OBDII Scanner GAVE Me An Engine Light
So, I have a 2014 STR ABS. I also own a fairly nice OBDII code scanner that does live data. The other day I plugged it in to see what sensors I could read. But, the scanner never turned on. Upon a couple more attempts, I realized with the scanner plugged in, the ECU would shut off. I gave up and went for a short ride only to discover it tripped an engine light. It went away after 3 heat cycles and bike runs great, so, I assume no damage was done. But, I'm curious as to why this happened and if anyone else has had this problem before.
