Step-by-step checks

1. Record battery/12 V rest, crank and loaded voltage together with alternator or DC-DC behaviour.
2. Measure loaded voltage drop at ECU powers and grounds, not only open-circuit continuity.
3. Scan all modules; compare timestamps and shared U-code clusters rather than one module DTC.
4. On CAN, inspect resistance/voltage and when needed dominant-recessive waveform, reflections and noise with a scope.
5. Compare sensor signal with ECU live data and, where possible, a physical reference measurement.

How to verify the result

Do not make a parts decision from one DTC, sensor value or symptom. Reproduce the fault under the same temperature/load conditions and verify commanded-versus-actual data, electrical measurement and physical result together. Exact OEM limits should only be used when matched to the correct variant service source.
