What's the Ford fault code u3000?

The Ford fault code u3000 is diagnosed as a control module, controller area network, or wiring system malfunction that is detected by the OBD diagnostic tool. The Power train control module detects that there is an issue and there is a voltage variation from the controllers. The signs that will indicate a u3000 code are check engine light, electrical components not working in vehicle, and the car will go into limp mode which causes the car to only drive at MINImal RPM to avoid major engine problems. The causes that could potentially have the code come up are faulty power relay, short or corroded battery terminals, and defective controller. It is recommended to take the vehicle with the code to a mechanic so they can narrow down the issue causing the fault code.
