How long has this been going on?
The ABS circuit is the most sensitive to incorrect voltage so check the voltage regulator. I'm guessing it's built into the alternator. Pull it out and check that there is enough brush extension to properly contact the armature. If one brush looks cleaner than the other, the dirty brush is worn. The regulator is a $25-55 part depending on brand and source.
