Hi gang! I have a 1998 Concours (duh?) that has been displaying it's ugly SES light. I ran the diagnostic thingy - never done that before - and my battery died during the process. Well, the battery was easy enough to replace and it's running again, but the SES light came on again after about 10 miles. When I do the diagnositic thing again (this time with the engine running), I get a bunch of "History" codes (P0404, P0603, etc.) - do these mean anything? They all have "History" at the end of them and then it goes to "PCM?" - do I say YES or NO to that? Any help is appreciated!
