Sleeper air bags

[marek4792]

I would test the circuit by simply getting an air pressure gauge with a push connect fitting on it, and plumb it to the leveling valve circuit to see if it achieves and holds full pressure. If pressure is good then T it off to the airbag circuit after the leveling valve to see which bag is bringing it down. Not all airbag leaks are audible or as detectible by the soapy water test. Try this to narrow it down atleast.
