He said, “This compass, right here in the odometer screen.”

Then he asks, “Where is your compass?”

Me, “Hell, I didn’t know I had one!”

Long story short, all of the above items in my list of idiot lights that lit up, are wired through the N, S, E, W compass module. He used DLB to discover that. So in other words, it could be any number of sensors or modules in the truck. I never would have figured any of this out on my own. Sometimes the dealer is it.

I may need to check this out as well. My abs, tc, and warning triangle comes on and goes off. I changed the abs sensor that was showing a problem. Worked for a good while but then came back on
