Frequently Asked Questions

Q: What vehicles is the V100 OBD2 Scanner compatible with?

A: The V100 OBD2 diagnostic scanner is compatible with most petrol and diesel cars, SUVs, and light trucks manufactured from 1996 onwards that support the OBD2 standard. This covers the vast majority of vehicles sold in the US, UK, Europe, and Australia after that date.

Q: Do I need an app or phone to use the V100 scanner?

A: No — the V100 is a fully standalone wired device. It does not require Bluetooth, Wi-Fi, or a smartphone app. Just plug it directly into your car's OBD2 port and the tool displays results on its own screen.

Q: Can the V100 turn off my check engine light?

A: Yes. The V100 can read and clear diagnostic trouble codes (DTCs), which will turn off the check engine light once the underlying fault has been addressed. Note that the light may return if the issue is not properly repaired.

Q: Does the V100 require batteries?

A: No batteries are required. The V100 draws power directly from your vehicle's OBD2 port, so it's always ready to use without charging or replacing batteries.

Q: What is a car voltage tester and why do I need one?

A: A car voltage tester measures your car battery's current voltage to help you identify if the battery is weak, overcharging, or not being properly charged by the alternator. Catching these issues early can prevent unexpected breakdowns and costly replacements.
