Avto Test PRO

Why does your car display a warning light you have never seen before?

Avto Test PRO turns your Android phone into a diagnostic tool that reads and clears trouble codes directly from your vehicle’s ECU. No guesswork, no expensive shop visits — just plug in an OBD2 adapter and see exactly what your car is trying to tell you. Whether you are a weekend mechanic or a professional driver, this app gives you the raw data you need to make informed repair decisions.

Core diagnostic capabilities

• Full OBD2 code reading – Supports generic (P0, P2, P3, U0) and manufacturer-specific codes for most cars sold after 2008.
• Live sensor data stream – Monitor RPM, coolant temperature, oxygen sensor voltage, fuel trim, and up to 30 other parameters in real time.
• Clear check engine light – Reset DTCs and turn off the MIL after completing a repair, with a clear confirmation log.
• Freeze frame analysis – View the exact sensor readings recorded when a fault code was triggered, helping you diagnose intermittent problems.
• Graph view mode – Plot up to four sensor values simultaneously on a scrollable timeline to spot patterns during test drives.
• Vehicle information lookup – Retrieve VIN, calibration IDs, and supported OBD2 protocols directly from the ECU.
• Code definition database – Built-in glossary translates cryptic codes into plain English descriptions with probable causes and repair tips.
• Trip computer – Calculate fuel economy, distance, and average speed using data from the vehicle’s sensors.

Key advantages for daily use

• Works offline – All diagnostic functions operate without internet access. No data plan required during scanning.
• Low battery impact – Uses Bluetooth LE for adapter communication, reducing phone power drain compared to WiFi-based tools.
• Multiple adapter support – Compatible with ELM327, OBDLink, and generic Bluetooth OBD2 adapters (recommended v1.5 or higher).
• One-tap screenshot export – Save fault code reports as PNG images for sharing with mechanics or insurance adjusters.
