Hi. Did you get this sorted? I had the same problem with 2013, on original battery. Just had it changed at local kwik fit, as nowhere else open and now the warning won't go off? Do you or did anyone tell you how to reset this yourself - or did you have to get diagnostic help from a garage?
This is a known problem with Honda but no factory recall as yet. Quick fix disconnect the negative on the battery leave for five minutes reconnect and the car resets itself. May have to do a few times.
