Not Available

What does the HVP_w068_shuntUnexpectedThermistor alert mean?

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.

What you'll see in your Tesla

  • Not Available

What triggers it

A shunt thermistor is detected when the shunt TCRs in the HVP calibration block indicate a shunt thermistor should not be present.

When it clears

The shunt TCRs programmed into the HVP calibration block indicate the shunt should have a thermistor.

Potential impact

The High Voltage Controller (HVC) will measure the pack current less accurately affecting algorithms such as pack energy estimation. No immediate vehicle functional impact.

Affected models

Model 3 2017-2023 Model 3 2024+ Model S 2021+ Model X 2021+ Model Y Model Y 2025+
