Confirm the action when prompted.
Wait for the scanner to indicate that the codes have been successfully cleared.

If the check engine light remains on, use a socket set to disconnect the negative battery terminal.
Wait for approximately 15 minutes to allow the ECU to reset.
Reconnect the negative battery terminal and tighten securely.
