Research boundary

This dossier is not an OEM failure-rate claim. Identity, source level, measurement and market/generation scope are verified separately.

Step-by-step technical approach

1. Define symptom reproduction conditions and capture baseline event data.
2. Use electrical measurement, live data and physical testing together, not as substitutes.
3. Perform comparative post-repair verification under the same condition.
4. Use the DTC as a starting signal for measurement, not the cause by itself.
