What is an OBD2 port and where is it located?

The OBD-II (On-Board Diagnostics) port is a standardized connection point in your vehicle for reading diagnostic data. In most cars, it's located under the dashboard on the driver's side, near the steering column. All petrol and diesel cars sold in the US since 1996 have this port.

Do I need any special hardware?

You need an ELM327-compatible adapter (USB, Bluetooth, or Wi-Fi). These cost between $10–$30 and are widely available online. AIscanAuto works with any standard ELM327 adapter.

Can AIscanAuto clear my check engine light?

Is my data kept private?
