
- Do I need to provide a complete PDX package?
- Provide the ODX or PDX scope available for review together with the relevant requirements. Missing assets or unclear assumptions can be recorded as review findings.
