Ok. I got an 08 yukon denali xl. Last year I installed the monroe conversion kit and completely removed the air compressor, the level sensors and pulled the compressor fuse. I did not at the time (last year) install the supplied resistors. I had too many other things going on. Fast forward to last night. I installed the resistors only to start the vehicle and the service suspension message still to come on. Is it due to the fact I completely removed all the other components? From what I researched I'm thinking this may be the case.... any insight would be awesome. Also. I've read that some folks have had to put a resistor where the suspension compressor was to get the light to go out.

Well, it would be extremely helpful to use an advanced code reader on it to get the specific code that is triggering the message. That would help narrow it down.

You are not the only one. The supposed fix using resistors to shut down DTC and hide them could almost have enuf content to start its own forum.

Meanwhile, the great guys selling all the fix it, bypass your suspension kits are banking off your hard earned bucks vs fixing it once with guaranteed for life OEM struts.

Level sensors need to stay on

Oops. I yanked all 4 off and tossed them out... there probably isn't anything that I can do at this point I suppose. I wondered if that would possibly be of issue.

As far as codes. It was all 4 corner sensor faults, compressor and one other. Can't remember. I'll just live with it I suppose.

Why don’t the sellers of these bypass z95/z55 kits put that info in with the parts or kit? Just not cool to put all the omis on the poor buyer who’s already stretched on their budget?

It is a shame that you removed and disposed of the level sensors. You did not need to do that, and as @Doubeleive stated above, that is the source of your continuing issue with the warning lights.

Maybe, just maybe, if you disconnected the Suspension Control Module, the warning lights would go away. It is easy to do and worth a try.

Where is the suspension module? I removed it because I wanted to have nothing there that wasn't needed. Also I did read the directions and thought the resistors were the only thing needed. The other reason was I also really cleaned under the vehicle to get it nice.

it's wherever you left it? the garbage can and now probably the land fill?
or are you asking where it is located? if so it is under the frame by the spare tire.
if it is still there then you can just grab some level sensors from the junkyard and wire them back up.
