Warning buzzer question

I have a question for you all. My 99 F-250 Superduty has the 7.3L auto in it. It has a chip in it that was installed by someone else. I have no idea if that contributes to this, but after starting it, it will buzz with 5 bursts. Each one has about a second between it. After the 5 bursts, it will pause for 5 seconds and then begin again. It will do this for 5 times and then stop. After that, the truck will not buzz again for exactly 30 minutes, and then the cycle will begin again. It lasts for a minute or two all together. Then it will be quiet for another 30 minutes and do it again, etc. It will NOT do it with the key off or anything like that. It only happens after starting and then 30 minute cycles thereafter. There are no lights on on the dash. Any idea of what to check? Thanks!

It has to do with a blown light out on the dash.

I had noticed when I bought the truck that there is no airbag light that comes on but wasn't sure if it had one or not. Makes sense though. Will check it out. Thanks.
