Beeping sound when starting/running International Terrastar w/Maxforce

Gonna look at it some more today. The vehicle hasn't moved since early December. Yes it's in park. Was wondering if it needed to have the exhast system regened but it doesn't give me any kind of warning message that it needs that. The beep doesn't go off?

 

Well guys thanks for your time and help, found the issue it was not related to anything with International chassis itself. Seems the last time I had the grandkids in the rv while it's been parked one of them must have pressed the autoleveling jacks button. Although they were not extended one of them was not quite all the way up in it's locked position. Hit the auto retract button and felt a slight movement on one of them. Then the beeping stopped. I guess I will chalk it up to the dummy proof warnings is a lot smarter than the dummy.
