What does TAS-A290 mean?

Tesla alert code in the Thermal Architecture System (TAS) module. Ride height sensors are measured to be in twisted or implausible state. Implausible condition detected on rear right air valve circuit, possibly due to ECU hardware failure. Implausible condition detected on front left air valve circuit. Air compressor has reached its duty cycle (on time) limit. Air compressor has dropped below its duty cycle (on time) limit, plus some hysteresis. Air suspension leveling via the air compressor will be temporarily disabled until air compressor duty cycle drops. Abnormal PWM signal received from front right PWM height sensor. More sensitive than other ride height sensor alerts. Implausible condition detected on air compressor or air compressor relay circuit, possibly due to ECU hardware failure. Implausible condition detected on front right air valve circuit. Implausible condition detected on front right air valve circuit, possibly due to ECU hardware failure. Air suspension system is operating under limp home mode 20 restrictions. The ECU has detected an issue whose severity requires operating under limp home mode 20 restrictions.

Severity Notes

TAS-A290 is an Alert in the Thermal Architecture System system. It is generally safe to continue driving, but have it checked at your next scheduled service.
