Used-Car Technical Inspection: DTC, Chassis, Powertrain and ADAS
A pre-purchase framework combining full-module scan, live data, powertrain, chassis, SRS, ADAS and EV/HV checks.
Scan every control module, not only the engine
SRS, ABS, ADAS, body and transmission modules can reveal history that the engine ECU does not.
- Save the full-module DTC report.
- Check readiness/recently-cleared evidence.
- Compare VIN/module identity and mileage where the vehicle exposes it.
Mechanical and electronic evidence belong together
Cold start, compression, cooling, transmission adaptation, chassis condition and live data should support the same story.
- Observe a true cold start.
- Record powertrain data during a controlled road test.
- Relate tyre wear and suspension condition to alignment and structural evidence.
EV and ADAS add another inspection layer
Battery condition, isolation, charging behaviour and calibration history require checks beyond a conventional cosmetic inspection.
- Evaluate battery SOH and cell balance in vehicle context.
- Inspect sensor mounting, glass and body-repair history.
- Ask for calibration evidence and check the HV enclosure after collision repair.
Evidence supporting the same decision
Service note
This guide does not provide a fixed price or vehicle-independent replacement order. Exact procedures, torque, fluids, calibration and high-voltage values must be matched to verified service information for the exact vehicle application.
Sources & freshness
Exact technical values, prices and failure rates are not invented without verified vehicle/manufacturer evidence.
