Frequently Asked Questions

Q: What vehicles is this OBD2 scanner compatible with?

A: This OBD2 diagnostic scanner is compatible with all OBD2-compliant vehicles, which includes most petrol and diesel cars and light trucks manufactured from 1996 onwards in the US, and from 2001 onwards in Europe. Simply locate your vehicle's OBD2 port (usually found under the dashboard on the driver's side) and plug in the scanner.

Q: Do I need batteries or any external power source to use this scanner?

A: No batteries are required. This OBD2 code reader draws its power directly from your vehicle's OBD2 diagnostic port, so it's ready to use the moment you plug it in — no charging or battery replacement needed.

Q: Can this tool turn off the check engine light after I fix the problem?

A: Yes! This scanner includes a reset function that allows you to clear diagnostic trouble codes (DTCs) and turn off the check engine light once the underlying issue has been repaired. Note: if the fault is still present, the light will reappear after driving.

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

A: The I/M (Inspection/Maintenance) Readiness function checks whether your vehicle's emissions-related systems have completed their self-tests. This is especially useful before an emissions or smog inspection, helping you confirm your car is ready to pass — avoiding a failed test and re-inspection fees.
