No start tft error

if you are going to start checking
if it was me i would take a multi meter and set to dc volts and go right to the battery bolts then to the all the battery terminals (late models have a habit of the bolts being loose)
if nothing found then move on with a 12 volt test light clamp on neg side then touch all the fuses on both sides to see what happens only on one side fuse is blown.
also if you want to check the obd connector on the bike i believe that i can find my picture of the obd telling what the terminals are so you can check to see if you have a good positive and a good negative coming from your obd connector on your bike. failure to have a good pos or neg will result in scanner failure.

OK, the first thing I would check is the ground from the battery terminal to frame was clean and tight. Next install your OBD reader and connect to the ECU. Does the ECU stay in communication with your OBD reader? Are you using TuneECU or some other software to read your ECU?
 
I'll be doing that tomorrow. As of right now if there are no errors on the TFT display it connects to the ECU just fine. Once the errors on the TFT display start popping up it loses connection to the ecu. Some times it take it a minute before the trans fault, tcs disabled and check engine warnings come up on the display. for quick stuff I use the OBDlink app they have. It loads up way quicker then the TuneECU which I also use.
 
Been a busy month since I last posted. Haven’t had a chance to do anything on the Rocket. I decided to get married, took a vacation, and now I’m in the middle of moving.

Got the bike started the other day just to load it onto a trailer, and I was able to get my BT dongle connected to read the error codes. Took a screenshot (attached below) and was quick enough this time. First step will be checking for loose wires like everyone’s suggested. Almost done moving, supposed to wrap it up tomorrow so hopefully I can really dig into it next weekend.

Edit: Got tuneecu to work and it had those 3 plus a p16a1 code

Thanks appreciate it.

Took the battery in and it was bad. Put the new one in and still happening same 4 error codes, and it runs through the random TCS disabled, check engine, transmission fault quickly to the point you almost can't read them. Also fuel gauge isn't reading any fuel in the tank. Was hoping the new battery was the issue. Knew I wouldn't be that lucky lol.

I did and the codes did not come back. Still have no fuel gauge it's just blank. And as I was backing the bike out while running the ocabs disabled came on which was what happened when my cruise control stopped working (it showed it so fast that time I didn't catch what it said). Along with transmission fault, TCS disabled warnings flashing across the display in quick order before stopping. The gear indication also only showed a dash mark as well rather then it saying Neutral and bike won't turn on once again, once I shut it off. I've attached a pic of the display.
