Educational case studyIntermediateEvidence-led
An intermittent wheel-speed dropout followed harness movement near a steering stop, while the sensor itself produced a clean signal.
Why this matters
The value of this case is the order of evidence and the verification step. The same symptom on another vehicle may have a different cause.
Evidence to capture first
- Four-wheel speed graph
- Harness movement
- Circuit continuity under flex
- Routing and clip condition
A disciplined path
- Reproduce at low speed
- Inspect full steering travel
- Isolate the damaged section
- Use an approved sealed repair and restore routing
Decision point
The signal remained stable through steering and suspension travel after the harness repair.
