I went to start my bike the other day after it had been sitting for months. Battery was low and when I eng the starter all the lights started flashing rapidly. The bus error message came up and then nothing. I located a used turn signal module. Replaced it. Bike starts now but still has bus error. The tach and speedo no longer work either. I tried checking codes but I get “no rsp” now. I’m assuming there was a voltage spike and took out the IM as well. Is there anything else I should be looking for?
