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.

There may be a decrease in available energy to the vehicle, reducing range and LV support.
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.
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.
The bleed test reports sufficient voltage change across each brick.
