Where should diagnosis start?
Evaluate HV/12 V boundary, battery thermal management and energy flow together.
Check charging, HV isolation, 12 V supply, thermal management and software state as separate evidence chains.
Compare common-rail pressure, air path, EGR/DPF/SCR and turbo control under the same load condition.
For AWD/4x4 variants, verify transfer/differential, tire circumference and torque distribution control separately.
Exact OEM torque, pressure, capacity, pin or calibration values are not inferred from this normalized identity record; a verified service source is required for the exact vehicle application.

D · source-lineage identity; not OEM service evidence
Grade-D records are not OEM service procedures; they are source-lineage research rows preserving market/generation/powertrain identity. Exact torque, pinout, pressure or fitment is not inferred from this layer.
System architecture: what does this record indicate?
Fuel path is separated into low-side supply → high-pressure pump → rail → injectors; air path into MAF/MAP → turbo control → intake manifold.
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.
In an EV, HV battery/BMS, contactor-HVIL/isolation, inverter-motor, OBC/DC-DC, 12 V and cooling circuits are separate evidence branches.
In AWD/4x4, tire circumference, transfer/differential, wheel speeds and torque-distribution request are kept as separate mechanical/electronic evidence.
Freeze-frame and live-data package
Freeze frame: first/last fault time, RPM, load, vehicle speed, system voltage, core temperatures and companion DTCs.
Live data: rail target/actual, low-side supply where supported, MAF/MAP, boost target/actual, EGR command/feedback.
Electrified layer: SOC/SOH where available, cell delta, pack temperatures, HVIL/isolation, contactor permission, DC-DC output and 12 V voltage.
Chassis/traction: four wheel speeds, steering angle, yaw/acceleration and AWD torque request/feedback on the same time base.
Measurement sequence
1) Match vehicle/generation/market/powertrain/driveline identity to the source record; family name alone is not fitment evidence.
2) Preserve freeze frame and companion DTCs before clearing; make the first-fault condition reproducible.
3) Verify power/ground and network communication under load; do not decide from key-on static measurement alone.
4) Compare commanded air/fuel/pressure with an independent physical result; separate sensor bias from real performance loss.
6) After repair, recreate the same load/temperature and verify DTC state, live-data deviation and user symptom together.
Root-cause discrimination matrix
If rail pressure is low, separate low-side supply from high-pressure generation: when physical low-side supply is healthy but rail cannot follow target, regulation/pump/injector-leakage branches gain weight.
For low boost, do not jump to turbo replacement: separate MAF/MAP plausibility, charge leak, VGT/wastegate command and exhaust backpressure at the same load point.
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 AWD binding/warning complaints, exclude tire-circumference or wheel-speed mismatch before condemning transfer/differential hardware.

System architecture and component relationships
Split diagnosis into combustion-engine, power-electronics/PCU, traction motor-generator, HV-battery and 12 V/DC-DC layers; a supply or thermal event in one layer can create secondary DTCs elsewhere.
Time-align engine speed/load with battery SOC/temperature, motor-generator torque request/actual and system voltage; engine-only data can miss the hybrid torque path.
Where an electric AWD rear axle is fitted, correlate front/rear drive torque request, wheel speeds and stability-control intervention.
DTC / SPN-FMI / symptom discrimination map
For a hybrid warning verify 12 V and DC/DC supply first, then branch HV interlock/isolation, battery and inverter-motor DTC groups separately.
For low power compare engine torque with electric-motor assistance at the same speed/load; do not confuse SOC/temperature system limits with a mechanical engine fault.
For regeneration/brake-feel complaints correlate brake-ECU request, regen torque, wheel speeds and battery charge-acceptance limit.
Measurement and diagnostic strategy
Before clearing codes preserve engine speed/load, HV SOC/temperature, DC-bus voltage and motor-generator torque in one capture.
Using the safe service procedure cross-check 12 V supply and DC/DC output with independent measurement against scan data; do not open HV circuitry without proper isolation.
At comparable road load and SOC/temperature compare torque and energy flow before and after repair.
Exact pinouts, torque values, pressure thresholds or service limits are published only when explicitly verified by the applicable OEM service source.
