A: This scanner is compatible with approximately 98% of vehicles with a 16-pin OBD2 port manufactured in 1996 or later (US), 2000 or later (EU), and most Asian vehicles. Verify your vehicle has a standard 16-pin OBD2 port before purchasing.

Q: Can I use this scanner to turn off my check engine light?
