ANOTHER Buick ABS MALFUNCTION? (Enclave C0045)

Deja Vu?
We have ANOTHER Buick with the dreaded "SERVICE STABILITRACK" Warning Message!

This 2012 Enclave AWD belongs to my neighbor, so I know it hasn't been BUTCHERED before coming in for a diagnosis :)

"C0045- LR Wheel Speed Signal Implausible" is stored.

Even though I have a suspicion on what the issue could be, let's PROVE the root cause with an OSCILLOSCOPE first, before tearing anything apart and replacing expensive parts!!
