Frequently Asked Questions

Q: Is this OBD2 scanner compatible with my vehicle?

A: This OBD2 diagnostic tool is compatible with all petrol and diesel cars, SUVs, light trucks, and heavy-duty vehicles manufactured from 1996 onwards that use a standard OBD-II / EOBD interface. This covers the vast majority of modern vehicles sold in the US, Europe, and beyond.

Q: Do I need batteries or a charger to use this diagnostic scanner?

A: No — this OBD2 scanner draws power directly from your vehicle's OBD-II diagnostic port. Simply plug it in and it's ready to use. No batteries, charging cables, or power adapters are needed.

Q: What can I do with Mode 6 and Mode 8 on this OBD2 tool?

A: Mode 6 gives you access to on-board monitoring test results for specific components and systems, helping you catch issues before they trigger a fault code. Mode 8 allows you to control on-board system tests, giving you deeper insight into component functionality — features typically found only on more expensive professional scan tools.

Q: Can I use this tool to pass an emissions (MOT/smog) test?

A: Yes! The built-in I/M Readiness check lets you verify whether all of your vehicle's emission monitors have completed their self-tests, so you can confirm your car is ready for an official emissions inspection before you go — avoiding a failed test and saving you time and money.
