What are these cryptic settings?

Hi everyone, new to the form here, but not new to Subarus. I'm coming from an '06 Legacy and currently own a '14 Legacy. My '06 had a feature where it was able to display DTCs on the odometer portion of the instrument cluster when performing a certain switch and button combination with the ignition switch turned on. So, I wanted to see if my '14 Legacy was capable of doing the same thing. I must have done it wrong the first time because I got these settings but I have no idea what they're for. I've attached pictures to show what I'm referring to. The first one, has options that range from -10 to 10. The second one, has options that range from -3 to 3. the third one shows a "3” and it only has two options, on or off. Finally, the last one shows a “5” with again, only two options, either on or off. Does anyone have any idea what these settings are supposed to be for? I was thinking it had something to do with the Eyesight system but then again I don't think that Subaru would have those settings. Just sitting in the cluster for no reason. They most likely just would have omitted them since the car wasn't fitted with that particular system at the factory. Now, going through all that, I did manage to get it to show what I believe to be a code and this is the final picture where you can see it says “B900” and from the research that I've done that should correlate to a body control module and I'm thinking the mileage that's indicated is when that code was stored. Correct me if I'm wrong.
