The codes you are reading in the odometer spot on the speedometer are for the electronic speedometer diagnostics. Is your friend having problems with his speedometer? I would clear the codes, ride the bike and see if they come back. I believe you can do this by holding the button in for more than 5 seconds on the displayed set code and this will clear the code.
d02, speed sensor power output shorted high or open, red wire
d08, speedometer power overvoltage, orange/white wire
d10, speed output shorted low or open, white/green wire
