What concrete information can you get from this page?
Verified application example: Europe · Duster III · Duster III hybrid/mild-hybrid evidence boundary · 1.2 L turbo mild-hybrid reference plus hybrid family · Variant-dependent
VERIFIED FACTModel / system fact
Third-generation Duster moved to the CMF-B platform and added mild-hybrid and full-hybrid powertrains to the family.
FAULT SEPARATIONWhen a symptom appears
For a hybrid warning verify 12 V and DC/DC supply first, then branch HV interlock/isolation, battery and inverter-motor DTC groups separately.
FIRST MEASUREMENTBefore replacing parts
Before clearing codes preserve engine speed/load, HV SOC/temperature, DC-bus voltage and motor-generator torque in one capture.

| Platform / generation | CMF-B |
| Powertrain / energy / driveline | C-SUV • MHEV/HEV/LPG; 4x2/4x4 |
| 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. |
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.
- 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.
Recorded application matrix and evidence boundary
| Record | Region | Period | Platform | Powertrain record | Evidence |
|---|---|---|---|---|---|
| VR-001289 | Other European manufacturers | 2024– | CMF-B | C-SUV • MHEV/HEV/LPG; 4x2/4x4 | 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?
- 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 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
- Third-generation Duster moved to the CMF-B platform and added mild-hybrid and full-hybrid powertrains to the family. [S1]
- Dacia’s current powertrain release publishes a 1.2 L three-cylinder turbo Miller-cycle 48 V mild-hybrid application. [S1] [S2]
- Hybrid and 4x4/LPG combinations create different energy and driveline architectures in the same body, so diagnosis must begin with variant verification. [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.
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.
