SOURCE: 2004 yukon xl denali self-leveling rear air shocks

There's a lever that connects the driver-side rear shock to the Automatic Level Control module (the air compressor and the ride-height sensor). Disconnect the lever from the shock and rotate it up and hold it. The compressor should kick in when you hold in place after a few seconds. If it doesn't kick in, make sure your fuses and relays are good. Otherwise, you may have a failed ALC module/burned out air compressor (from the shocks being shot). After you replace the shocks (and after you recouped from the heart attack you had when you shelled out $500+ for each shock), replace the ALC module/compressor (it's all one unit), and test it - it should kick on when you rotate the lever up again.

Figure about $350 for the ALC module from your dealer, and make sure the part numbers match! Your truck came with an upgraded ALC module from the 2001-2004 module, which were prone to water damage.

Good luck!

leaking suspension air bags is the most common cause, but the system can be tested for trouble codes, I suggest u do so, only the dealer can do this, but guessing about what the problem is can get very expensive very fast.

SOURCE: 02 yukon denali security light stays on will not

Several GM products, including the Chevrolet Impala and Malibu, the Oldsmobile Alero, the Pontiac Grand Prix, and Saturn Ion, have issues with the Security light coming on. This is many times an indication of a failing Body Control Module (BCM). Initially, the Security light will come on then go off, progressing to a constant on light, before the car will refuse to start. Other symptoms may include erratic action of electronics, a clicking sound coming from the glove box, and the air conditioning failing to blow cold air. I recommend a shop that specializes in the electronic systems of vehicles to diagnosis and make the necessary repairs. They should keep the car until they replicate the symptoms described. A new BCM from GM should cost about $230; plan on another $200 for them to diagnose the problem, replace the unit, and program the new unit. The dealers quote between $700 and $1,100 for the same repair. My experience and the experiences I have read on the internet, indicate the new BCM should last only about a year.

SOURCE: what does service ride control light on a Yukon XL

It means you should take it to the dealership so they can check the pressure in the system and reset the sensor.

Where is the air compressor for the ride control on 06 gmc denail


Ride control compressors burn up because of leaking air line or shocks. Replacing compressor won't last long if you have a leak. Most of these units are mounted under floor near rear axle.

What to do for 2003 Denali air bag, service ride control light flashing


I replaced my shocks with better quality... And now my Service Ride Control is also on. The mechanic said the truck is looking for the electronic switch on the previous shocks. There is a switch they can install to over ride the warning. Don't know if you had new shocks installed, but thought I would mention it.

My 2001 yukon denali is saying serevice ride control what does that mean?


Seems like a common problem with these trucks. I thought I was the only one. I just posted this comment for someone who has a 2003.....I'm not an expert and not sure how widespread the warning message can be, but in my personal case: I have a 2001 Yukon Denali.....I have the same problem and have for many months. I took it in a few times and the GMC Dealership finally told me that It's the ride air bags. In my case they are leaking. Its not the same safety airbags in the front dash to prevent injury...but these models have air bags under the truck that automatically adjust to level when weight shift...you might hear the occasional sound coming from the back while driving or when more people are in your Denali. To me it sounds like a power tool. The Service tech told me it's not harful nor will it damage anything, but it costs about $2000 to fix, because they have to replace the whole thing. He said you may notice the sound coming on from the airbags more often because of this..because the system is working harder to adjust the weight due to the leak/loss in air. So occasionally for about a year...the light comes on....but it has done nothing else.

I hope this helps.

Location of fuse box/panel for 2004 yukon denali xl


There are 2 fuse panels in the Denali.
One is a panel on the drivers side, its on the dash but facing the door.

The ohter is under the dash and above the pedals, this one is much tougher to access.

Your Owner's Manual should tell you where the fuses are that you need to access.
