'99 PSD ABS light & Speedo

[McCracken]

Recently when I fire up the truck my ABS light won't go off and when I take off down the road the speedometer will not read until I get above 35mph. I googled it and this a common problem but I never could find the answer. has anyone here had this issue?

sounds like rear diff sensor. Its over the center with a plug. Its like 15$ at napa

I went through this recently,I replaced all the speed sensors, and things like that.Turns out it was the main computer.

would a code checker pick up on any of these things? ie - bad sensor, computer glitch, etc.?

ABS light is probaly caused by a worn hose. Check the lines for wear
