VINERR?
Lasted a couple seconds and went away
Bike was running normally. No other trouble lights came on.
Got home and went into diag mode and SPDO showed the code P063000.
No other errors or problems.
What could cause this?
Check for any codes, there might be a U code stored.
Harley Trouble Codes
Basically all the main modules Speedo, BCM, ECM communicate with each other and look for the linked modules Vins, serial number etc. if it doesn't get the correct number or at all, it will cause an Error Code.
As said normally VIN Error is associated with the ECM.
As it did not repeat I would suggest check the connectors and wiring for a slightly loose fit, not fully in or damage at the ECM, it may have just been a one off and you just happened to see it!
I have a video of what it was doing.
Edit to add: Just saw your other post about adding new bars. Did this start before or after the bar install? Might need to go check all your connections and wires.

Speedo connection seems a much more likely suspect than the wiring for the bars

I actually havent seen the VINERR displayed again since that one time, but it was so quick before it may well have happened again and I just didnt see it.
I did see the SPDO trouble code again though, and cleared it again. This issue does not seem to merit any kind of indicator light on the speedometer display.
I only know it happen3ed again because I went into DIAG mode to see, and it was there again.
Its important to note that the bike runs perfectly normally, and by normal I mean its amazing the torque and power and sound. Its got it all
so whatever is causing this is extremely transient and isnt affecting the performance. Starts right up everytime and runs great.
so my first move was to unbolt the speedometer and reseat the connector under there. That was not the issue apparently
My next move will be to lift the gas tank up and reseat the connector on the bottom of the tank. Hopefully thats the one.
These two are really the only ones I messed with that seem like they could cause this...
Will be doing some work on it this weekend and will be trying this next one...

The rest were hand controls. signal lights, etc, and dont seem likely culprits, especially since they all work perfectly...
