TAS2-A290
TAS2_a290_twistSustainedAtSpeed
What does TAS2-A290 mean?
Tesla alert code in the Thermal Architecture System v2 (TAS2) module. This alert checks for twistSustainedAtSpeed faults every 100ms. Twist indicates that two diagonal corners are higher than the other two and the chassis is reporting a twisted state - as if one wheel was parked on a large block. At speed, twist should not be observed because no road surface can hold the vehicle in a twisted state while in motion. Twist is calculated using the four corner heights: front right (FR), front left (FL), rear right (RR), and rear left (RL). Twist = | (FL+RR)-(FR+RL) | Set: When vehicle speed is greater 10mph AND twist is greater than 20mm for 10 seconds. Clear: When vehicle speed is less than 10mph OR twist is less than 20mm.
