Not really, unless by using a meter or oscilloscope to test, but that requires a known good ABS sensor.

They are BRAND NEW BMW equipment sensors.

The Computer shows No sign of any sensors. Old or New. When data logging the speed remains at "too low"

Agreed, all connections are secure. No idea what the correct resistance should be. Information is NOT out there.

I have trouble believing that the bearings are bad...but you never know. Can these bearings be "demagnetized" by a security check scan by Homeland Security????
best of luck with it!

WHO knows. lol
All I know is, the car went into the shop working fine, but with bad bearings. The wheels were about to fall off. NO JOKE.
Changed bearings, and now neither rear speed sensor works. Replaced both Speed Sensors. and NO change. Ive seen it talked about where bearings were just BAD. I have a set of OEM BMW, which are branded SKF, bearings sitting here, and replacements from the auto store to replace the ones we purchased. We Purchased TIMKEN, which were branded *** on the bearing. The replacements from the store are Beck/Arnley, and I havent gotten my eyes on them yet. So we will see.
