Hmm. No nobody local. I've ordered a code reader. There's about 10 different DTC codes the suspension control computer will send and I'm expecting that there's some in there related to voltage or something. None of them will actually cause the CHK SUSP light either from what I've read. Unfortunately most of the diagnostic procedures at this point involve the Consult III scanner == dealer $$$It sounds as if the height sensor is not sending the signal on time or the computer not receiving the signal. I only had to mess with my compressor and strut, as I had them both leaking air. Do you know someone local that may lend you their height sensor for you to test? I would imagine that has to be cheaper than the computer or relay that received the message under the hood.I'm down to maybe the height sensor or computer needing replacement. Maybe the potentiometer inside the switch starts sending the wrong voltage signal back to the computer? It's funny because I'll cycle it, get it to the right height manually by releasing all air that was built up. Shut off the truck and bolt it back to stock. Turn the truck on and 20sec later it jacks it up to 38", 2" too high. It's gone higher before too
