HVBATT_a743_BleedFetFailure
Description
A bleed Field-Effect Transistor (FET) on the Battery Management Board (BMB) is not operating as designed. This will prevent the battery from balancing the brick by decreasing the brick voltage.
Condition
Upon a periodic wake, after an ECU reset, or every 6 hours, the Battery Management System (BMS) will test all bleed switches by switching them on in turn. If the sensed brick voltage does not significantly change, this alert is set.
Clear Condition
The bleed test reports sufficient voltage change across each brick.
Potential Impact
There may be a decrease in available energy to the vehicle, reducing range and LV support.
