ABS Valve relay

Hi

I got the fault codes 13 and 51 on my ABS.

I did measure the resistance on the rear right wheel sensor and it got the same resistance as the one on the left. I guess next step is to get the car up and check what happens when I turn the wheel. :)

The valve relay I have not had the time to find and measure. But my question is, what is the job of the "valve relay", since my ABS system seems to work fine?

Edit: The rear ABS wheel sensors was measured to around 980 ohm.

No idea, never done ABS work on a Miata. Definitely following.
