Verified application example: Cited OEM source scope · Source-defined generation / market · BMW iX · a dedicated battery-electric SAV using BMW eDrive, high-voltage battery and central vehicle electronics · OEM-defined for cited variant; resolve exact configuration by VIN/market
VERIFIED FACTModel / system fact
BMW iX is documented by BMW in the cited official material as a dedicated battery-electric SAV using BMW eDrive, high-voltage battery and central vehicle electronics.
FAULT SEPARATIONWhen a symptom appears
Preserve freeze-frame and HV/12 V supply data before clearing codes; low 12 V voltage can create secondary HV and communication faults.
FIRST MEASUREMENTBefore replacing parts
Capture 12 V supply/DC-DC output, HV SOC/temperature, DC-bus voltage and drive-unit torque/temperature together before clearing faults.

What is the first fault-separation step?
Preserve freeze-frame and HV/12 V supply data before clearing codes; low 12 V voltage can create secondary HV and communication faults.
What should be measured before replacing parts?
Capture 12 V supply/DC-DC output, HV SOC/temperature, DC-bus voltage and drive-unit torque/temperature together before clearing faults.
Exact oil/fluid capacities, torque, pressure or pin values are shown only when verified in an OEM source for the matching model year, engine and market.

Where should diagnosis start?
Check charging, HV isolation, 12 V supply, thermal management and software state as separate evidence chains.
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?
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.
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.
6) After repair, recreate the same load/temperature and verify DTC state, live-data deviation and user symptom together.
Root-cause discrimination matrix
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.
OEM EVIDENCE DOSSIER
Verified technical facts and application boundary
BMW iX is documented by BMW in the cited official material as a dedicated battery-electric SAV using BMW eDrive, high-voltage battery and central vehicle electronics.[S1]
The cited OEM scope identifies dedicated EV architecture with HV battery, eDrive units, charging, thermal management and integrated vehicle control; generation, market and software differences must stay inside that documented scope.[S1]
BMW Technical Information System is the primary service-information authority for model-specific repair procedures, wiring/diagnostic information and calibration identification; uncited fitment is not extrapolated.[S2]
Verified application matches
The matches below are published only within the stated market, model-year and evidence scope. Fitment is not extrapolated to uncited variants.

Engine: a dedicated battery-electric SAV using BMW eDrive, high-voltage battery and central vehicle electronics
Transmission: OEM-defined for cited variant; resolve exact configuration by VIN/market
Evidence scope: OEM product/press + technical service information
System architecture and component relationships
Treat BMW iX as a high-voltage system: HV battery/BMS, contactors and interlock, inverter/drive unit, DC/DC and 12 V supply are separate diagnostic layers.
Time-align battery SOC/temperature, DC-bus voltage, commanded/actual drive torque, inverter temperature and 12 V/DC-DC data before condemning a component.
Charging complaints must be split between EVSE/charge inlet, onboard charging/DC fast-charge communication, battery thermal conditioning and BMS limits.
DTC / SPN-FMI / symptom discrimination map
Preserve freeze-frame and HV/12 V supply data before clearing codes; low 12 V voltage can create secondary HV and communication faults.
For no-drive or reduced-power, branch HV isolation/interlock, BMS limits, inverter/drive-unit feedback and thermal derate separately.
For charging faults compare commanded charge state, connector/EVSE status, battery temperature/SOC and charger/BMS DTC groups before replacing hardware.
Measurement and diagnostic strategy
Capture 12 V supply/DC-DC output, HV SOC/temperature, DC-bus voltage and drive-unit torque/temperature together before clearing faults.
Follow the OEM high-voltage isolation procedure before any direct HV measurement; use scan data and approved test points rather than invented pack-cell or insulation thresholds.
Repeat the complaint at comparable SOC, battery temperature and road load and compare command-versus-actual energy/torque 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.
