The ABS system is actuating because the control unit is seeing one wheel speed dropping to zero before the other three.This generally means there is an abnormality with one of the toothed sensor rings.Remove the road wheels and examine each sensor and toothed wheel in detail.Look for cracked sensor rings or excessive rust build up.
