It allows the driver to apply and release the truck and trailer parking brakes and to control the trailer air supply from a single location on the dash. The module is typically replaced when it develops air leaks, sticks, or fails to hold pressure – symptoms that can cause dragging brakes, an inability to release the parking brakes, or constant air loss from the dash area.
