Signals that produce evidence
- Command, feedback, supply, ground and physical response belong in one measurement plan.
- Do not conclude from static measurements without reproducing the fault condition.

System operation and failure analysis
Separate similar symptoms
- Test mechanical binding, electrical loss and software/calibration effects as separate hypotheses.
Prove the repair is complete
- Reproduce the original fault condition.
- Check pending/permanent codes and monitor status.
- Verify no new network or low-voltage codes appear in related modules.
Overview
ISO 26262 functional safety is treated as a connected engineering topic rather than an isolated definition. Hazard analysis, ASIL, safety goals, architectural mechanisms and verification for automotive electrical and electronic systems.
