BMS_w054_SW_Current_Sensor
Vehicle may not restart
What does the BMS_w054_SW_Current_Sensor alert mean?
The battery management system (BMS) detects an issue with the high voltage (HV) internal current sensor.
What you'll see in your Tesla
- Vehicle may not restart
- Service is required
What triggers it
The measured current is sufficiently far from zero with contactors open, the current sensor is reporting the same current for too many samples in a row, or the current sensor is behaving irrationally (for example, it is dropping packets).
When it clears

Potential impact
Inability to charge, drive, or support the low voltage (LV) system
