HELP - Service Stabilitrak & Service Traction Control
 

Every time I start my '07 Burban (even sitting at idle) the bell starts chiming and the triangle sign and the warning reads service stabilitrak then service traction control (off) activates within a few seconds. This keeps going on and off as I am driving and when its in the off position the trans shifts gears very hard. Looking through the "www.chevroletforum.com" site, I can see that this had been a problem in the past with 2003 and up and there are many people talking about this issue with their trucks, but I have not come across anyone who can give the answer on how to resolve this problem. HELP!

Thank you!

Welcome to the forum.:) I hope you realize that multiple postings on the same issue aren't likely to net you more/better answers on forums like this. StabiliTrak, built on top of ABS and TC, requires communication between various control modules and sensors. In your case, it sounds like something is intermittently failing an initial test in the area between the ECM and TCM but diagnosing it is going to be like self-diagnosing a chronic fatigue syndrome. A service department or properly equipped shop should be able to scan for trouble codes and go from there.

Thank you for your responding to my post- I'll have my shop look into that.

we had similar problem on 2007 suburban
 

ventura chevy dealer could not find problem with 2-3 trip until it acted up in their possession so they could track where the short was at. it was a frayed wire down by the parking brake- we live on a sloped driveway and regularly set the parking brake and i gues with rubbing or movement a wire gor frayed. wire was replaced and problem solved. we had stabilitrack light, intermittent non start , and another light i cant remmeber what it was now --very frustrating but fixed very quickly once located. like i said it needed to act up in their posession- to track down..hope this helps
