Posted this once before 4 yrs ago , tried to start my 08 Ultra before check engine went off , bus er showed up , cleared codes with HD code master all was good for 4 years. Now I installed a Bikemaster LED headlight bulb with driver. A week went by & started to get bus er again, at times check engine light won't come on when I turn on IGN , have codes U1300 & U1301, trying to clear codes but no luck , any ideas where to start, headlight harness , could that LED bulb done any damage ? Have appointment to take it in this week but I hate to , any ideas would be greatly appreciated

 

Take out the parts you put in and see if codes will clear

 

Thanks I've done that with no luck
