I have a 2007 Trailblazer with 106,000 miles. The stabilitrack light flashes 4-5 times when I begin accelerating. I recently had the vehicle in for repair and they replaced the sensor. Wheel bearings where replaced at 80,000 miles, recently tie rods have also been replaced. Occasionally when accelerating, the car will tend to stall, or when braking, it is as if the ABS system is kicking in. Not sure what else to check.
I Think You’re On The Right Track By Suspecting The ABS System.
Has It Been Scanned For ABS DTCs (Diagnostic Trouble Codes) ?
(A Regular OBD2 Scanner/Reader For The Powertrain Won’t Read These.)
Here’s A Possibility.
GM’s Got A TSB (Technical Service Bulletin Written For Their Technicians) That Discusses “Intermittent Stabilitrak Indicator Light Blinking” On Some GM Models, Including 2006 - 2009 Chevrolet Trailblazers.
The bulletin mentions a “Service StabiliTrak” message in the DIC (Driver Information Center).
Do you get that message ?
When checked, technicians either find no DTCs stored or a DTC C0196.
This condition can be caused by a “software anomoly” in the EBCM (Electronic Brake Control Module) that allows false learning of the yaw offset.
If this is it then the fix is to reprogram the EBCM. No parts need to be replaced.
