EEPROM FAULT Error in reading EEPROM locations
HPD High pedal disable (HPD) fault
HW FAILSAFE Motor voltage fault
LOW BATTERY VOLTAGE Battery voltage too low
MAIN CONT FLTS Main contactor did not close or did not open
MAIN ON FAULT Main contactor driver failed short
MAIN OFF FAULT Main contactor driver failed open
NO KNOWN FAULTS No known faults
OVERVOLTAGE Battery voltage too high
POWER SECTION FAULT MOSFET driver fault, or shorted motor wiring
PRECHARGE FAULT Capacitor bank voltage < minimum operating voltage
PROC/WIRING FAULT
