The battery management system (BMS) detects an issue with the high voltage interlock loop (HVIL). The voltage at the HVIL output pin of the BMS is too low (in respect to the number of HVIL nodes the vehicle has) or too close to the HVIL open voltage.
<0.01% (Extremely rare)

Inability to charge, drive, or support the low voltage (LV) system
The battery management system (BMS) detects an issue with the high voltage interlock loop (HVIL). The voltage at the HVIL output pin of the BMS is too low (in respect to the number of HVIL nodes the vehicle has) or too close to the HVIL open voltage.
HVIL output voltage sensed by the BMS is outside of the expected bounds.
The BMS detects that the condition clears.
