System map

• ICE, HV/48 V, 12 V, DC-DC, motor-generator, regeneration and thermal management are layers of one energy chain.
• Read clutch, mechatronics/TCU, actuator pressure, input/output speeds and adaptations together.

Measurement and verification sequence

1. Compare SoC, cell deviation, DC-DC output, motor torque request, regeneration and ICE engagement conditions in one capture.
2. Record cold/hot shifts, slip, input/output speed delta and actuator/line-pressure behaviour.

Misdiagnosis traps

• A single DTC or user symptom is not a parts diagnosis; confirm with measurements and physical evidence.

Variant-specific system split

• ICE, 12 V, HV/48 V, DC-DC, motor-generator and thermal management are separate control layers; energy flow is aligned with the fault event.
• For DCT/DSG, TCU-mechatronics, K1/K2 clutches, actuator/line pressure and input/output speeds are evaluated together.

Freeze frame / live data

• Freeze frame: first/last fault time, RPM, load, vehicle speed, system voltage, core temperatures and companion DTCs.
• Electrified layer: SOC/SOH where available, cell delta, pack temperatures, HVIL/isolation, contactor permission, DC-DC output and 12 V voltage.
• Driveline: input/output speeds, commanded/actual ratio, clutch/TCC slip, fluid temperature, actuator/solenoid command and adaptations.

Root-cause split

• For READY/charging faults, separate 12 V supply from the HV permission chain first; low 12 V can mimic contactor/HVIL/isolation faults.
• For battery performance, use cell delta, temperature spread and voltage deviation under load/charge instead of one SoH percentage alone.
• For DCT harshness/slip, separate TCU command from clutch slip and actuator/hydraulic response; adaptation result alone does not prove mechanical wear.

What should be verified first?

Model name alone is insufficient. Do not generalize parts fitment, chronic issues or service procedures until production period, market, platform/generation, powertrain, transmission and controller identity are matched.
