Okay, yes ... There is already a bunch of these online. But while many of them seem to have most of the codes, I'll be damned if I could find any of them that had all of the codes. So I combined all of the lists I could find into one - cleaned, sorted, and de-duplicated - database, that I thought I'd share here for anyone interested.

So if you see anything missing from this list, let me know and I'll add it.

LOL - ^Beat me to it^.

On a side note: The site is specifically designed and coded to be easy to print/save/swipe - So yes, feel free to grab an offline copy in whatever manner you wish.

there is a new code C0077
I'll have to lookup what it means, and see about getting it added to the database this weekend.

Thank you

Nice, great job, how long did it take?
Roughly about 2 days total to harvest all the existing lists, massage them together in Excel, and stick the result into a Quick-N-Dirty MySQL database for the page's backend.

b1554......A "B1554" fault code on a Harley typically indicates an issue with the "Right Rear Turn Signal Circuit," meaning there might be a problem with the right rear turn signal bulb, wiring, or the relay itself
TSM part# 68920--07
Damn it man, caught me napping - Just added this one to the database.


Yes, that is one of several DTC lists that were combined to create the database I offer a link to in the first post.
