VCBATT_a231_12VTempSensShort

The vehicle controller is reporting a short circuit on the low voltage (LV) battery temperature sensor, indicating damage to the sensor or wiring harness.

Live incidence rate

<0.01% (Extremely rare)

Vehicle messages

None displayed

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.

Description

Cause

The LV battery temperature sensor circuit reads a power rail reference voltage, indicating a short circuit.

Clear condition

The LV battery temperature sensor circuit no longer reads a power rail reference voltage.
