Flashing D fixed! Service manual error...

[singlecoil]

I took my 2004 EX to the dealer the other day to have the flashing D diagnosed for $90. After about an hour, they said the number 4 pressure switch was bad as indicated by testing and the code. They said the part was about $60 and labor was .75 hours. So, for a total of about $220 i was out the door and psyched to have the problem fixed.
Unfortunately, the light started flashing again on the way home. The dealer was very apologetic and wanted the car back as soon as possible. I took it in this morning and it took them about an hour and a half this time. The code was for the number 4 pressure switch again, so at first they wondered if the switch they put in was bad. After repeatedly troubleshooting it, they discovered that the service manual had an error in it. On the task for replacing the #4 pressure switch, it leads you to the #3 switch. So they changed out my #3 switch, thinking it was the number 4. They contacted Honda and pointed out the error in the manual. Apparently the switches are identified by the color of the wiring harness, which mentioned the incorrect color.
I'm not sure what years that service manual covers, but if others are having problems with getting the flashing D to stop, maybe your dealer is changing out the wrong switch too.

Nice, I happened to change my 4th clutch pressure switch myself last year. I guess I changed out the right one then - I have the factory service manual for my car. I don't think I even looked at the wire colors, just the picture it had in the manual Anyways, good to know now.
