What does TAS2-A143 mean?

Tesla alert code in the Thermal Architecture System v2 (TAS2) module. This alert checks for short circuit faults every 10ms. Voltage and current are measured by the Tesla Air Suspension Controller (TASC) when the boost valve is commanded with 12V. Set: The boost valve is commanded and both of the following are true: voltage is sensed below 2.4Vcurrent is sensed below 0.02A or above 1.3AClear: Single drive-rail cycle
