Freeze Frames guide

Use Freeze Frames to see whether diagnostic decode produced freeze-frame evidence and whether it has enough metadata for engineering interpretation.

What it provides

  • Freeze-frame count, decode status, diagnostic provenance, and linked technical artifacts.
  • A clear boundary between persisted freeze-frame records and later ODX/DTC catalog enrichment depth.
  • Links back to Diagnostics Data and Diagnostic Decode when enrichment inputs are missing.

How to use it

  1. 1. Review freeze-frame availability, diagnostic enrichment state, and the technical data needed for value/unit mapping.
  2. 2. Select a diagnostic-capable project log.
  3. 3. Confirm freeze-frame count and parser provenance.
  4. 4. Add or activate DTC/ODX/PDX context if value labels, units, or expected ranges are missing.

Outcome: Engineers know whether freeze-frame evidence exists and what context is required before reporting it.

NRC review context

Freeze-frame readiness

Freeze-frame records are counted from the latest offline decode. Value labels, units, and expected ranges depend on active DTC, ODX/PDX, CDD/CBF, or diagnostic specification context.

Missing

Decode run

Missing

Re-run processing for a diagnostic-capable log to create offline diagnostic evidence.

Freeze-frame records

Not found

No freeze frames were detected in the selected log.

Semantic enrichment

Needs data

Add DTC catalog or ODX/PDX style technical data before relying on semantic freeze-frame interpretation.

Freeze-frame records

Persisted diagnostic snapshots from the latest offline decode run. Values are reported from stored log evidence only.

TimeLabelValueDIDEnrichment
No freeze-frame records are available for the selected log. Re-run processing for a diagnostic log that contains stored freeze-frame or extended diagnostic data.

Diagnostic context artifacts

Active artifacts available to enrich freeze-frame and DTC evidence.
