abs codes

[mott]

I hope someone can help. I have a 94 Jimmy 4wd. I get an abs code 51. My up to date hanes book does not show this code specifically. Does anyone know what a code 51 is? Thanks in advance

Now, if the result is a bad bpmv, do this. Clear the code, bleed the brakes, and go find a place where you can lock the wheels up and they'll slide (dirt or gravelly road). This will cycle the abs and may clean up the valves enough to start working

Thanks for the info. I will clear the code and bleed the brakes and see what happens.
