Zusammenfassung:	A test system is provided for primary and secondary brakes in a vehicle. The test system includes a two-position combination first valve having a first inlet coupled to a primary air supply, a second inlet coupled to a test air supply, and an outlet coupled to the primary brakes. The test system also includes a two-position combination second valve having a first inlet coupled to a secondary air supply, a second inlet coupled to the test air supply, and an outlet coupled to the secondary brakes. A system selector switch is provided for selectively applying current to one or both of the first and second valves responsive to a test signal input wherein each of the first and second valves directs fluid flow from one of the first and second inlets to the outlet.
