Okay it seems everybody is watching this thread, but except for checking the continuity at all four corners, there does not seem to be a diagnosis for the intermittent ABS light. I asked the Ford dealer about it and they wanted to replace the ECU; but I think they were just guessing. My code reader does not give me any hints as the ABS light is intermittent, and seems to reset whenever the ignition is shut down.
Frostie, did you replace your ECU yet, and how big of a pain was that job??
