Can I clear a check engine light with an OBD2 scanner?

Yes. All OBD2 scanners can clear diagnostic codes and turn off the check engine light. However, if the underlying problem is not fixed, the light will return.

Do OBD2 scanners work with electric vehicles?

Most EVs have an OBD2 port but use proprietary diagnostic protocols. Standard OBD2 scanners can read basic codes. For full EV diagnostics, use manufacturer-specific tools.
