2007 Yukon Denali XL autoride suspension light comes on intermittently


Would need to know what DTC'S - diagnostic trouble codes are stored in the module for the autoride suspension . Hooking up a professional type scan tool ,looking at input data to the module etc... Looking at a wiring diagram an testing electrical circuit's using a DMM - digital multi-meter . Reading how the system works ,what all involved in making the system work . This is how a professional Tech would go about diagnosing this .

The automatic level control (ALC) system maintains a desired rear suspension position under all types of towing, hauling and loading conditions. The following components are involved in the operation of the ALC system:
• Air line tubing--Pressurized air from the ALC compressor is pumped to each of the rear shocks via air line tubing.
• Air drier--Pressurized air from the compressor is run through a drier containing a moisture absorbing chemical preventing water accumulation in the rear shocks.
• Compressor--Supplies pressurized air to the rear shocks
• Compressor motor relay--The relay supplies battery positive voltage to the ALC compressor motor.
• Pressure sensor--The electronic suspension control module (ESCM) module provides a 5-volt reference and low reference to the ALC pressure sensor. The module receives the signal voltage that is relative to the air pressure applied to the rear shocks.
• ESCM--Controls the ALC system and electronic suspension control (ESC) system and detects failures in both. The module monitors inputs from the position sensors, and pressure sensor to determine when to raise and lower the vehicle to trim height as the vehicle is loaded or unloaded. The module limits pump activation to 255 seconds to prevent thermal damage.
• Exhaust valve--An electric solenoid activated by the ESCM to vent air pressure from the rear shocks.
• Left and right rear suspension position sensors--The module provides a 5-volt reference and low reference to all 4 of the body-to-wheel suspension position sensors. The sensors send the ESCM a signal voltage that is relative to the rear suspension ride height
• Left and right rear shock absorbers with internal air chambers and dampers--Dampens the rear suspension and maintains trim height depending on the air pressure applied.

2007 envoy denali rear wont rise


well I will tell you my problem it maybe the same happening to you, every time I park the car for more than 4 hours it will lower the rear and after I start it will go to normal high, well the car have a air leak on one of the air bags in the rear, the compressor was pumping air almost all the time because of that to the point that one time just stop working. I have to buy new air compressor and 2 air bags. I bought them at www.arnottindustries.com not difficult to replace either.

I have a 2006 denali and the service ride control just came on . what does that mean. Thanks Ray


Unfortunatley it means you have trouble with your air suspension. Fairly common on these vehicles and not a cheap fix either. I would have a shop check it out. Have you had any tire or brake work done recently because if so, someone could have knocked a wire lose from one of the shock sensors. Just a thought.

Price to replace air ride compressor pump?


I've had to replace it twice!!! The part was around $650 cdn and the labour was around $150. It is behind the rear drivers wheel (?). It is very susceptable to corrosion from road water, salt, and dirt. Call a dealer's parts department to get a price. If you can hear the pump when you put weight in the back, it could be the air shocks or leaks in the lines.

The rear of my GMC Envoy sits very low and the ride is very bumpy


If you have air shocks, they could be leaking. Check that air compressor is being activated. You can test the power to the pump if needed with a voltmeter.

Many people do switch to traditional shocks which seem to last longer and are much less of a hastle.

You can go to autozone.com and register for free online repair manual if you wish to change the shocks yourself.
