anti lock question
short version: please learn me how to check my speed sensors for proper operation
long version:
in my 86, i have the anti lock warning light illuminated. i broke out my diagnostic computer (short copper wire) and got a code 24, vehicle speed sensor.
This would be all fine and good, except I dont know which of the five sensors is bad. My Chilton's manual says that I need to short pin H to ground with my diagnostic computer, but 86 vettes (or perhaps just mine in particular) dont seem to have any contacts to connect to where pin H should be.
I strongly suspect that I have two seperate speed sensor faults, to be honest. I sometimes lose indication of speed when I'm driving and I believe that is possibly due to poor connections on the tranny speed sensor. I know how to check that one out and I'm gonna get to it tomorrow, but I don't know how to differentiate between the wheel sensors to figure out what is causing my anti lock light to stay lit.
UNLESS.... the vehicle speed off of the tranny is also an input into the abs system?
any input would be GREATLY appreciated. thanks guys.
