So I was riding and my bike turned off. I pulled over safely, but now she wont turn over. Power to the dash and headlights and tail lights work; however the turn signals dont work. Ive replaced the ignition fuse several times, but it keeps blowing; Ive replaced the ignition relay and the turn signal module. However, the bike still wont turn over. The diagnostic reads U1064, (TSM to ECM issues) and theres a red key displayed in the dash. The battery is about two months old, the terminals are tight, but it wont turn over. It has 7500 miles, so theres that. Any suggestions would be greatly appreciated. Ride safe!
You need to work out why that ignition fuse keeps blowing! Nothing is going to change until you find and fix that. Have you made any electrical changes to your bike, or changed handlebars, worked on the handlebar switches?
When does the fuse blow? As soon as you turn Ign on or after you turn the kill switch to run or when you push the start button?
When you turn the Ign on the Ignition fuse gets power. The power goes to the TSSM, Data Link Connector, ABS module and to the Engine off/run switch on the right hand controls. Turn the Engine off/run switch to run and the fuse supplies power to the system relay, and if it's working you hear the fuel pump run for 2 seconds, it also supplies power to the start button and to the ecm to let it know the switch is in the run position. so depending on when the fuse blows will give you an idea on where to start looking for the problem.
If you or someone has changed handlebars or done other mods should be considered.
The fuse blows lows as soon as I turn the ignition to the on position. I havent made any modifications to the handlebars either, but thank you! I appreciate both of your help!
These mysteries can be a real bear to nail down. I'm going to assume you bought your bike secondhand, so there is the risk that a PO has tinkered with it in some way. While there is no certainty about this suggestion, your symptoms are typical of a problem inside the right-hand handlebar switch housing and may be a pinched or damaged wire. It is very tight in there and all too easy to trap a wire while putting things back together, such as after changing the front brake light switch. Take a look inside and inspect your wiring, but take great care with that switch, as it is very delicate. Many electrical problems are often actually mechanical, in other words down to something simple, as I've described.
I too suspect the Right hand controls but would pull the fairing and check wiring at connector 22A before I opened the housing. Check Grey to grd for continuity on 22A, if open disconnect TSSM and ECM and check 22B Grey to ground with Ign fuse pulled. Things are tight in the housing and if you do need to replace a switch take a few pictures with your phone of how the wiring lays in the housing before you take anything out.
Great advice guys! I appreciate it. Ill see what I can do as Im not sure I have all the equipment to make all that happen. Would that hand switch cause my bike to suddenly turn off while Im riding, though?

The problem is intermittent which suggests it is most likely to be due to the sort of thing we've mentioned. So yes, it could be due to a problem inside your switch assembly, bearing in mind there are several of them, each with a couple of wires. We get a steady trickle of enquiries with similar problems, which originate in that right-hand switch unit. So take a look asap, if only to eliminate that as a likely source.
Again, thank you both so much! Im not too mechanically inclined, so I appreciate all the advice. Im going to make sure I have the tools to make this happen ASAP.
