ANCEL BD310 Bluetooth OBD2 Scanner — 2-in-1 Code Reader & App with Battery Test, Live Data (iPhone & Android)

The ANCEL BD310 is a compact 2-in-1 OBD2 scan tool that reads and clears engine codes on-device while offering Bluetooth app features for battery testing, trip analysis, and live performance data on iPhone and Android.

The ANCEL BD310 combines a dedicated wired code reader with a Bluetooth dongle that unlocks advanced diagnostics inside a free app. Designed for vehicle owners who want more than a simple code reader but less complexity (and cost) than professional tablets, this tool covers core OBDII functions, battery health checks, emissions readiness, and a customizable live-data HUD for safer monitoring while driving.

How will the BD310 help me understand a check engine light?

The BD310 reads standard OBDII trouble codes and presents easy-to-understand DTC descriptions so you can determine likely causes before visiting a mechanic. You can clear codes after repairs and confirm the fault didn’t return. The device also offers quick online lookup support for deeper research.

• Reads and clears MIL (check engine) codes on-device or via app
• Plain-English code explanations and built-in search support
• Freeze-frame data and live parameters to see when a code triggered
• Confirm fix by clearing codes and retesting

Can I check my battery and charging system with this scanner?

Yes — the BD310 monitors battery voltage in real time and includes a battery test mode in the app to assess starting and charging performance. Early detection of voltage irregularities helps reduce the chance of being stranded. You can log voltage trends and view alerts during trips.

• Realtime voltage readout and battery test routines
• Trip logs that record voltage and electrical events over time
• Detect charging problems and weak batteries before failure
• Visual alerts in the app for out-of-range voltage

Will this scanner help me prepare for emissions tests?

The BD310 supports I/M Readiness checks so you can verify emission monitor status at home and avoid failing an inspection unexpectedly. It reports the readiness status of monitors like O2 sensors and EVAP systems and indicates which systems need driving cycles or repairs. This saves time and potential retest fees.

• Reads I/M Readiness status for emissions monitors
• Identifies EVAP and O₂-sensor related faults
• Shows which monitors are “ready” or need more driving
• Avoids wasted trips to the testing station

How does the BD310 show live vehicle data while driving?

The BD310 offers a HUD mode and customizable dashboards inside the app so you can view speed, RPM, voltage and other live parameters on your phone or projected onto the windshield. Live data helps monitor performance during acceleration, braking, and longer trips without needing separate gauges. Customize layouts, save common parameter groups, and record sessions for later review.

• HUD display for speed, RPM, voltage and more while driving
• Customizable dashboards and parameter grouping
• Live data recording and trip analysis tools in the app
• Useful for monitoring performance and troubleshooting intermittent issues

Who is this for: The ANCEL BD310 is aimed at DIY drivers, weekend mechanics, and vehicle owners who want clear, actionable OBDII diagnostics without the cost or complexity of a professional scan tool. It’s particularly useful for those who run routine emissions checks, monitor battery health, or want live driving data and trip analysis on a phone. Compatible with most 1996 and later petrol and light-diesel cars, SUVs, and trucks, the BD310 is a practical upgrade over basic code readers while remaining simple enough for first-time users.
