What you'll see in your Tesla
- Not Available
What triggers it
The LV battery temperature sensor circuit reads a power rail reference voltage, indicating a short circuit.
When it clears
The LV battery temperature sensor circuit no longer reads a power rail reference voltage.
Potential impact
A default voltage setpoint is used when charging the LV battery, instead of optimizing the voltage setpoint based on the LV battery's actual temperature. The LV battery may experience accelerated degradation if this continues.
