I have a theft error after changing my ECM but have re-installed the stocker. Seemed all right this morning with full display and readouts, and now time to ride but THEFT ERROR. Dash illuminated w/theft error, NO OTHER FUNCTIONS. I have never entered a theft code. Cannot enter toggle, mode or the setup menu. Tried disconnecting the battery for a few seconds with no help. Any suggestions? Bob

The service manual mentions how to clear that. Going from emmory it was leaving the battery disconnected for a longer period of time, but I don't have the book with me right now. I'll check it later if nobody else answers.

We get theft error a lot if system voltage is very low. Put it on a tender overnight and see if that helps.

An intermittent short in the harness (hopefully this is NOT your issue) will also throw a theft error. Probably not the case as your original ECM didn't have this problem, right?

Disconnect the terminating resistor (2pin connector) hanging by the side of the ecm. Turn on the ignition. If the code clear's then the resistor is bad

Thanks to all who sent advice. It was either putting the stock ECM back on the bike or something else but I put the Race ECM back on leaving the battery disconnected for a short time (about 5 minutes). Problem solved with advice from the great guys at High Country HD/Buell service who suggested just that. Wondering about the ability to switch them back and forth though with this experience I had but no need too right now. Write-up in My SOTP impressions. Bob
