I sent in my module to Module Masters in Idaho.
They have a 5 year warranty. I was getting trifecta lights without
moving the car. I sent mine in without doing any other diagnosis.
The repair came back that it was indeed at fault.
I haven't finished my cooling system refresh to see if it's fixed.
I'm guessing the module was the culprit.
