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.

How does the low air pressure warning buzzer work on 1996 peterbilt 379?
The low air pressure warning buzzer on a 1996 Peterbilt 379 activates when the air pressure in the system drops below a predetermined threshold, typically around 60 psi. This is monitored by pressure sensors connected to the air brake system. When the pressure falls below this level, the sensor sends a signal to the warning system, which triggers the buzzer to alert the driver of the potentially dangerous condition, prompting them to take corrective action. Regular maintenance of the air system is essential to ensure the proper functioning of the warning system.
