2007 Chevy Tahoe LTZ 5.3 Service Suspension system/auto level system

[FINALTOUCHFRI]

My Service suspension system light came on and now I dont hear my auto leveling pump crank up anymore in the rear of the truck. Is there a way to test the rear pump before I purchase another one and find out it was a dumb relay????
