It has been in the teens here for a couple weeks and twice now on startup I’m getting a real high pitched like warning noise. It’s inside the cab, definitely an electronic noise and ZERO warning lights or any indication there’s a problem.

I’ve done a Quick Diagnostic and the In Depth one and no codes.

It sounds like when your low fuel light comes on but no light and I have plenty of gas. Last about as long as when the low fuel light comes on too.

Doesn’t seem to be acting up though.
