knicksmsg, MOST of them are posted here in our "factory direct" area.... but like benjaming said, they really aren't usually out there for the public. They are made to speed up diagnosis for the techs.... that is there sole purpose, so Honda or most other manufacturers haven't seen a good reason to share them. I DO think it's a good thing to share, so I do it. I think too many dealers are hiring under qualified techs since the qualified ones are getting harder to find. Like nearly all the service fields, it's becoming a thing of the past. People don't want a job they have to get their hands dirty anymore.
Anyway, good luck on your quest for a quieter car!!
