sounds like the ground there is a airline under the dash or side bay some where it well have a high or low pis switch make sure the plug is ok on it

giving your setup the ground going in well be open or closed you can test to see if its working right that is where the err well more be the part is only 12$ or so

i have a coachmen sportscoach and if your air system is the same for the most part

That sounds like a problem with the air system. Is it chiming all the time? Low air pressure chime possibly? Check with freightliner or big truck repair shop, could be dirty or wet (full of water) and stuck.

I'm thinking that the correct description would be the park brake air pressure sensor, but I'll check my air diagram to be sure.
I've got three chimes that all sound the same , does it only chime when you put the trans in gear?

My air system diagram, shows a Park Brake Warning Sensor Mod 882. I'll check my wiring diagrams and see if I can narrow down a location.

OK now I am confused, air brake diagram says Park Brake Warning Sensor and wiring diagrams say Park Brake Chime Switch

Diagrams show it within 2 feet of the ABS ECU that is by the differential on my chassis. Circuit wire numbers are different between the switch plug and the chime wires under the dash, back to the schematics to see where the wire #s change.

Wire # doesn't change, just need better glasses, schematics call the part , Park Brake Buzzer Switch , are they trying to confuse us, or what.
Call the Freightliner Help line ,1-800-FTL-HELP, have your serial # handy , they should be able to track the part to the nearest dealer.

I had a bad parking brake switch,(the electrical portion). 05 FTL chassis.Put a jumper on the two wires and see if the chime will stop.
Replaced the switch, about $ 15 then from FTL and all was ok.

Thank;s guy's , yes skip it chimes when tranny iis in gear. Freightliner said it is called the brake chime switch, witch is located in front of the drivers side rear axle. Tying to find one for sale. No dealer in my area has one,

Did the help line give you a part number , maybe you can get it from another source, if someone like NAPA can cross reference the number.
My air system diagram lists Wabco parts , so Freightliner isn't making there own , could be another chassis or truck company uses Wabco too.

Several years ago, I got one directly from Freightliner parts in Gaffney. Their phone number is 1 864 206-8584
