Pull the rear bulbs out an inspect them for dark marks on the glass or abnormalities in the filament.
A bulb that works but is on the verge of failing will trigger the indicator on the dash as well.
Failing that, the lamp failure module is very common to fail, triggering the light as well. You can pry the box lid off and usually see burn marks on the circuit board when this happens.
The lamp failure module is located behind the left rear tire area in the trunk.

You have to use a scanner and pull the code out that is causing the check engine light to come on. whatever code/codes you find are probably related to vsc light.
Good luck and keep me posted
