A: This OBD2 diagnostic scanner is compatible with all petrol and diesel vehicles manufactured since 1996 that comply with the OBD2 standard. This includes most cars, trucks, SUVs, and minivans sold in the US, Canada, Europe, and other regions. Simply locate your vehicle's 16-pin OBD2 port (usually under the dashboard on the driver's side) and plug in the scanner.

Q: Do I need a battery or charging cable to use this scanner?

A: No external battery or charging cable is needed. This OBD2 scanner is powered directly by your vehicle's OBD2 diagnostic port, so it's always ready to use whenever you need it — just plug it in and start scanning.

Q: Can this tool reset or turn off the check engine light?

A: Yes! Once you've read the diagnostic trouble codes (DTCs) and addressed the underlying issue, you can use the erase function on this scanner to clear the fault codes and turn off the check engine light. Note: if the underlying problem is not fixed, the light may reappear after a short drive.

Q: What is the I/M Readiness function?

A: The I/M (Inspection & Maintenance) Readiness function checks the status of your vehicle's emission-related systems and sensors. It tells you whether your car is ready to pass an emissions or smog test, helping you avoid a failed inspection and potential fines.
