Hello and welcome to JustAnswer!

There are quite a few things that could be going on and it will require some electrical testing to determine exactly what is wrong. The problem could be as simple as a dead battery, you could have a wiring or power distribution issue, an internal failure in a module, it may be a bus communication issue.

Are you hoping to do the required electrical testing yourself?
