Help! My VDC off and slippery lights always on!
 

Recently, whenever I started my 370z and after I drive it for a little while, the VDC off light and slippery light just automatically turns on. I have to restart the engine to get those lights off but they constantly goes on after I drive it for like one minute. I bought a OBD II scanner but it says no fault codes. So I am wondering if you guys met the same problem and is there any solution to it?

Plus, mine is a 2010 base model. The previous owner got the stillen supercharger and oil cooler. Other than that is stock.
