I am hoping I can get some help here. I bought my wife's 2015 Street Glide Special used and not too long after it we were riding and the ABS and check engine lights came on. We stopped, turned the bike off and restarted it. The lights were now off. This happened a couple time in the 4000 miles she has ridden it. Fast forward a couple months and I changed out the bars for 10"ers. After a couple rides the lights were more intermittent and I lost the clutch side controls. I took it back apart and I found a recessed pin on the HD extension cable I used for the bar install. After I got it all back together everything is working great (controls work and no light right now) I went through and cleared all the codes. Right now I have code U0121 hard set on the BCM and RAD circuit. Dose anyone have ides on what to look for next to fix this U0121 code issue I am having now?

Thank you in advance for any help you can provide.
