Control: Master

Troubleshooting:
- This fault signals that the under voltage/over voltage protection interrupt has been triggered.
- A real under voltage/over voltage key input (C3) happened. Voltage has been below 16V
- A real over voltage on the power capacitors happened, voltage has been 63V.
- Fault in the hardware section of the logic board that manages the over voltage protection.
- Possible plugging in or unplugging of battery or charger with the key switch on.
