A few threads about that. It happened to me and I did the reset, but it came back again. Then I went under the seat and unplugged it and let it sit for about 15min. Reconnected everything and then did the reset again. The light has not returned yet. And I hope it never returns.
Everything is fine now.
Do a search and you will find the threads with pics in a few on how to unplug and do the reset after that.
I hope you get yours fixed.
