The ABS module should still provide communication to the speedometer as long as the module is reading an analog signal from the speed sensor and it has power and ground and a good ignition source. The ABS partially disables the system and turns on the light but communication still carries on for the rest of the system. It just means you have no ABS brakes. If the light is on, that should be a good sign.
What do you mean that it "pops the ABS light"?
I am resurrecting this thread. I did all this for nothing it seems. I had replaced the rear axle the sensor was too far from the tone ring. Im an idiot. Where's my sign?
