Anyone had warning horn chirp just once

[Seasparrow]

It could have been something else but it sounded like it was my warning horn, it chirped once, less than 1/4 second. Just enough to have heard somthing. I have to take a trip saturday and don't want to try and pull codes with my cheap reader and upset the zero point reset gods.

I know my truck beeps at me when I take a corner or a bump too fast in 2WD with the VSD on. That is an audible electronic chirp. Not like a horn.

Do you think it could have been something like that?

I was in 2wd at 45mph just crusing along. it sounded more like a strong warning horn horn that just chirped once. It sounded more like an old warning horn,, if you ever flew an old aircraft it was that type. Also like an old 18 wheeler low air horn.

I was wondering what the brake low pressure warning horn might sound like?
