Type-approval data review before eCoC generation
The purpose of a type-approval data review is to connect the individual vehicle with the correct approved configuration. A schema validator can check structure, but it cannot replace the manufacturer's review of the vehicle facts. Build the checklist around evidence and ownership rather than treating every non-empty field as correct.
Identify the approved configuration
Start with vehicle identity and the controlled approval reference. Compare the type, variant and version used by production with the homologation record. When two systems use different identifiers, preserve the mapping and its review owner. Do not rely on a descriptive model name to settle that relationship.
Keep common and vehicle-specific values separate
Mark which values come from a reusable vehicle template and which are determined for the individual vehicle. Record their source and revision. A template correction may affect multiple unissued candidates, while an individual correction may affect one. The team should be able to identify the affected records before regenerating outputs.
Preserve manufacturing-stage evidence
For a multi-stage record, show the earlier-stage reference and the values added or changed by the responsible later stage. A useful comparison sheet has source stage, reviewed value, applicability, evidence and reviewer columns. Treat an unresolved difference as work to be assigned; copying the base value into the completed record merely to remove a blank is not a review.
Distinguish missing from not applicable
Use separate outcomes for a value that is not applicable, a value not yet received and a value awaiting confirmation. Attach the actual applicability rule used for the destination mapping. This prevents reviewers from interpreting an empty cell differently and makes it easier to resolve recurring upstream issues.
Example: a correct format with the wrong reference
A fictitious candidate passes schema validation because the approval-reference value has an allowed format. The reviewer then finds that it belongs to another configuration. Correct the controlled record or mapping, identify other candidates using the same reference and regenerate the affected outputs. Preserve the original validation result: it explains that the structural check passed while the factual review failed.
Release checklist
- Vehicle and approval references reconcile across the named sources.
- Type, variant and version are reviewed for this vehicle.
- Applicable technical values and units have accountable sources.
- Stage differences and unresolved inputs have a disposition.
- The output candidate identifies the reviewed source revision.
- A reviewer is named for the decision to proceed to signing or sealing.
Use the actual IVI specification
EUCARIS links to the messagebooks and schema material used for IVI implementation. Translate the reviewed concepts into the actual required fields through a controlled mapping. The checklist above is a proposed review method, not a replacement for those specifications.
