UMEIJA OBD2 Scanner V011 Bluetooth 5.4 — Car Diagnostic Tool for iOS & Android with Live Data

The UMEIJA V011 OBD2 Scanner is a Bluetooth 5.4 diagnostic adapter that reads and clears engine codes, streams live sensor data, and generates diagnostic reports on iOS and Android phones.

Install this compact plug-and-play adapter into your vehicle’s OBD2 port to access a wide range of fault-finding and performance checks from your smartphone. The V011 pairs with a free dedicated app to display live data charts, DTC descriptions, VIN retrieval, and readiness monitors. It supports most cars made since 1996 and uses upgraded Bluetooth 5.4 for quicker, more stable connections.

How will the V011 identify and explain check engine lights?

The scanner reads diagnostic trouble codes (DTCs) and shows human-readable descriptions in the app so you can understand likely causes. It also lets you clear codes once underlying issues are resolved, helping verify repairs.

• Fast DTC retrieval and printable diagnostic reports
• Clear CEL/MIL after repair (cannot permanently hide unresolved faults)
• Freeze frame and stored sensor data to reproduce fault conditions

What live data and performance tests can I run with this tool?

The V011 streams live vehicle data and visualizes parameters like engine RPM, coolant temperature, and voltage so you can monitor systems in real time. The app supports multiple onboard monitoring tests and saves data for comparison.

• Real-time sensor graphs and easy-to-read charts
• Data streaming, freeze frame, and logged sensor values
• VIN retrieval and readiness monitors for emissions checks

Which cars and phones are compatible with the V011 OBD2 scanner?

The V011 is designed to work with over 96% of passenger cars from 1996 onward and supports nine OBD protocols used across major brands. It works with iOS and Android via the dedicated app; follow pairing instructions for best results.

How do I connect and use the Bluetooth 5.4 adapter safely?

Plug the V011 into the vehicle OBD2 port, start the car (or turn ignition on) and enable Bluetooth on your phone. Open the dedicated OBD Home app — Apple devices typically auto-connect without manually pairing in Settings.
