If you are not having a problem with your cruise control, just clear that code #P0577. It can be caused by moisture. Code P0031 is O2 sensor.

Why does my 1995 road King 80 c evo get sluggish after wormed up?
I have a 2012 Softail Classic and would like to know how to clear error codes.
Hi, William. Check out this video: https://www.fixmyhog.com/video/troubleshoot-with-harley-error-codes-008010/
I have a P2102 code and a PO577 code on my 09 ultra. I got these two showing up after a long road trip and the last 50 miles was rougher highway. Are these related to jarring of the bike and I read that moisture can cause the PO577. I’ll clear it and see if it returns. The P2102 might be a bad throttle issue? Wiring and corrosion I suppose??
Dale,
Those codes are not very common. There is a good chance that they will not reoccur.
If they do, you may need to invest in the electrical manual for your year and model so you can follow a flow chart in order to diagnose.
Also, if they do reoccur, let us know if anything on the m/c is malfunctioning or not working.
