This sounds very much like the problem I had on a 2000 HR Endeavor on a Freightliner chassis. Warning sound would come on at random times. Stopping the coach followed by cycling the parking brake switch would silence the alarm for a while, then it would come back.
The cure was an air pressure sensor located on an air line, driver side, along frame rail just in front of rear axle. If I remember correctly, it threads into a manifold, and has two wires.
For diagnosis help, call the Freightliner help desk (1 800 ftl-help). It's free and they are good. Be sure to have the last 6 digits of your vin number available as they will ask for that to find the info on your chassis.
I did a little research that may help. Look at this thread linked below from the Freightliner chassis forum on IRV2. Post # 15 will have a picture of the air pressure sensor as it is mounted on the frame rail.
