U0001 Code
My '13 FLD starts and runs great. Everything works as far as electrics are concerned. However, I get a check engine light pretty frequently. It will come on and go off after several seconds. The only DTC is U001, CAN BUS fault. Any ideas? The only recent change was a new angled taillight lens that required me to switch to a LED bulb. Could this cause the problem?
Thanks.
Thanks.

Thank's guys for the help. I followed the instructions to have the BCM "learn" the new LED bulb. I thought that had fixed it, but after about a 50 miles ride it started coming on again. I tried swapping the LED bulb for the original. Again, the light was off for a good long ride, and then started to come on again. I swapped back to the LED because the tail light lens was getting hot. This afternoon I "taught" the system about the LED being back in place. For good measure I went through all the other light functions. We'll see tomorrow AM. The CEL will come on for only a few seconds and then go out again. Always the same generic code. Very frustrating, but I think more of an annoyance than a serious problem. I hope anyways.
