Why does the exact Tesla alert ID matter?
Record the exact alert ID, including underscores, suffixes, and companion alerts. Tesla alerts that look similar can point to different modules, timestamps, and service procedures.
What does TAS-A225 mean?
Tesla alert code in the Thermal Architecture System (TAS) module. Gallery pressure was measured to be higher than expected under any operating condition. Front axle has been measured to be lower than any reasonable height. Front axle has been measured to be lower than any reasonable height for an extended period. Front axle has been measured to be not be lower than any reasonable height for an extended period. Debug information for 100ms task errors. Set along with TaskSchedulerError. Front right air valve detected short circuit. Front right air valve output shorted to ground or battery voltage. One or more CAN messages from GTW are not being received by the ECU. One or more CAN messages from GTW are not being received by the ECU (missing, bad RX rate, or invalid checksum/counter). Successful reception of all RXd CAN messages from GTW. Air suspension functionality may be reduced. Air suspension may not be able to recover from corrected faults. Debug information for 1000ms task errors. Set along with TaskSchedulerError. Rear right air valve detected open circuit. Rear right air valve commanded on but no electrical current measured. Front left air valve has reached its duty cycle (on time) limit. Front left air valve has dropped below its duty cycle (on time) limit, plus some hysteresis. Air suspension leveling will be temporarily disabled until front left air valve duty cycle drops.

Affected Tesla Models
What You May Notice
- Thermal Architecture System alert: Gallery pressure was measured to be higher than expected under any operating condition. Front axle has been measured to
- Reduced charging speed in cold weather or battery pre-conditioning required
- HVAC performance may be slightly affected
How to Diagnose and Resolve
- 1 Reboot the vehicle
- 2 Check coolant levels if accessible (Model S/X only)
- 3 Avoid DC fast charging until battery temperature normalizes
- 4 Schedule service if the alert appears in warm ambient conditions
Severity Notes
TAS-A225 is an Alert in the Thermal Architecture System system. Confirm the vehicle screen and Tesla app show no driving or charging restrictions, and schedule service if the alert returns.
