Default Help! P1004 error

My bike is running rough today, I checked it and I get the error code P1004 - System Relay Contacts Closed EFI

Does anyone know what causes this failure? Is there something I can do short of taking it to the dealer?

I just checked my electrical diagnostic manual p1004 system relay contacts closed.Its looks like a trip to your local HD dealer
1 Use harness connector test kit (part no hd414048)gray pin probe and patch cord
2Connect Breakout Box(part no hd43876)to ECM

I think the p1004 has to do with the rear O2 sensor. Maybe your PCIII O2 sensor eliminator is going bad.
