Research focus: verify platform/generation, powertrain/energy/driveline and market-specific application identity against manufacturer/source records before applying parts, service procedures or chronic-fault claims.

System map

• HV battery, BMS, isolation, inverter, OBC/DC-DC, 12 V and thermal management are separate evidence chains.

Measurement and verification sequence

1. During READY/charging, monitor pack temperatures, cell delta, isolation, 12 V and charging-power curve together.

Misdiagnosis traps

• Displayed range or one SoH value alone does not prove battery health.

Variant-specific system split

• Control chain is separated as power/ground → network communication → sensor input → ECU/TCU command → actuator → physical result.

Freeze frame / live data

• Freeze frame: first/last fault time, RPM, load, vehicle speed, system voltage, core temperatures and companion DTCs.

Root-cause split

• Prove the same symptom separately across power supply, network communication, sensor feedback, actuator response and mechanical result branches; one DTC is not a parts diagnosis.

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.
