Check engline 2012 prius p0aa6

Hello I have a Toyota prius 2012 lll 200,000 miles to it.
Yesterday check engine and check hybrid system appeared and diagnostics showed this:
1. P0A0F - Engine failed to start.
2. P0AA6 - Hybrid battery voltage system isolation fault
3. P314A - Inverter coolant pump speed signal.
4. U0100 - Lost communication with ECM/PCM "A".

When this happened heat inside was on the maximum. When I press accelerator it speeds up but doesn't have a big reaction. After some time red steering wheel appeared and car went to neutral. Please help me.
