The system is pretty simple. You have a control module that energizes the relay when the height sensor says your truck is too low. The relay turns on the compressor which fills the airbags. The is a valve on the airbags which I think acts as a one way check valve. That's about it. You can just 12Vdc directly to the compressor to see if it turns on. You'll need a schematic to know the inputs and outputs of the relay. Since it's solid state it won't make a clicking sound like an electro-mechanical one does. You'll have to put 12Vdc on the input and use a DVOM to look for continuity on the output side.
