Frequently Asked Questions

Q: What vehicles is this OBD2 diagnostic scanner compatible with?

A: This OBD2 code scanner is compatible with most petrol and diesel cars, SUVs, and light trucks manufactured in 1996 or later that are equipped with a standard 16-pin OBD2 port. It supports all five OBD2 protocols including CAN, making it suitable for the vast majority of modern vehicles on the road.

Q: Can this scanner really turn off my check engine light?

A: Yes! Once you have read the Diagnostic Trouble Codes (DTCs) and addressed the underlying issue, you can use the erase function to clear the fault codes and turn off the check engine light. Note that if the underlying problem is not fixed, the light may return after the vehicle completes its drive cycle.

Q: Do I need to install any software or pay any subscription fees?

A: No. This is a completely standalone plug-and-play OBD2 scanner. Simply plug it into your car's OBD2 diagnostic port (usually located under the dashboard on the driver's side), and it powers on automatically — no apps, cables, software, or subscription fees required.

Q: What does the battery test feature do?

A: The battery test function measures your vehicle's battery voltage in real time, allowing you to monitor the health of your car battery. This helps you catch a weakening battery early before it leaves you stranded.
