VDC off light / VDC slip light constant on with parking brake light acting slip light

ZeN

Bros, i need your help. After a track day yesterday i've been having this issue. With everything normal, when i punch in/wot in any gear the parking brake light will come on and acting like a Vdc slip light and then come off as soon as i let off the throttle. The VDC off and also the VDC slip light will then comes on and stays constant eventhough i didnt touch it. I know my car is not spinning as this thing will comes out even when i'm in 4th gear...it usually happen past 3.5k rpm. Any idea on how to solve this, my suspect is below :-

1. Steering coupler off center (steering physically not offcenter and it track straight at highway with my hands off)
2. Low brake fluid ?
3. Parking brake sensor kaput ? ( it still lights up when i pull the parking brake)
4. Wheel speed sensor kaput ? ( can explain the constant light on vdc off and slip light but how does it relate to the parking brake light turning on? )

I'm gonna check with the dealer tomorrow and see if theres any code being thrown. In the mean time i'll like to pick your brain on this. Thanks in advance.
