What does TAS2-A211 mean?
Tesla alert code in the Thermal Architecture System v2 (TAS2) module. This alert indicates that the air suspension controller does not have stored ride height calibration. This is expected for a "virgin" board but should not be seen after the suspension ride height has been successfully calibrated. The alert checks for height sensor calibration status once per second. Set: If height sensor calibration values are unavailable in memory, the alert is set. Clear: If height sensor calibration values become available in memory, the alert is cleared.
