What do these DTC codes mean?
Ok, so while riding today, the speedometer quit on me, and after cycling the power all was well, except there were codes logged. The codes logged were as follows: b1004, b1005, and u1016. I know b1004 and b1005 mean "Fuel Level Sending Unit Low Instruments" and "Fuel Level Sending Unit High/Open Instrument" respectively. But what does that mean? Also I've read that the u1016 code is common with the thundermax and I shouldn't be alarmed about that. Any help would be appreciated.

dont worry about them. just a bug as you lost the speedometer data. just update to the latest firmware and reload your map. i had that happen 2 times and after the latest firmware it has happened again. just turn off the bike off and back on and your ok. also after you ride a few hundred miles read the learned offsets and then write the learned offsets and you will see a nice change.

Thanks for the reply. I kind of figured they were all related. I updated the firmware at the beginning of the month, is there a new one since then?
Yeah I've been doing that since I got it a couple of months ago. It's great, the bike just keeps getting better and better.

Thundermax still has not fixed the issue with their unit... all you can do is cycle the ignition... I've had the same happen twice since I put the ecm on back in april... last time it happened was about a month ago...no new info or firmware updates at that time.

i re-flashed the firmware and started over and it happened once again so i will just live with it as it does not seem to hurt anything. I have only had it happen once after each flash so maybe it has to do with timing and wont come back.
If that is the only problem i ever have then i am very happy with it.
U1016 Loss of ICM/ECM Serial Data Instruments
