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-A285 mean?
Tesla alert code in the Thermal Architecture System (TAS) module. Ride height sensors are measured to be in twisted or implausible state. Customer facing version of the alert. Ride height sensors are measured to be in twisted or implausible state while vehicle is driving. Ride height sensors are not measured to be in twisted or implausible state. An airline to the air springs or air reservoir has been detected blocked/crushed. An airline to the air springs or air reservoir has been detected blocked/crushed, detected via a higher than expected increase in pressure when filling using compressor. A watchdog (external or internal) was not serviced in time. Suspension controls may not continually work as intended.

Affected Tesla Models
What You May Notice
- Thermal Architecture System alert: Ride height sensors are measured to be in twisted or implausible state. Customer facing version of the alert. Ride heigh
- 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-A285 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.
