Ok I had the asc service needed light come on everytime I get wheel slip, stealership checked it could not find the problem.

Then I thought to my self after a few days of thinking about it, what if the speed sensors and abs ones are not working properly because the brake pads could be glazed or whatever the reason.

The following worked for me

Take off and while in second gear at 3000 to 4000 rpm apply the brake but floor the accelerator for around 2 to 4 seconds but using the brake pedal dont let the car accelerate, this will fully load up the engine, driveline, abs, and traction control.

Do this 3 to 4 times at around 10 to 30 seconds apart.

Viola no more asc service needed light coming up.

I'm not saying this will work for you but it did for me.

I'm not responsible if your car breaks or whatever issue arises from this but it worked for me.

Do this at your own risk.
