Does the A30M work on both iPhone and Android?

Yes. It pairs over Bluetooth with Android and iOS phones and tablets through the XTOOL app.

Can it do more than read engine codes?

Yes. It scans all major systems including ABS, SRS, transmission, body and TPMS, and supports bi-directional tests and service resets.

Do I need a subscription?

The core diagnostic and service functions work without one. Some brand-specific or advanced coding features may require software updates or licenses, so check coverage for your vehicle.

Which cars does it cover?

XTOOL lists support for 115 vehicle brands. Coverage of specific functions varies by make, model and year, so confirm your car before relying on a particular reset or coding job.

What comes in the box?

The scanner unit, a connection cable and quick-start documentation. A phone or tablet is required and not included.

Is it a substitute for a professional scan tool?

For DIY diagnostics, resets and active tests it covers a lot. For deep guided diagnostics and programming on late-model cars, a shop-grade tool still goes further.
