The stabilitrak system is controlled by the abs module. Its job is to maintain vehicle stability in situations where you may normally lose control by activating the abs system and/or changing the valving in the shock absorbers. When the message is displayed there is a problem in the system, could be an issue with a sensor or wiring. There are a couple of common problems with the system that require reprogramming the engine control module and the abs module. This must be performed at the dealer. The only way to know exactly what the issue is would be to have the abs computer scanned for trouble codes. Here are copies of the service bulletins regarding reprogramming.
#08-05-25-005: Intermittent StabiliTrak Indicator Light Blinking, StabiliTrak Active Message Displayed, DTC C0196 Set (Reprogram Electronic Brake Control Module (EBCM)) - (Oct 1, 2008)
|Subject:||Intermittent StabiliTrak® Indicator Light Blinking, StabiliTrak® Active Message Displayed, DTC C0196 Set (Reprogram Electronic Brake Control Module (EBCM))|
|Models:||2006-2007 Buick Rainier|
|2006-2009 Chevrolet TrailBlazer Models|

This bulletin provides information on two different conditions.
Some customers may comment on a Service StabiliTrak® indicator light along with a Service StabiliTrak® message displayed in the DIC. Upon investigation, the technician may find DTC C0196 set in history.
Some customers may comment on a blinking StabiliTrak® indicator light along with a StabiliTrak Active message displayed in the DIC during normal driving conditions. No DTCs will be found with this concern.
This condition may be caused by a software anomaly within the electronic brake control module (EBCM) that allowed the yaw offset to be falsely learned.
Don't Do This
Reprogram the EBCM.
Do not replace the yaw sensor or EBCM for this condition.
#07-08-49-006: Intermittent StabiliTrak Service/Indicator Light On, Service StabiliTrak Message Displayed, EBCM DTC C0244 Set (Reprogram Engine Control Module (ECM)) - (May 7, 2007)
|Subject:||Intermittent StabiliTrak® Service/Indicator Light On, Service StabiliTrak® Message Displayed, EBCM DTC C0244 Set (Reprogram Engine Control Module (ECM))|
|Models:||2006 Chevrolet TrailBlazer SS|
|with 6.0L Engine (VIN H -- RPO LS2)|
Some customers may comment on an intermittent StabiliTrak® light being illuminated or a Service StabiliTrak® message displayed. Upon investigation, the technician may find EBCM DTC C0244 set in history.
This condition may be induced during wide open throttle acceleration from a stop or when accelerating onto an express way during low ambient temperatures.
This condition may be caused by the ECM sending out an invalid torque request signal.
A new calibration has been released to correct this condition. Reprogram the ECM using SPS. This new service calibration is available on TIS2WEB.
Be sure to select the correct calibration part number with the description that states -- to prevent C0244 at low ambient temperatures.
