abs light comes on for no reason on 2004 GMC Sonoma

why does my abs light come on when there is nothing wrong with the brakes

Asked by for the 2004 GMC Sonoma
The ABS light comes on when there is a problem with ABS system. If the regular brakes are in good condition then they will still work ok but in a panic stop the ABS system will not work when light is on. Needs diagnosed by qualified shop. Most problems come from sensors.
