The vehicle controller is reporting an open 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

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

Cause

The LV battery temperature sensor circuit reads a ground reference voltage, indicating an open circuit (disconnected).

Clear condition

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