Step-by-step checks
- Verify VIN/market, production period, engine/energy and transmission identity first.
- Capture DTCs, freeze-frame, operating temperature, load and driver demand at the fault event.
- Compare HV/48 V, 12 V, DC-DC, cell deviation, thermal management and torque request on one timeline.
- Compare clutch slip, input/output speeds, mechatronic command and adaptations hot versus cold.
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.
