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.

Monitors are very stubborn sometimes and can be held back from running due to a different problem that you're not even aware of. To find out everything, a scan tool needs to be used in MODE 6. But first, see attachment for how to run monitors.

Thanks Ron
