Beeping In Cockpit! (???)

My bus has started to beep sometimes after about half an hour or so of run time. Sounds like the same beeping as when the brake air pressure is waiting to go up, but it's doing it when air pressure is fine. I removed the air line to the door opening piston, since I closed that off. But I capped that line a while back, and this beeping started recently.


I attached a picture of the buzzer making the beeping sound. I followed it under the dash. If I push on it, the beeping gets "garbled".
Anyone have any idea what this could be, or how to figure it out?



Thanks,


Joe

Might want to get a list of the active codes in the ECU. If you don't have a scan tool you'll have to look up the procedure, but it involves pressing a button under the dash and counting the blinking lights on the dash.


I had the same problem with a buzzer. Codes were good, engine temp was good.. I pulled the buzzer Not saying that's what you should do, though!
In the end my issue could have actually been related to the engine temperature sensor. An aftermarket analog style one was added from the previous owner because the built-in dash temp sensor didn't work.

Thanks!


Anyone have a scan tool they recommend? It would be good to have one.
I have one of those for my FJC and Jeep. It's OBD2 and works with my iphone and ipad, but haven't seen one for diesel/Navistar T444e

OK
Sounds like a good idea.




What's Silverleaf and Bluefire?

I get the same beeping occasionally, despite my air pressure being fine. There are a few other threads here about it.

I was under the impression this was just a malfunctioning air pressure sensor. Are you guys saying this beeping could be indicating some other problem, like not related to air pressure? Is this beeper some kind of general purpose alarm that could mean all kinds of bad things?
