low side racing

I have a 2010 wr250x and the display is flashing EP I have looked in the service manual, I have scoured the internet, I have called Yamaha (no help there) and I have only seen on other instance of this and nothing was known as a remedy There was a video on youtube showing the same thing, however it is gone now - this is just a picture but represents what is shown wr250, wr250r, wr250x, wr250f display flashing EP, display EP error
