Q: Can the V420 scanner turn off the check engine light?

A: Yes! The V420 OBD2 scanner includes a reset function that allows you to clear Diagnostic Trouble Codes (DTCs) and turn off the check engine light after you've addressed the underlying issue.

Q: What is I/M Readiness and why does it matter?
