Hi, welcome to Just Answer. I’m Ron and I’ll be helping you
Before we get started though, Please understand that I don't know
your skill level or tools you have to assist us. Also understand that
I can't see, smell, hear, or touch the vehicle either, so patience is
appreciated. JA is a great Q/A site, but it does NOT replace a
repair shop.
My goal is to make you happy and get a great rating in return for
my time. Sometimes I have to give you bad news that I know you
didn’t want to hear, so please don’t shoot the messenger.

When that light comes on, a code is being set to help us diagnose why the light came on. We need to scan the computer system for codes and data that he scan tool will provide. It's impossible to tell what's wrong without getting the codes first.

Thanks, Ron
