Looking for the section on trouble shooting the leveling suspension on a GMC 2004 Yukon Denali. Do you mind sharing that section of your manual if you have it?
Thanks,
Hugh

Eh, I can`t get it to work OK in my scanner; I have the huge paper manual and it`s not gonna work
What does the problem appear to be?
I probably won`t be of much help here as I`ll be offline until tomorrow and, well...I can`t get the pages digitalized.
I`d suggest going over to gm-trucks.com and asking for some assistance there.

No signs of weirdness like something knocked out of whack, right?
So, I think you need to hook up a scan tool and see if the problem is related to:
-Suspension Control Module
-Compressor Leveling Module (Air Pressure Sensor and/or Exhaust Selenoid)
-Compressor Motor Relay
-Compressor Motor
As I read the FSM, you need the scan tool to start narrowing things down and there are about a dozen pages of diagnostic procedures.
You`re probably gonna get better advice at that GM forum, I simply don`t know what I`m talking about here.
Thanks for your info so far, I still need to find somebody with the manual, then I can take it from there.Originally Posted by Accumulator

Do you have the appropriate scan tool?

Someone will have a link to the manual or scanned pages. Just make a request on a GM forum and you will get quick help.

It just might be a necessity once you get past the obvious mechanical stuff that you can often just eyeball.
But as Brad B. said, somebody on one of the GM forums will probably be able to help you out. I bet it`s one of those things that`s almost always [this-or-that] and somebody will probably help you narrow it down in no time.
