System map

• Evaluate fuel supply, rail target/actual pressure, injector balance, charge-air path and EGR/DPF/SCR in the same event capture.
• A boost fault is not just the turbo; separate leaks, wastegate/VGT, vacuum/electric control, MAF/MAP and exhaust backpressure.
• HV battery, BMS, isolation, inverter, OBC/DC-DC, 12 V and thermal management are separate evidence chains.
• Do not interpret DPF soot/ash, differential pressure, EGT, NOx, SCR dosing and EGR in isolation.

Measurement and verification sequence

1. Capture low-pressure supply, rail target/actual, MAF/MAP, boost and exhaust temperature during crank and load.
2. During READY/charging, monitor pack temperatures, cell delta, isolation, 12 V and charging-power curve together.
3. Compare pressure, temperature, soot load and NOx conversion before/after regeneration in the same drive.

Misdiagnosis traps

• Without leak and actuator-command verification, a healthy turbo can be replaced unnecessarily.
• Displayed range or one SoH value alone does not prove battery health.

Variant-specific system split

• Fuel path is separated into low-side supply → high-pressure pump → rail → injectors; air path into MAF/MAP → turbo control → intake manifold.
• On turbo-petrol architecture, load calculation, boost target/actual, lambda/fuel trim, ignition and knock control are compared in the same event window.
• EGR, DPF/FAP, EGT, NOx and SCR/DEF aftertreatment interact with engine torque request; derate can be a secondary result.
• In an EV, HV battery/BMS, contactor-HVIL/isolation, inverter-motor, OBC/DC-DC, 12 V and cooling circuits are separate evidence branches.
• On torque-converter automatics, TCC slip, input/output speeds, commanded/actual ratio, fluid temperature and line-pressure control are tracked separately.

Freeze frame / live data

• 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.
• Aftertreatment: DPF differential pressure, soot/ash calculations, EGT chain, NOx in/out and SCR/DEF dosing enable.
• Live data: calculated load, MAP/boost target-actual, throttle angle, lambda/O2, STFT/LTFT, ignition advance and knock retard.
• 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

• 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.
• On lean/misfire/boost complaints, align fuel trim, lambda, ignition retard and boost deviation on one time base to separate air leak, fuel-delivery and ignition causes.
• For DPF/SCR faults, separate sensor result from real loading: differential pressure, EGT chain, soot/ash calculation and NOx conversion must be physically consistent.
• 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.
• On torque-converter automatics, separate TCC slip from actual gear-ratio error; temperature-dependent line-pressure/solenoid behavior can mimic mechanical clutch faults.

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.
