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 TAS2-A225 mean?
Tesla alert code in the Thermal Architecture System v2 (TAS2) module. The alert checks for high gallery pressure faults every 100ms. Set: Gallery pressure is greater than 19 bar for 1 second and Tesla Air Suspension (TAS) is in one of the following states: TAS_state = Fill_reservoir_from_CompressorTAS_state = Fill_spring_reservoir_from_CompressorTAS_state = Fill_spring_from_CompressorTAS_state = Fill_spring_from_Boost Clear: Single drive-rail cycle This indicates that the gallery pressure (where the pressure sensor is located) is over 19 bar, and has stayed at over 19 bar for one second. The system pressure for TAS is 18 bar, so while the system is functioning normally, pressure should never be over 19 bar, especially for over one second.
