1) Capture Context
- Record codes (DTCs), freeze frame, and VIN.
- Note symptoms: misfire, rough idle, poor fuel economy, etc.
- Check recent work: battery, intake, exhaust, sensors.
2) Group and Interpret Codes
OBD2 Assistant automatically clusters codes and highlights probable root causes with confidence estimates.
3) Validate with Live Data
- Corroborate with STFT/LTFT, O2/AFR, MAF/MAP, coolant temp.
- Use graph overlays to spot drift vs. step-change anomalies.
- Apply built-in workflows for common P0xxx patterns.
4) Confirm the Fix
Clear codes, perform drive cycle, and re-check. Export a professional report for the customer record.
