haven’t used my bike in quite some time. Started up last night no check engine light. Drove a few miles got check engine light and threw a “45” code. Bike has bench side flash tune and autoblipper. Tried disconnecting the battery but still the issue remains.

Hello,
I would start with checking the battery and starter solenoid terminals for being loose as well the fuses.

Fault code 45: POWER SHUT OFF: INCORRECT BACK UP VOLTAGE IS SUPPLIED TO ECU
1st step is to check battery leads to see if any are loose.
If that doesn't work, check the starter relay coupler, check the back up fuse condition. Finally check wire harness continuity. If nothing else, you have a bad ECU.
