The High Voltage Processor (HVP) detects the shunt thermistor is present when the HVP calibration block has shunt Temperature Coefficients of Resistance (TCRs) for a shunt without a thermistor.

The High Voltage Controller (HVC) will measure the pack current less accurately affecting algorithms such as pack energy estimation. No immediate vehicle functional impact.
The High Voltage Processor (HVP) detects the shunt thermistor is present when the HVP calibration block has shunt Temperature Coefficients of Resistance (TCRs) for a shunt without a thermistor.
A shunt thermistor is detected when the shunt TCRs in the HVP calibration block indicate a shunt thermistor should not be present.
The shunt TCRs programmed into the HVP calibration block indicate the shunt should have a thermistor.
