Hi, My name is ***** ***** for the delay.
I will do my best to assist you.
the codes keep coming back because you have a problem..
the problem must be fixed to stop the codes from returning.
from the way you explain the problem,it sounds as if you may need to clean the throttle body
these throttle bodies will get dirty with black soot and cause this problem
after cleaning the throttle body,then you need to clear the codes with an obd 2 scanner..if you dont have a scanner,auto zone and most parts stores will do this for free
the throttle body is easy to clean,,just remove the intake air ductfrom the throttle body and clean it with carb cleaner
well..i can upload the throotle body that may help you understand what to do

Bulletin No.: 04-08-49-006C Date: January 05, 2005 TECHNICAL Subject: Service Stability Message Displayed, DTC C0550 Set (Reprogram EBCM) Models: 2004-2005 Cadillac Escalade, Escalade ESV, Escalade EXT 2004-2005 Chevrolet Avalanche, Suburban, Tahoe 2004-2005 GMC Yukon, Yukon Denali, Yukon XL Supercede: This bulletin is being revised to correct the Subject line. Please discard Corporate Bulletin Number 04-08-49-006B (Section 08 - Body and Accessories). Condition Some customers may comment that while driving downhill and making a turn, the Service Stability message will display in the Driver Information Center (DIC). This will occur prior to ABS activation and once stopped, the message will go off. Upon investigation, the technician may find DTC C0550 stored in history. Cause The cause of this condition may be that the "Long Accel Gain" parameters in the EBCM are sensitive to certain driving conditions. Correction Technicians are to reprogram the EBCM with an updated software calibration. This new service calibration was released with TIS satellite data update version 9.5 available September 20, 2004. As always, make sure your TECH 2(R) is updated with the latest software version.
