Why is my 2013 honda civic imid not working?

When You say that the 2013 Honda Civic's iMID screen isn't working, my first question is to ask if You've recently jumped Your vehicle. The iMID has a safety feature such that when You've recently jumped it, it'll actually go into something called "protect mode". It should just come back on its own after a few restarts, in this case. Though, if You're searching the internet on this, I'm guessing You've already went through that. So, You've got three likely scenarios here. The first is that the fuse has blown: to check, You're going to need to access the under-the-hood fuse boxAnd check fuse the 10a fuse, A29. If that's blown, well, that's at least part of Your problem. Next, You're going to want to see if it's a stored software setting. To find out, do a battery cable reset (someone asked how to do that in another question here, so go refer to that if need be) and see if that clears it up. If neither of those two avenues sort it, it's quite possible the information display itself has failed, in which case, hopefully it's still under warranty, else You'll likely want to explore some of the aftermarket solutions.
