Frequently Asked Questions

Q: What vehicles are compatible with this OBD2 diagnostic scanner kit?

A: The V519 OBD2 scanner is compatible with most 1996 and newer gasoline and diesel vehicles sold in the US, Europe, and Asia that support OBD2 or EOBD protocols. This includes most cars, SUVs, and light trucks. It does not support heavy-duty trucks or vehicles with proprietary non-OBD2 systems.

Q: Do I need to install any software or apps to use these tools?

A: No! Both the V519 scanner and BM310 battery tester are fully standalone plug-and-play devices. Simply plug the V519 into your vehicle's OBD2 port (usually under the dashboard) and the BM310 directly onto your battery terminals — no apps, software, or computers required.

Q: Can this scanner turn off my check engine light?

A: Yes. The V519 OBD2 scanner can read and erase diagnostic trouble codes (DTCs), which will turn off your check engine light after the underlying issue has been addressed. Note that if the underlying problem persists, the light may come back on.

Q: What does the I/M Readiness function do?

A: The I/M (Inspection and Maintenance) Readiness function checks whether your vehicle's emission-related systems have completed their self-tests and are ready for official emissions or smog testing. This helps you avoid a failed inspection and saves you time at the testing station.

Q: Does the BM310 work on all 12V car batteries?

A: The BM310 battery tester is designed for standard 12V automotive batteries, including flooded lead-acid, AGM, and gel-type batteries commonly found in cars, SUVs, and trucks. It can test battery condition and check alternator/charging system output.
