Hello
I have looked all over to see where the tie of the ABS, Brake and speedometer connects. The only place they all connect is the combination meter... Which looks like the cluster itself. There are extensive tests it looks like you can perform with a volt meter if you would like those.
As for the ABS and Brake warning light. Please check your brake fluid and make sure it is where it should be. This will set the light off and make sure your parking brake is all the way off. I would set it then release it.
The only thing I see with the speed sensors is you have the vehicle speed sensor which you keep replacing and there are speed sensors on all the wheels. I can send you the checks for those if you would like.
You can remove each wheel and really inspect the sensor and the rotor really good for any damage, missing or damaged teeth. What I mean by that is your rotors will have a gear on them. The speed sensor reads the teeth as they rotate. If one is clogged with dirt, a sensor with a wire that is pinched etc. Look them over really good.
If you can get me the exact code and what it says that may help too. You can go to Auto Zone or O'Reilly's and for free they can pull the codes to the car. Most important. Once they check your codes, if they find something and you don't get it fixed and need to get back with us, please make sure you tell us exactly what the code was, number and all. Example, if the code was E0568 O2 Sensor bad. Then make sure you give us all of that. While there for free also they can bring their tester out and check your battery, alternator and starter.
Please do the above and let me know if you want all the checks and I will send them to you.
