Frequently Asked Questions

Q: Is the V320 OBD2 scanner compatible with my car?

A: The V320 OBD2 scanner is compatible with all OBD2-compliant vehicles, which includes virtually all cars, SUVs, and light trucks sold in the United States from 1996 onwards. If your vehicle was manufactured in 1996 or later, it is almost certainly OBD2 compliant. Simply locate the OBD2 port (typically found under the dashboard on the driver's side) and plug in the scanner.

Q: Do I need to install any software or batteries to use this scanner?

A: No. The V320 OBD2 scanner requires no batteries and no software installation. It draws power directly from your vehicle's OBD2 port and is ready to use the moment you plug it in. This makes it one of the most hassle-free diagnostic tools available.

Q: Can the V320 scanner turn off my check engine light?

A: Yes. Once you have diagnosed and resolved the issue causing a Diagnostic Trouble Code (DTC), the V320 can clear the code and turn off the check engine light. Keep in mind that if the underlying issue is not fixed, the light may reappear.

Q: What is an I/M Readiness check and why is it useful?

A: I/M Readiness (Inspection and Maintenance Readiness) checks whether your vehicle's onboard monitors have completed their self-tests. This is particularly useful before an emissions inspection, as it tells you in advance whether your car is likely to pass — saving you time and the cost of a failed test.
