Check VSA System - Acura TSX

Yesterday I started my car and had the Check VSA SYSTEM light on. I was not sure what it could be. After looking into some forums, I realized that it might have to do something with tire sizes (people using different tire size) – so I thought maybe I did not have enough air in my tires – anyway, i added some air, turned the car off/back on and the light disappeared.

This morning, I started the car and the check VSA system light came back on. So it defintely does not have to do with air. After driving for about 15-20 minutes, I pulled into gas station and turned car off/back on and the light is gone.

Anyone have any idea?
