Just pull the fuse, it's under the hood in the fuse box

Are they coil overs?

If so- you remove them & have a shop put them

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.

SERVICE AUTO RIDE LIGHT


This could be a bad shock absorber, a bad air compressor, a bad electrical connection or some other weird problem. Because of the expense of the repairs to the auto ride system, I would think about replacing the shocks with non-auto ride ones and living with the service light.

My autoride suspension is not working


A ton of things could be wrong with your autoride system. If you have more than about 70k miles and haven't replaced the rear shocks ($500+ EACH!!! at the dealer), then they are probably leaking out. If they leak out, then the air compressor will always run. Eventually the air compressor/ride level sensor module (located on the driver side rear wheel on the inboard side of the frame, $300+ at the dealer) burns out because it's not designed to run at 100% duty cycles. After the air compressor burns out, the Electronic Stability Control module (in an XL, located inside the passenger side rear wheelwell trim, next to the third row seat, $300+ at the dealer) will probably short out. If your autoride isn't working and you don't get a "Service Stability" message, your ESC module is probably going bad.

It is possible to convert to regular shocks, but to keep the Stability Control (still has to control your brakes and front variable dampening shocks during "evasive" maneuvers), you have to insert some 1/4 watt resistors in to the ride height sensor connectors (can't remember what values, but I'm sure you can Google that) so that the Stability system doesn't throw a code. Not that it matters, but the message can get annoying if it's always there to nag...

My dealer quoted over $2500 to replace the entire system. I figure I can find the control modules from my local junkyard for $300, and the shocks from ebay for $350 for the pair. Be sure to match all of the GM part numbers, and keep an eye out for an upgraded Air Compressor module - GM released an update that is heavier duty and more water-resistant than the first design. I don't remember the part number, but my dealer included the upgrade with my quote.

Oh, and the only "easy" way to test the modules is with a Tech 2 tool. Otherwise it's lots of testing with a 12-volt source and a couple of multimeters and oscilliscopes...

Good luck!
