What does it mean when a SP500 speedo displays things like "SDrd"? We can't get it to display miles, only hours and other things that seem to be useless garbage. Everything else works.

 

Any info on the speedo would be appreciated, I found nothing on this with a search. Is there a way to reset (not back to zero) by unhooking the battery?

 

I have noticed people saying that you can put newer speedos in diagnostic mode with instructions from the owner's manual?? If yours does this, I would try diagnostic mode and see what happens, or maybe your stuck in diagnostic mode??
