FI ERROR 38
« on: July 31, 2019, 11:33:01 pm »
I think that maybe some of you have or will have the error code 38 (ECU communication failure) come up one day. I had it flashing on my dash today and after checking the various possibilities as to why, I found a mouse nest under the tail section of the bike. They had chewed through some wiring which I think may control the rear lights and which was creating a short. After repairing the wires all was well again. So I thought I'd add my two cents to the forum. I'm not a electronics guy by any means but apparently any wire short not directly related to the ECU will cause it problems. Hope this helps someone out one day. Oh, I'm riding a 09 Concours with ABS.

Thanks, good that you were able to track it down. Some of the electric issues can be headaches to figure out.

Adding that to my troubleshooting guide.
ERROR CODE 38 - Check for BIKER MICE.
