If you do have a capable scan tool, I would go into the ABS module and check its live data for vehicle speed sensor signals, you should be able to read each wheel sensors signal from the ABS's live data list. And I would think the same of the Cluster, it should also have live data PIDs where each signal can be monitored. That way you can determine if the fault is in between the ABS and Cluster, or Cluster and ECM. This is something I would check with an oscilloscope, but a meter set on Ohms setting should be able to tell you if the circuit is shorted to ground.
Before testing though, record any other codes set, and you may want to clear the codes out and then check the scan tool data for any vehicle speed signals, sometimes with codes set modules will disregard certain inputs until the issue is resolved, so clearing the codes out will give you a window of time to check for a speed signal before the code sets again,
The wiring diagrams shown here (6, 7) show the one wire from the ABS module to the Cluster, then out to the ECM. But I would start with checking any live data if possible. Or we can go right to checking the wire integrity, the instrument cluster is not always the easiest to get to though, some can be quite difficult to get out since the connector is going to be located on the back of the module.
