[V6-12v] ABS Light On

[Clive Young]

I did some extensive troubleshooting with my ABS a couple of years ago and
posted extensive testing also. Unfortunately it was on a computer I know
longer have. Anyone else have these posts , it included test points and
voltage values. 

Mine turned out to be a speed sensor on one wheel had backed right out.

My ABS light is on again.  I thought I had found the problem.  When the
light comes on the rear diff also locks up.  Green light comes on in the
console.  I have the 3 volume set of Haynes manuals and they are almost
totally useless.  Parts diagrams but no trouble shooting.  I checked all
electrical connections that I could find.  Under the rear seat and under the
hood.  Tried removing a speed sensor but didn't want to break it.  What kind
of measurement is required to test a speed sensor?  Car is 1993 wagon
CSQ100.
   
  Best regards,
  David
