2012 GTX 155 screen wont turn off and Ibr error.

[sdriche]

I have a 2012 GTX 155 which had a problem last year where the screen wouldn’t turn off and the ski would only start sometimes after wake up. I replaced the DESS post last year and that seemed to fix the issues. Fast fwd this year , took the ski out, no problems for about an hour of riding, then went into limp mode with an ibr error. Reset the. Check engine light (holding set while powering on) and it ran great for another 20 mins and repeated the limp mode. Now the screen stays on alll the time. Pulled the 30 amp fuse, reset, and as soon as you reinsert the fuse it wakes up and beeps as if the key were on it, won’t start. I disconnected the DESS wires and no change…stays on. Thoughts on next steps/ or cause? Thanks,
