P0581 code

[Blvdst]

My ABS and Advance track light came on after hitting a pothole at Freeway speed the other day, the 4x4 high light will flicker occasionally. Ther cruise control operates properly as does everything else. Anyone got any ideas where I would begin to clear the code and lights?

@Blvdst
The code is not related to either icon, is related to speed control malfunction. However, codes of non-specific intent are used as highlights and warnings. My GUESS would be that, being Advance Track equipped, a wheel speed sensor was knocked out of commission. imp
