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
