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-A298 mean?
Tesla alert code in the Thermal Architecture System v2 (TAS2) module. Tesla Air Suspension 2 (TAS2) uses a VIN learn because the system learns the damper travel endstops to compensate for any differences between height calibrations and nonlinearity between vehicles. A VIN has not been saved to the controller. Damping control will enter a backup state and endstop protection will not be active. This is expected for a new ECU that has just been installed into a vehicle, or on a vehicle where the ride height calibration has been cleared. Set: The VIN learned to the controller does not match the VIN received on a car area network (CAN). Clear: A VIN is saved by performing ride height calibration.
