My wife's '06 TB does the same thing during the winter. Never happens during the other three seasons. We never have been able to figure out what the problem is.
Gotcha, yeah sometimes when the ground wet or sometimes just random even when it’s dry, but then i’ll turn it off and back on it goes away

I've read somewhere that the steering angle sensor can be a factor in that, but it's a PIA to replace! So we just live with it.
Looked up a video, right under the dash, doesn’t look too bad to change, just alot of screws to keep track of.
One other Question: If a Reduced Power Event occurs (which ordinarily disables the StabilTrack and Cruise Control Systems) will that particular Dashboard Light also Glow as a result?
These Two Videos are On Topic... Yeah... they cover the Trailblazer SS Vehicles... BUT they are still Interesting as another angle for understanding the issue:
And here is the 2006-2008 GM TSB on the StabiliTrak Issues:
#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
2006-2009 GMC Envoy Models
2006-2009 Saab 9-7X
2006-2009 Isuzu Ascender Models
--------------------------------------------------------------------------------
This bulletin provides information on two different conditions.
Condition #1
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.
Condition #2
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.
Cause
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.
Correction
Do This
Don't Do This
Reprogram the EBCM.
Do not replace the yaw sensor or EBCM for this condition.
Important: From the controller list, select "VSES Vehicle Stability Enhancement System Control Module."
If routine diagnosis using SI does not reveal any obvious cause, reprogram the EBCM using SPS with the latest software available on TIS2WEB. Refer to the Service Programming System (SPS) procedures in SI. As always, make sure your Tech 2® is updated with the latest software version.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer".

Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your vehicle will have that condition.

This is another Thread that is more in the Expertise Wheel House of our SME ... @TJBaker57 that is also on topic as one Member mentions therein using this technique to diagnose his StabiliTrak Warning Light Issues:

Ultimately I believe this is the result of an electrical connection where oxidation and/or looseness is the primary cause. But, that didn't help one bit. I once found a surging speedometer due to an oil leak compromising a wheel sensor. WTF was that?
What to do? As a practice, whenever I'm working on something I always remove connectors (if I can) and treat them in a way that establishes a good connection and prevents further oxidation. I recommend we just blindly do it - always if it's reasonable.
The only problem is it's hard to identify the problems you don't have - as it is as hard to identify exactly what is happening here.
Somewhere in the system (CAN h/l?) there is at least one connection teetering between good and not, that it's likely a tiny phenomena influence by environmental conditions.

It follows on that it is just such an "Environmental Condition" being the ultimate arbiter when it comes to "Rust Jacking" underneath the Mild, Alternating Current Generation that is produced in the calculated gap in between the Tone Rings inside of the Wheel Hubs and the undersides of the Plastic Wheel Speed *Sensors*
This is a Misnomer for sure since there are Micro-Coils of Fine Copper Wire and Magnets behaving as A/C Electrical Sine Wave signal generators as the Ring Teeth pass underneath them changing their Frequency as the Wheels speed up above 3-5 MPH... or slow down. This is arguably the Best Diagnostic and Repair Video ever done on this topic and truly Spot-On for the GMT360 Platform:

In this instance, maybe not. As per the TSB posted, it could be a software update to fix this. I should do it to mine as I get the occasional light for this, especially when it's really cold. My only problem is that it was posted in late 2008 and Tis2000 may not have been updated with it as it may have been its last update before being retired. And I don't know if they fixed the issues with Online TDS and the Tech 2 as a passthrough.
