You are in the GMC Yukon
What is this discussion about?
GMC Yukon Denali, GMC Yukon XL, SUV
#139 of 247 Re: 2010 Denali XL [ukondoit]
Sep 29, 2010 (6:00 am)
Cadillac Escalade ESV factory equipped with 22" wheel/tire combo, which has less sidewall (reduced road shock absorption) than what is factory installed on the Denali, and the NEW Escalade (4 miles on the odo) rode butter smooth.
Our old 2007 Yukon XL had the same exact tires w/20" rims (factory combo).
There's something definitely wrong with the Denali, but GMC hasn't done anything yet to attempt to find the problem - all the mechanics will say is "There's no fault code so our hands are tied, there's nothing wrong, suspension operates as designed."
First mechanic blew smoke up 'you know where' with the following statements: 1) GMC builds the Denali's more like trucks now; 2) Give the vehicle 20,000 miles to break in the suspension; and 3) The vehicle will ride better fully loaded.
My responses: To statement 1 - If I wanted the ride of a truck, I would have bought one. Besides, why then all the seats? To statement 2 - Funny, our 2007 Yukon XL, same body style, rode perfect from day 1. To statement 3 - It's only my wife, myself and our 2 dogs. When, if ever, will I get the vehicle fully loaded? Shouldn't the suspension operate correctly regardless of the load? I towed my bass boat around and the ride got worse.
No call yesterday from GMC Tech Dept. Maybe today?

mag44...thanks for all your posts thus far!
"Service Ride Control" (msg on dash)
I've skipped all over and need to find out what sequence I should be troubleshooting this problem before I just shoot myself!
I've replaced the compressor (w/Arnott)
Bench tested compressor (runs fine)
Replaced blown 40A fuse (Stud 1)
Checked IGN3 10A & RTD 10A (both OK)
Tested Relay by jumping 85w/86, 87 to ground & 30 to 12V (No clicky?)
Jumped 87w/30 on Relay & heard compressor run
Have NOT done anything yet with Blue/White wires on solenoid.
Thanks in advance!!

It sounds like your relay is bad, if you run 12 V to 30 and a ground to 87, then jumper 85 and 86 and no click then it's the relay. When you jumper 87 directly to 30 you are just hot wiring directly to the compressor.
The other test you can do is jumper the blue & white wire on the truck side of the connector on the compressor when is't hooked up to make sure the exhaust solenoid is working.
But from what you said I would replace the relay.
The last two things would be checking the wheel sensors and the new Arnott sensors if the relay does not solve your problems.
Please let me know how it goes.

Do you know who is knowledgable enough to repair autoride? Dealer says all is working correctly on my 2003 Dinali, but rides like a go cart on gravel.

If all the components seem to be working but still riding rough then the local dealer should be able to help or a local shop. Sorry I have no idea beyond what you already tried.
It sounds like you have no fault messages and you can hear the compressor come on like it should?

Yes, things are working well, except the ride. Thanks for your reply. I will let you know what I come up with in the future. I will be changing the shocks soon. I do have 150,000 miles on the rig.

You were spot on. My 04 Denali XL's compressor quit working a few weeks ago and I received the "Service Suspension" error on my information center. I checked fuses, power to the pump, etc. Same thing as everyone else. My neighbor was helping me test the system- so we pulled the compressor out and bench tested it. Compressor kicked in when we gave it juice- which baffled my neighbor. I said, "Hey- let's pull this top cover off where the blue and white wires go in. There was a guy on a forum talking about a wire broken off at the terminal." You were right. We tested the coil and we weren't getting any reading. We found the broken wire, soldered it back, tested and we were in business. Re-installed the pump, turned the rig on, and the sweet sound of the compressor was on again. The message was gone as well.
Thank you so much for saving me at least $180 on this fix!
If you are ever in Bismarck, ND I will buy you a beer!!
Thanks again, Tim.

Hey Tim, Your welcome...I'm glad that worked out for you. I will put you in the book for the next time I drink my way across the country!! Thanks.
#147 of 247 2004 Yukon XL "Service Stability" message
Oct 24, 2010 (6:15 pm)
I was driving my 2004 Yukon XL and the "Service Stability" message came on AND STAYS ON. Also accompanying the error message are two idiot lights ABS (Brakes) and T/C (Traction Control). I checked brake fluid levels and it is just below the max fill line on the reservoir. Also have heard a dragging sound in the area of the right front wheel but they aren’t hot when I touch the hub area. The sound really is evident when making left turns regardless wither they are sharp turns or not. I hooked up the Scantool® analyzer and it tells me no error codes were found and everything tests good. What does this error message mean and where do I start? Please, any advice would be appreciated. Thank you in advance.

Have you had your shocks checked? You may find that one if not both may be bad. My 03 Denali did the same thing. When I had the vehicle raised we were surprised to find that the passenger shock had failed and was lowered; while the drivers side had failed but was still supporting the weight of the vehicle.
The compressor is usually quiet and usually turns on a few seconds after the vehicle is started. The compressor may need new rubber bushings as well to lessen the vibration which in turn lessen the noise of the compressor. Let me know what oyur find out. I have other leads for you as well.
