What's that about fault code 19 and the ecu?
I'm not entirely sold on the side stand thing because the way it shut down, I can have it in gear and flip it down and it will just kill the bike, no check engine light or anything else. Unless im misunderstanding yall about what your talking about with the side stand. When this happened the check engine light came on and then everything went blank.
Also how can you tell the difference between a fault code and error number, will there be a prefix before the number? I'm not 100% certain on what it said because it happened so quick but I'm 75% sure it said just 19
Just keep in mind that during start and run the ECU is polling all of the sub-systems in a go-nogo fashion. Something that teeters on the edge (not a clean 0 or 1) could be captured in memory. Not to say its what shut it down but what was in memory when it went down like a DTC code to a cage. It's a condition that has been reported but is not a hard error that stops the show or warrants attention.
Gut feeling is you have bigger issues either from the glycol or something being intermittent. Do the cleaning and inspection and see what comes of it. Put a tool to all grounds and open all critical connections.
What ever you use to clean the coolant spill, be sure to rinse with plain old water as too many cleaners remain acidic and can continue their efforts even after you thought they were done. Assemble connectors with dialectric grease or Scott will come over and punish you! :BLAA:
As for riding it in that manor; it does eliminate the fuel chop issue so many complain about!
