So I'm currently stuck on the side of the road as I write this. My TFT display started displaying multiple errors including transmission error, check engine light. Also a five digit error code that started with the letter t I don't remember the rest. My speedometer, fuel gauge, and RPM gauge all went to zero and wasn't showing anything. Put over the side of the road made the mistake of shutting the bike off now when I press the ign ition see happens lights don't turn on or nothing. Any thoughts? When all the error message popped up the only thing that happened is I was using my cruise control and then it stopped when that five letter error showed up that started with a t. Bike acted fine otherwise
 
Also notice that my ignition fuse was blown so that's kind of leading me towards that area of troubleshooting but I don't really know much at best I'm a amateur YouTube mechanic and that's being generous. I had a spare fuse in a replaced it but still nothing's working.
 
Main fuse was fine. After sitting for 2 hours the bike actually turned on and started and stuff. I didn't have my scanner to check the error codes on it though. It decided it was willing to start once I had it on the trailer. I'll have the battery tested too I replaced it already with a different one last writing season. It's one of those glass mat type ones
 
This is off the wall may or may not be correct.
Most of the newer bikes have a tip over sensor (my 07 has one that never worked)and if it triggered a code you then have to cycle the ignition switch 3 times b4 it will start
Or maybe wait a couple of hours b4 it will start.
Just guessing.
 
Tried connecting to my thing to read the computer and it would turn on sometimes but wouldn't start because it's not detecting the transmission being a neutral. And giving me a transmission error code on the TFT display
 
Not sure what that last post meant, are you saying you tried to read the codes with an OBD reader? The bike will not start if it's in gear and the kickstand is down. The tipover sensor will also inhibit start if it has failed. The OEM battery is an AGM (acid glass mat) type so the battery you have is compatible with the electronics. Start failures can also be attributed to key fobs. The start sequence in the manual states:
▼ Make sure that the master ignitionswitch (if fitted) is turned to the ON position, see page 64.
▼ Pull the clutch lever fully into the handlebar.
▼ Press and hold the QUICK START position on the engine start/stopswitch until the engine starts.
Make sure that the transmission is in neutral.

If your gear position sensor is faulty it might inhibit start since the ECU cannot determine gear position status.

So when the TFT screen is airing out my OBD2 scanner will not read the computer at all. That's what I meant sorry I was really tired but a long weekend. I have an aftermarket battery cuz I replaced the last one and I did test on it and the battery is a okay. My OBD2 dongle connected at first within my screen started flashing between transmission fault check engine light, TCS disabled check manual, and it would flash between all those really quickly. When it started that flashing through all those errors that's when my OBD2 dongle lost connection and wouldn't read error codes or anything
