You might have gotten ice in the driveshaft splines which could have knocked
the abs sensor out of spec.....   The sensor puts out A/C voltage....  to ck,
disconnect the connector above the sensor, spin the wheel, you should get a
voltage.....  What you get is less significant than the fact you get
something......  If you get nothing then you need to move the sensor in/out
till you get a voltage....  I would get the plastic spacers (about .80 a
piece) that go on the tips of the sensors, this should prevent you accidently
going in too far....  If in/out gives no voltage then you prolly have a bad
sensor, but given the circumstances of "fault" I would not believe this the
case........   The abs controller is a self diagnostic unit....  If one of
the sensors gets no reading the abs defaults to off......  A long shot could
be your rear diff lock engaged and didn't dis, but I would think you would
feel and hear that prollum......   If that's the prollum, quick, go race Glen
Powell in NH.....  <:~)......

Definitely sounds like a sensor either faulty or no reading
