What does TAS2-A227 mean?
Tesla alert code in the Thermal Architecture System v2 (TAS2) module. Alert is set to indicate that the front right (FR) height sensor temporarily faulted when 100%, 0%, or a large delta in the duty cycle was read from the front left (FL) pulse width modulation (PWM) height-sensor. Duty cycle of 100% indicates an open circuit. Duty cycle of 0% indicates a short to ground. The alert will clear when one second of expected values is received from the FL height-sensor.
