This may be a dumb question but I would assume one can use a Diagnostic Tool, i.e. a ODBII scanner to pull the code off of the ECU right? Or is there a specific yamaha tool which only a dealer has. Just wondering since my check engine light just came on and I'm trying to figure what code is it throwing. Ive been having idle problems lately...I've read this may be due to the PCIII i have and not having the correct maps. Thoughts anyone???
