Ran across an interesting chart for 2000 Windstar ABS codes (4WABS). For those that don't get the actual codes read, this chart helps narrow down the errors a little if the light comes on at specific speeds, time durations or at Key On. Even if it doesn't pinpoint the exact ABS error, it helps limit your search a little.
