Auto Pro Data

AutoProData turns your phone into an OBD-II diagnostic tool. Plug a Bluetooth Low Energy (BLE) OBD-II adapter into your car, connect in seconds, and see what your engine is doing in real time. WHAT YOU CAN DO • Live dashboard – Watch engine data on clear, easy-to-read gauges: engine RPM, vehicle speed, coolant temperature, engine load, throttle position and more, depending on what your vehicle supports. • Monitoring – Choose the sensors you care about and follow them while the engine runs. • Diagnostics – Read diagnostic trouble codes (DTCs) stored by your vehicle. For each code, see a description, the affected system, severity, urgency, possible causes and common symptoms. • Research a code – Search any trouble code on Google, YouTube, Reddit's MechanicAdvice community or OBD-Codes.com with one tap. • Automatic connection – AutoProData finds supported adapters nearby and connects automatically, or lets you pick one from a list. • Light and dark mode – Comfortable to read in the garage or at night. • Guided tour – A short in-app tour shows you how to get started, available in English, Spanish and Portuguese. WHAT YOU NEED • A Bluetooth Low Energy (BLE) OBD-II adapter compatible with ELM327 commands. Classic Bluetooth-only adapters are not supported. • A vehicle with an OBD-II port. Most gasoline cars and light trucks sold in the US since 1996, and in the EU since 2001 (gasoline) and 2004 (diesel), have one. • An Android phone with Bluetooth LE. HOW TO START 1. Plug the adapter into your vehicle's OBD-II port, usually under the dashboard near the steering wheel. 2. Turn the ignition on. 3. Open AutoProData and tap "Tap to Connect". The data shown depends on your vehicle's make, model and year and on your adapter. AutoProData provides general information and does not replace an inspection by a qualified mechanic. Do not use the app while driving.
