1998.5 Cummins Speedometer and ABS problem

I have a 1998.5 24 valve cummins in a ram 2500 and I have been having intermittent speedometer problems. My abs light has come on and also my brake light on the dash. When my brake light is on my speedo works. When it turns off my speedo goes out. I have replaced my sensors and i have checked all the wiring from the speed sensors to the abs module. I have no communication between my scanner and the abs module and when i took the truck to the dealership with a junk yard abs module to have it reflashed they said they couldnt get it to accept the vin number. I then took the truck home and plugged in my scanner and i could not communicate with the new module. And I put in my old module and could not communicate with it. All fuses are good. Im really at a loss and im not sure what to try next. Hence why im posting on this forum.
