If you hold the trip reset and turn the ignition on you get a set of codes on the odometer readout. I'm searching for what these codes mean but can't find them anywhere. Right now, my readings show:

D01 CLR
D02 SET
D03 CLR
D04 CLR
D05 CLR
D06 CLR
D07 CLR
D08 CLR
D09 CLR
D10 CLR
PPU

I assume that D02 SET means a code has been set. In my searching, I found no reference to these codes. My 03 Fat Boy is carb'd.

 

Have no ideas on the codes, but would like to tell you that your bike is looking great! Nice job!

 

From what I've found it seems to be a speedo sensor error code, and power to the sensor is open.

Thanks! Yes, that makes sense then. My speedo stopped working and I recently replaced the sensor. I guess I just have to clear the code and it should be good to go. The shop replaced the sensor but I guess never cleared out the code for me.
