OBD2pro – diagnose and decode your car's error codes and malfunctions.

OBD2pro is a diagnostic scanner that communicates with your car's ECU and control units using the OBD2 protocol via Bluetooth or USB with ELM327 modules.

This app is built to identify malfunctions and clear error codes from your vehicle's electronic control units using the OBD2 standard.

It supports a wide range of cars, including both Russian and foreign models. The OBD2 protocol helps detect issues not only in the engine but also in other electronic systems—so the dreaded Check Engine light will no longer be a mystery.

Connect via Bluetooth or USB, then read and clear fault codes directly.

With OBD2pro, figuring out the cause of a Check Engine light is no longer a challenge.

Detected errors can be decoded using our built-in database, which includes comprehensive OBD code explanations—just enter the code and let the app tell you what it means.

As a bonus, the app also includes a Russian license plate lookup tool. See a number but don’t know the region? Enter the code or full plate, and get details instantly. Looking up license plate info is now hassle-free.
