And? You paid for it. What did the indy report?

You should post your numbers in the aforementioned ABS thread.

I'd love to know HOW they hooked up the diagnostic tool to tell you that, for sure.

I am suspicious that a good DMM wouldn't have told you what you ended up paying an Indy to tell you (and for less money than the cost of the good DMM).

But, the good news is that, if it was the wheel speed sensor, that the problem is resolved.

As many have said, most of the time it's a single wheel speed sensor (which can be diagnosed with a 'good dmm') or the steel wire lifted off its gold bond pad inside the ABS control module.
