Frequently Asked Questions

Q: Will this OBD2 scanner work with my car?

A: This scanner is compatible with all vehicles that support the standard OBDII protocol — which includes virtually all gasoline-powered cars and light trucks sold in the US from 1996 onward, EU gasoline vehicles from 2001+, and EU diesel vehicles from 2003+. If your car has an OBD2 port (usually located under the dashboard on the driver's side), this tool will work with it.

Q: Can this scanner permanently clear my check engine light?

A: Yes — this OBD2 code reader can clear Diagnostic Trouble Codes (DTCs) and turn off your check engine light (CEL). However, if the underlying issue is not repaired, the light may come back on. It's best to address the root cause of the fault code for a permanent fix.

Q: Do I need to install any software or connect to an app?

A: No. This is a standalone wired scanner that works without any app, software, or Bluetooth connection. Simply plug it into your car's OBD2 port and start diagnosing immediately.

Q: What is I/M Readiness and why does it matter?

A: I/M Readiness (Inspection & Maintenance Readiness) tells you whether your vehicle's onboard diagnostic systems have completed their self-tests and are ready for an emissions inspection. This feature helps you avoid failing your smog or emissions test by letting you check your car's readiness status in advance.
