Abstract
A method for testing functionality of a brake-system's select-high valve (SHV), including: comparing the pressure in a main-supply-circuit (MSC) with the pressure in a service-brake-circuit (SBC) and ascertaining that the SBC is being supplied with pressure from the other supply-circuit (OSC) if the pressure in the SBC is higher than the pressure in the MSC; increasing the pressure in the MSC above the pressure of the OSC; comparing the pressure in the MSC with the pressure in the SBC and ascertaining that the SBC is being supplied with pressure from the MSC when the pressure in the SBC at least approximately corresponds to the pressure in the MSC; and ascertaining that the SHV is functional if it has been ascertained that the SBC is being supplied with pressure from the OSC and that the SBC is being supplied with pressure from the MSC.
