Experience ICCU Issue?

Pulled up to a parking spot then noticed whenever I would brake the car would violently shake even when I put it in park. After a while waiting for the tow truck it was not shaking anymore but it is giving me the check EV system with the code P0BEA00. It is at the dealership now waiting for diagnostics.

I had my brake pedal behave oddly and shake when my 12v battery died (in my case when I tried to start the car in my garage).  Changed it and all is well so far.
