ck engine,no ps,no speedo display?

I did search and didn’t find anything like this. I was riding today and my check engine came on and the power stearing light as well, no power steering. That’s pretty common from what I read but here’s where it gets a little strange to me. The info center in the speedo also quit working. Nothing, no rpm’s,no temp,no voltage reading nothing. Also about 5 minutes after that my bully dog started saying initializing communication but could never complete the comunication. I turned it off on back on several times but still the same issue and actually the bully dog wouldn’t even come on a few of those times. I’m think voltage regulated as I know this is a common problem but the info center isn’t working for me to check the voltage. Any ideas?
