Frequently Asked Questions
Do OBD2 scanners work on all cars?
OBD2 scanners work on all vehicles sold in the US since 1996, in the EU since 2001 (gasoline) and 2004 (diesel), and in Asia since 2008. Some features (ABS, SRS) may require vehicle-specific protocols.
Can an OBD2 scanner clear the check engine light?

Is BlueDriver worth the price?
BlueDriver Pro ($109.99) is widely considered the best value Bluetooth scanner. Its 8000+ issue database, repair reports, and no-subscription model make it a top choice for DIY mechanics.
