If no repairs are needed, proceed to reset the check engine light.

On the OBD-II scanner, select the option to erase or clear codes.
Confirm the action and wait for the scanner to indicate that the codes have been cleared.
Disconnect the scanner from the OBD-II port.

Monitor the dashboard for any reoccurrence of the check engine light.
