Your ABS sensors detected that your car is slipping hence activated your traction control. quite normal. I often see mine flashing when I exit a junction from standstill etc.
take ur car to a road with some sand on it.stop ur car with the rear tyres over the sandy part of the road..then press the accel hard!!
u shud see ur ASC yellow lights blinking away..
1) Position one wheel on the road and the other on the grass. Floor it.
2) Kik your steering at the junction and floor it exiting. (Look out for cars)
3) Go to Ikea's car park. Stp the car and floor it.
