BMS_w036 — SW HVIL
Full alert identifier: BMS_w036_SW_HVIL
Alert description
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.
Potential impact
Inability to charge, drive, or support the low voltage (LV) system
Set condition
HVIL output voltage sensed by the BMS is outside of the expected bounds.
Clear condition
The BMS detects that the condition clears.
