Update....
Upon inspection of the Dash, I find that it has already been Potted and EBR tells me that based on it's serial number it is not the original one for my bike. Also told me it is one of the later, improved ones that are "post" "Comm Error". I contacted the Dealer that I purchased the bike from about any repair history on it prior to it being sold to me as the first owner. They said that other than a first 600 mile service, there were no other issues or services performed on the bike. It was their Demo bike when I purchased it new with just over 600 miles on it. The only time I had the Dash out was for the Free Dash and ECM Firmware upgrade about last year. EBR said they didn't switch it out, so it's a mystery how I ended up with a later model dash. Back to the troubleshooting..
After clearing all the faults, I re installed the original ECM and the bike still had an intermittent fuel system fault that continued to get worse. I noticed that it also showed a zillion other faults after swapping the ECM. I cleared them all and put the APH IDS ECM back in to continue with trouble shooting. Upon swapping the ECM, I got more Faults, including the Comm. I cleared them all to start fresh and was only getting Fuel System Faults from then on. The fuel pump issue progressed to a completely non-working fuel pump while tinkering in the garage for bad grounds, chaffed harnesses etc. Working backwards from the pump to the wiring on the harness to see where things were changing from good to bad electrically, I found that the four pin Weather-Pac looking Fuel pump connector, to the main bike harness, one of the connection had a bad female contact on the Pump ground wire. There are little spring loaded wiper strips inside the female contact that keep good pressure and contact to the male pins. The "wiper" was completely pushed back out of the way and was not making contact with the male pin when assembled. I tweeked the wiper back to the center of the contact and reassembled the plug. The bike started instantly. I re-assembled everything and four short separate (close to home) test drive trips totaling about 150 miles finds everything working perfectly, no faults and the bike runs like a scalded cat. So, so far, I think my Comm fault may have been just from swapping out ECM's within seconds of turning off the key and the Dash hadn't internally gone fully off like it would if you let it sit key off for a half an hour and then swapped parts. As for my bike having an updated Dash that supposedly wasn't even made when I bought it? Who knows, The EBR guys say that they would have sent my original one back that I sent in for update so the mystery goes unsolved. Hopefully with the newer Dash, the Comm issue will never return to haunt me...
Happy mike...
