There may be a problem with one of the wheel speed sensors. If they're reading more than 2 or 3 mph difference, the ABS system will think one wheel is locking up and activate the system. You'll need a scanner to access this information in the PCM. Also, check for codes in the PCM. It may indicate which sensor or what the problem is. Get back with me if you need help.
