Most likely it’s inside the hub that’s malfunctioning. My scanner showed wiring harness on the right front, so I replaced the harness from the hub to the inside of of the passenger side inner fender, still got same code, I replaced the brand new hub, code gone!! This is why I always recommend replacing hubs in pairs! If one is toast the other will fail shortly! Might as well change them whilst you have the tools out! And your hands are dirty!
