When I start m,y Chevy Tahoe my service light for the stabilitrak and traction control comes on. I recently just had my vehicle serviced for those same issues. How do I get those lights off?

 

the short answer is fix the broken stuff. To begin the process you need to check for codes in the pcm and ebcm. This will require a full function scan tool as a code reader cannot access the ebcm.
I would clear all the codes. When they return post them here. Include your vehicle info.
