getting the yellow flashing triangle at take off

[marsman]

Hi, I have a 2002 Volvo S60 2.4T FWD with about 248K mls. I am seeing the yellow triangle flashing at take off or when I accelerate hard from the merge lane into traffic. Does my car have speed sensors? or could it be due to a failing BCM?  Thank you for your input.

The flashing yellow triangle is on because one of the wheels is spinning and the traction control is trying to keep the wheel from spinning.
