I have a 03 650fa and I took it out riding with the guys, muddy, watery slushy mess. Runnin fine, shut it off to eat lunch and when I went to load it in the truck, it threw a esp 5 code. Cleaned some connections and fired it back up and now it flashes esp 9. Can somebody shed some light or point me in the right direction? Thanks

Welcome to the forums!

In your intro thread you posted:
I have a 03 650fa and was throwing a code 3 but I think I have that fixed but now it’s throwing a code 9.
And here:

This is confusing... what actually happened and in what order did these codes occur. One after the other or all at once? Can you brief us with a history of this machine (and all that you've done to it or found wrong with it) along with any parts that you've replaced... and whether they were all OEM Honda or not..?

Is the wiring harnesses in original condition (not spliced or hacked into)?

Do you have a copy of the service manual yet?

In most cases if mud and water is involved with throwing codes and random electrical issues all you need to do is open every harness plug pair on the bike and clean them out real good. Use tiny brushes, solvent and sprays in them if you have to, then use some di-electric grease in each set of connectors to seal them all up. This takes a lot of time (the plastics and racks gotta come off usually) but you only have to do it once. Until you do all of that... there is no point in chasing code ghosts one after the other....

Keep a smile on!

I bought it from a farmer with 1200 miles and 300 hours. Bone stock. Never been spliced into, no aftermarket parts or pieces. Other than mud tires that is the only thing. The codes it threw was a code 3. So I took the plugs off the computer behind the battery and cleaned them, electric greased th, put them back together and that code didn’t come back up, I started it and had no codes. Awesome!!! Shut it off and started it back up to double check and now it throws a code 9. I am in the process of getting a manual. I have one downloaded on my iPad but still nothing like a hardcopy

As far as I have tested yes, but I thought about getting a new battery just to eliminate that variable

Odds are it'll cost you nothing but time and some dielectric grease to clean and waterproof every pair of harness connections. Let us know how it goes if you can.
