If there is an issue within the engine control system, the computer turns off the vehicle stability control (VSC).
Since you have a P0303, that tells me there was a misfire on cylinder three of the vehicle. Did you notice a misfire at any point? When was the last time spark plugs were replaced?
If you clear the two codes with your scanner, do they come right back? Try this if you haven't. I suggest it because the options are very limited. Take a look at the pic below.
I have a feeling because of the misfire (P0303) the C1201 was set. If the vehicle is running properly, clear the codes and see if they return. If the spark plugs haven't been replaced for a long time, you may want to consider a tune-up.
Let me know your thoughts and what I can do to help.
