its actually on your car computer engine so it won't go off even if take the battery off so for your safety it means you need to take it to your local Honda dealer for maintenance may be there is something wrong with your car. so don't try ignore this it will come back to you later so better get it maintain asap or if you don't want to spend money on it try taking it to your nearest Auto zone. they can ran it through their computer and may be they can tell you whats the problem is even take the light off and they won't charge you. its free. good luck.
