I tried jumping the bike when the problem started, as I thought it was a dead battery at first. There is no response or activation of the bike in any way except for the subkey id error on the screen. no fuel pump, no needle sweep, nothing. it's as if a stranger with no fob tried to activate the stove key...nothing, except I get a message on the screen.
the only thing that makes me skeptical about the connector issue is that there are some bikes slightly older than mine, with higher miles, and have sat in harsher salt air, and don't have my issue. My bike is garaged every night (except for being out of town) and i'm 20 miles from the ocean. I would think this issue would be more common if it were just that. but then again, i'm no expert.
TJ, I know your longevity with this group, and I'm really wanting to help you in all sincerity, I know this has to be a hair pulling event... I feel bad;
Ok, I have repeated it now 3 times, but as for an "answer" I'm getting "no, nothing was repeatedly unplugged and re-plugged in, multiple times, to insure the connectors are scraped clean of any oxides present".
I can't say much more to reinforce this suggestion. many of these wires are connections allowing very low voltage signals/circuits into play within the smart chips and such.. any resistance whatsoever can be invisibly restricting a 5v signal, to a lower below threshold that causes errors in communication.
as for the Subkey ID Error, yeah,
maybe someone slapped their passive chip up against your keyswitch, and pressed the key down, to activate...
this would give that error.. now, it would seem to require you to invoke the on-board diagnostics, and go thru, see the codes,
and erase them.. maybe the code being stored is taking precedence over everything else currently, and once erased...and then the battery connections removed, let sit for 10 minutes, and reconnect...and that invoke/erase code procedure revisited; may not re-appear.. I dunno... try it, it's free... it just seems as if all the "simple steps" are being bypassed, and not done so far, in a complicated and tail chasing search.
If you are pressing the key down, and the screen is coming "alive" and giving that error, it sounds almost like someone "stuck" a passive chip against your ignition lock nub... and taped it on...
