VCLEFT_a533 — T LVBMS Mosfet Over Temperature Fault
Full alert identifier: VCLEFT_a533_TLVBMS_MosfetOverTemperatureFault
Alert description
The Low Voltage (LV) battery internal protection transistor (MOSFET) temperature is greater than the temperature limit.
Potential impact
There may be a loss of LV battery pack power. This alert may indicate a high impedance or other conditions affecting the expected operation of the LV battery MOSFET.
Set condition
The MOSFET temperature is greater than the expected set temperature limit for longer than expected.
Clear condition
The MOSFET temperature is within the expected temperature threshold.
