Set: An open circuit, short circuit, or unexpected resistance value is detected on the valve after startup, or if the damper current deviates from the commanded current over time (indicating an unexpected circuit behavior). Clear: Drive rail cycle or ECU power cycle.

Tesla alert code in the Thermal Architecture System v2 (TAS2) module. This alert is set each time the Tesla Air Suspension (TAS) board is set to Jack mode or wakes while in Jack mode (Chassis bus turns on).

Tesla alert code in the Thermal Architecture System v2 (TAS2) module. This alert is a load-shed request from Gateway (GTW) due to the voltage of the LV bus. Set: This alert is set when the GTW sends the CH_hvBatteryLow signal, which is a carry-over signal from Electronic Air Suspension (EAS). Despite the name of the alert, this message indicates to the air suspension controller that the LV system (not necessarily the LV battery or HV battery) is at a low voltage, and so it sends the controller into a limp mode to reduce the electrical loading on the LV system. It is likely to see this during a load-shed event where the LV system is not being properly supported by the DCDC. Clear: Clearing of the low high-voltage battery signal (CH_hvBatteryLow).

Tesla alert code in the Thermal Architecture System v2 (TAS2) module. This alert indicates that the ride height sensor positions are in an unexpected range compared to a known default value, which is determined in firmware. It is meant to catch gross miscalibrations. This alert and yellow warning lamp indicate that the calibration on at least one corner is between 25 and 50mm away from the default. If (during ride height calibration) the operator enters a height measurement that results in an offset that is 25-50mm from the default offset, the calibration will be accepted but will cause the aforementioned alert to be set, with a yellow warning lamp. Operation will not be restricted.If the operator enters a height measurement that results in an offset that is more than +/-50mm from the default offset, the Unified Diagnostic Services (UDS) routine will fail and nothing will change. No alert will appear and no calibration information will be saved.Each vehicle will have the ride height sensor in a slightly different position due to tolerance stackup. This is why Tesla Air Suspension (TAS) allows for a +/-25mm window before setting the alert.

Tesla alert code in the Thermal Architecture System v2 (TAS2) module. This alert indicates that the air suspension controller does not have stored ride height calibration. This is expected for a "virgin" board but should not be seen after the suspension ride height has been successfully calibrated. The alert checks for height sensor calibration status once per second. Set: If height sensor calibration values are unavailable in memory, the alert is set. Clear: If height sensor calibration values become available in memory, the alert is cleared.

Tesla alert code in the Thermal Architecture System v2 (TAS2) module. The alert checks for exhaust gallery faults every 100ms. Set: After an exhaust procedure, gallery pressure stays above 5 Bar. Clear: After an exhaust procedure, gallery pressure decreases below 5 Bar. Note: An exhaust procedure is considered completed if one of the following is true: After opening the exhaust valve, gallery pressure has been constant within +/- 0.05 Bar for 50ms.The exhaust valve has been open for more than 2.5 seconds.The gallery is the volume within the valve block that gets pressurized prior to filling the reservoir or an air spring. The gallery is where the pressure sensor measures pressure when other components open their valves to connect to the gallery. The gallery is exhausted to atmosphere after a filling or a pressure check operation to reduce stress on the system. This is done by closing all valves except the exhaust valve, allowing the gallery pressure to decrease. The decrease in gallery pressure is limited by an internal check valve in the compressor, which is rated above atmospheric pressure.

Tesla alert code in the Thermal Architecture System v2 (TAS2) module. This alert indicates that the gallery (the shared air volume within the valve block) is observing an increasing pressure reading with all valves commanded closed.

Tesla alert code in the Thermal Architecture System v2 (TAS2) module. The alert checks for compressor prefill faults every 100ms. Set: Compressor prefill will timeout during a prefill operation if the pressure derivative remains under 1 bar/second for 10 seconds. Clear: Single drive-rail cycle Note: A prefill operation is performed before opening the valves to an air spring or the reservoir. Prefill works by activating the compressor with the spring and reservoir valves closed, so that the gallery pressure increases. This reduces the change in pressure upon opening of the valves, similar to the precharge sequence for the high-voltage battery or on-board chargers. Prefill will fail if: a valve is open or leaking (pressure escapes from the gallery) the compressor does not run compressed air escapes before the valve block

Tesla alert code in the Thermal Architecture System v2 (TAS2) module. The alert checks for blocked airline faults every 100ms. Set: The pressure derivative exceeds 4 Bar/s for 1 second and Tesla Air Suspension (TAS) is in one of the following states: TAS_state = Fill_reservoir_from_Compressor TAS_state = Fill_spring_reservoir_from_Compressor TAS_state = Fill_spring_from_Compressor TAS_state = Fill_spring_from_Boost Clear: Single drive-rail cycle When the system is functioning normally, the gallery pressure should not climb this fast while filling a spring or the reservoir.

Tesla alert code in the Thermal Architecture System v2 (TAS2) module. The alert checks for blocked airline faults every 100ms. Set: The pressure derivative is less than 0.1 Bar/second for 10 seconds 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 When the system is functioning normally, the gallery pressure should rise faster than this while filling a spring or the reservoir.

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.

Tesla alert code in the Thermal Architecture System v2 (TAS2) module. Alert is set to indicate that the front right (FR) height sensor temporarily faulted when 100%, 0%, or a large delta in the duty cycle was read from the front left (FL) pulse width modulation (PWM) height-sensor. Duty cycle of 100% indicates an open circuit. Duty cycle of 0% indicates a short to ground. The alert will clear when one second of expected values is received from the FL height-sensor.

Tesla alert code in the Thermal Architecture System v2 (TAS2) module. Alert is set to indicate that the rear right (RR) height sensor temporarily faulted when 100%, 0%, or a large delta in duty cycle was read from the RR pulse width modulation (PWM) height-sensor. Duty cycle of 100% indicates an open circuit. Duty cycle of 0% indicates a short to ground. The alert will clear when one second of expected values is received from the RR height-sensor.

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.

Tesla alert code in the Thermal Architecture System v2 (TAS2) module. This alert checks for targetHeightNotMet faults every 100ms.

Tesla alert code in the Thermal Architecture System v2 (TAS2) module. Tesla Air Suspension 2 (TAS2) uses a common PCBA/Hardware ID for Model S and Model X, but uses different software applications (.hex files / configs) between the two vehicle types. If this alert is active, the chassis type of the firmware on the controller does not match the chassis type received on a car area network (CAN). Damping control will enter a backup state and endstop protection will not be active. Set: GTW_chassisType does not match the internal chassisType of the firmware on the controller. Clear: GTW_chassisType matches the internal chassisType of the firmware on the controller.

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. The VIN learned to the controller does not match the VIN received on a car area network (CAN). Learned endstops may be incorrect. Damping control will enter a backup state and endstop protection will not be active. Set: The VIN learned to the controller does not match the VIN received on CAN. Clear: A VIN is saved by performing ride height calibration. Note: If using the normal air suspension calibration panel in TBX2 clears TAS2_a297_vinMismatch, perform another calibration using the "Air Suspension Calibration (Advanced)" Panel.

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.
