LONAUTO Mini Bluetooth OBD2 Scanner LB02 for iOS & Android — Pocket Wireless Diagnostic, Live Data

The LONAUTO LB02 is a pocket-sized Bluetooth OBD2 scanner that plugs into your car’s diagnostic port to read and clear engine codes, show live data, and run basic vehicle diagnostics on iOS and Android devices.

If you want quick, on-the-spot insight into a check engine light or want to monitor engine performance without bulky equipment, the LB02 gives a simple wireless link between your vehicle and your phone or tablet. It uses an updated low-energy Bluetooth chip for a stable connection up to about 33 feet, and it’s designed for everyday drivers, DIYers, and mobile technicians who need fast, reliable OBD2 access for most passenger cars and light-duty trucks.

How does the LB02 help me diagnose a check engine light?

The LB02 reads standard OBD2 fault codes and displays them in plain text through the AutoOBDII app, so you can see what triggered the malfunction indicator lamp (MIL). You can also clear codes after repairs and view freeze-frame data to capture vehicle conditions at the moment a fault occurred.

• Reads and clears 35,000+ trouble codes across engine, body, and network systems
• Auto VIN scan to identify your vehicle model quickly
• Freeze-frame snapshots show conditions when a fault happened
• Simple code reading and clearing via the free AutoOBDII app

What live data and tests can I run with this wireless OBD2 adapter?

You can stream real-time vehicle parameters to your phone for instant feedback on engine performance. The LB02 supports live sensor data and data-graphing which helps you monitor RPM, speed, fuel trims, coolant temperature and other common PIDs supported by your vehicle.

• Real-time data streams and dashboard display of vehicle sensors
• Performance checks and graphing for trends over time
• Route analysis and data logging for later review
• Works with iOS (10+) and Android (6.0+) via the included app

Which vehicles are compatible and what limitations should I know?

LB02 works with OBD2/EOBD-compliant 12V petrol and light diesel vehicles (generally 1996+ in the U.S., 2001/2003+ in Europe depending on fuel type). It does not support heavy-duty 24V trucks, nor advanced service functions like ABS, SRS, EPB, TPMS, transmission resets or other manufacturer-specific reset services.

• Compatible with 12 communication protocols and standard OBD2/EOBD vehicles
• Not for 24V heavy-duty diesel commercial vehicles
• Does not provide ABS/SRS/TPMS or transmission reset services
• Ideal for typical passenger cars, small trucks, and DIY repairs

How safe and convenient is leaving the LB02 plugged in?

Designed for low power draw and safety protections, the LB02 supports auto-sleep along with over-voltage, over-current and over-temperature safeguards to prevent battery drain and protect the vehicle’s electrical system. If no Bluetooth connection is detected, it drops into a very low-power sleep mode automatically.

• Auto sleep after 30 minutes with current as low as 3mA
• Operating current 28–32mA during active use
• Built-in protections against over-voltage, over-current, and overheating
• Compact pocket-sized design that won’t protrude from the port

Who is this for: The LONAUTO LB02 is made for car owners, travelers, DIY mechanics, and small repair shops that need a compact, budget-friendly Bluetooth OBD2 solution for reading engine codes, monitoring live data, and clearing standard faults. It’s a practical tool if you own OBD2-compliant passenger vehicles or light trucks and want immediate diagnostic information on your phone without professional-grade reset services.
