TAS2-A298
TAS2_a298_vinNotLearned
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.
