Clearing the codes with a scan tool. If it has been repaired, then the light should go out when the fault no longer exists. If it is a hard fault, the message will come back in a short time after clearing.

Thanks for the input. I have been unable to find some with a code scanner in my area, that will pick up Cadillac codes. It started when it got cold out, it think there may have been some water in the air line and possibly made a blockage. Because everything seems to be fine.

Once again thanks.

Is there any way to manually override the air suspension on this truck? The truck is sagging and the compressor is not automatically lifting it.

Check to see if the armlink from control arm to frame is okay. This is what the computer uses to set ride height.

I had the compressor go out on my escalade. I replaced all the shocks with Arnott brand replacements. I also replaced the compressor with APDTY 050111 Air Ride Suspension Compressor w/Dryer & Steel Housing (Complete Plug-n-Play Assembly For Active Air Suspension Systems Replaces GM Part #: 15254590).

The issue is that I'm still seeing the service ride control error on my dic. I hear the compressor running and I've pulled all the trouble codes that I could find.
P0522
C0040
C0196
C0455
From my research I am unable to determine which of these, (if any) are causing the error.

Did you clear the codes when you did the repair or did you just pull them? Is everything working properly?

What trim package/level Escalade is it?

I did clear the codes and the service ride control came back on the DIC within five minutes. It is is just the base model.

P0522 indicates Engine Oil Pressure switch circuit voltage low and would have nothing to do with the air ride system.

C0040 is a front wheel speed sensor circuit issue. This could (but probably would not) affect the ride control system.

C0196 means Yaw rate System malfunction. Possible, but doubtful.

C0455 Steering Position Circuit Sensor malfunction. Also not terribly likely.

It actually sounds like you have got a problem with the Body Control Module. I would head over to a junkyard and see if they will let you swap modules around to check yours.

I was wondering how to clear the message on my dash "service ride control." I have done just about everything I can think of in order to clear it out but it is done, no good. I replaced the air shocks, air compressor, and checked all fuses. Any more ideas?

Shame you did not get a diagnosis and would not have wasted all that money.

We need the code so we can further help you.

Self leveling system does automatically level out the vehicle. Is there a fuse or relay for it and where is it located? Also, where is the leveling sensor located? If you have to replace the compressor motor do you only have to disconnect the hoses at the motor or on the shock?

The is a pump, height sensor and the shocks. See if the pump comes on, if it does no the pump may be the issue. If it does, the shocks may be bad.

The system needs to be checked. The compressor, relay, height sensing valve and the shocks for leaking.

Not a simple process. You need a shop with a scan tool that can turn the system on and off.
