I've got a 2001 or 2004, can't exactly remember, International 3800 DT466e. It was working well, let it sit for 3 months, and I come back to the warn engine light being on on startup. If I let it sit and warm up, the light disappears and it drives.
When I hold down the engine diagnostics button, it blinks for almost 2 minutes shown here.
What am I looking at here?
