Frequently Asked Questions

Q: What vehicles are compatible with the V315 OBD2 car scanner?

A: The V315 OBD2 scanner is compatible with all OBD-II compliant vehicles, which includes most cars, SUVs, and light trucks manufactured and sold in the United States after January 1, 1996. Simply locate the OBD-II port (usually under the dashboard on the driver's side), plug in the scanner, and you're ready to go.

Q: Do I need a battery or any special installation to use this scanner?

A: No batteries or installation are required. The V315 OBD2 code reader draws its power directly from the vehicle's OBD-II diagnostic port, making it a true plug-and-play device. Just connect it to your car's port and the scanner powers on automatically.

Q: Can this scanner turn off the check engine light?

A: Yes! The V315 can both read and clear Diagnostic Trouble Codes (DTCs), which will turn off the check engine light once the underlying issue has been addressed or the code has been cleared. Note that if the underlying problem persists, the light may return.

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

A: An I/M (Inspection and Maintenance) Readiness Test checks whether your vehicle's onboard diagnostic monitors have completed their self-tests, which is required to pass a state emissions inspection. The V315 lets you run this test at home so you can identify and fix any issues before your official emissions check, saving you time and a potential failed inspection fee.
