I have a question about my 2007 Chevy Impala. The check engine light is and I scanned. I got a code P0650 but the service stabilitrak/traction control light is also on. Are these two problem related or is it two separate problem. That do i need to do to fix this problem.

 

Its quite possible. the pcm is involved in traction control/stab control...so some pcm system malfunctions will also disable trac/stab.
