Hi,
If the vehicle has ABS, the speed signal is provided by the vehicle speed sensor. If a failure occurs, you will get exactly what you described. The speedometer will become inoperative, and PS, ABS, and parking brake light will illuminate.
Here is what I suggest: We need to determine if my theory is correct. To do this, the vehicle's can-bus system needs to be scanned. CAN stands for controller area network. Basically, all the different computers/modules are tied together via a few wires. A basic scan tool won't retrieve codes from the ABS module, so that is why I recommend this.
If by chance you have this type of scanner, here is a link explaining how it's done:

Let me know if you are able to have this done. If not, I can provide the directions for replacing the VSS, but want to be sure first.
Let me know.
