A cleared lamp is not proof. Verification repeats the complaint conditions, the failed measurement, and any relevant monitor or self-test.
Why this matters
Understanding the system principle makes the test result more useful and reduces unnecessary disassembly or parts replacement.
Evidence to capture first
- Original symptom and test result
- Post-repair value under the same condition
- Code status and monitor readiness
- No new leaks, noises, or warnings
A disciplined path
- Record the before value
- Complete the repair
- Repeat the same load and test
- Document the after value and any follow-up requirement
Decision point
A road test must stay within legal and safe limits; use controlled equipment when the original condition cannot be reproduced safely.
