Waveforms
This is a new one.
"My ABS light comes on whenever I drive by Sambucas"
What?
We cleared the codes and drove to Galena and sure enough, just as we passed under the power lines, the ABS light came on.
These are the waveforms for each wheel.

As you can see, the right front has a crazy spike that occurs every time we drove under the power lines.
We brought the vehicle back and ran an electric soldering iron over the wiring harness and sure enough, the waves went nuts.
Kind of makes you nervous.
