Description
The low voltage (LV) battery is no longer supported by the power conversion system (PCS). The vehicle low voltage electrical system needs to shed electrical loads by cutting power to some systems / electronic control units (ECUs).
Condition
Lead acid: low voltage (LV) battery voltage below 12.2V while high voltage (HV) support from the power conversion system (PCS) is requested; Li-ion: low voltage (LV) battery is not supported by the power conversion system (PCS), or the vehicle has experienced a crash event
Clear Condition
Lead acid: low voltage (LV) battery voltage above 12.9V and high voltage (HV) state is up; Li-ion: low voltage (LV) battery is supported by the power conversion system (PCS) or, in the case of a crash, the Unified Diagnostic Services (UDS) routine is run successfully
Potential Impact
Lead acid: Convenience features such as seat heaters, auxiliary ports, and HVAC will no longer be available. Li-ion: All nonessential features / components will no longer be available, with support reserved for critical functions like operating doors, windows, exterior lights, and front trunk (frunk).
