How do you test the tractor trailer protection valve?
Run the motor to air up the air system. Once this is done, cut off the motor. With the motor off, put the vehicle into gear. Then, you push in the tractor protection valve, which will release the spring brakes. You then pump the brake pedal (or the Johnson bar, if you prefer) repeatedly, and this will bleed out air pressure. When the air pressure gets low (below 60), the tractor protection valve should pop out automatically.

Why Low air pressure buzzer on freightliner wont go off?
Could be a short in the alarm system, could be that the valve which activates the alarm is stuck, could be because of moisture somewhere in the system... assuming that your air pressure is building up to normal levels, that is.
