TAS2-A033
TAS2_a033_PWMerrorRR
What does TAS2-A033 mean?
Tesla alert code in the Thermal Architecture System v2 (TAS2) module. The alert checks for height sensor PWM faults every 10ms. A weighted counter increments by 10 for every repeated fault and triggers the fault at a threshold of 50. The weighted counter decrements by 1 for every valid reading and clears the fault when it reaches 0. TAS2_a033_PWMerrorFL will trigger if any of the following faults are set: PWM_OVER_MAX_DUTY -Set:The height sensor PWM signal has had a duty cycle greater than 87.5% for 50ms. -Clear:The height sensor PWM signal has had a duty cycle less than 87.5% for 500ms. PWM_UNDER_MIN_DUTY -Set: The height sensor PWM signal has had a duty cycle less than 12.5% for 50ms. -Clear:The height sensor PWM signal has had a duty cycle greater than 12.5% for 500ms. PWM_OVER_MAX_PERIOD -Set: The height sensor PWM signal has had a period greater than 0.00131579 seconds for 50ms. -Clear:The height sensor PWM signal has had a period less than 0.00131579 seconds for 500ms. PWM_UNDER_MIN_PERIOD -Set: The height sensor PWM signal has had a period less than 0.00119048 seconds for 50ms. -Clear:The height sensor PWM signal has had a period greater than 0.00119048 seconds for 500ms. PWM_OVER_MAX_DELTA_DUTY (cannot be set if transitioning to/from 0 or 100% duty cycle) -Set: The height sensor PWM duty cycle has changed by more than 33% (3.3 * 10ms alert period) since its previous cycle for 50ms. -Clear: The height sensor PWM duty cycle has changed by less than 33% (3.3 * 10ms alert period) since its previous cycle for 500ms.
Original Description
The alert checks for height sensor PWM faults every 10ms. A weighted counter increments by 10 for every repeated fault and triggers the fault at a threshold of 50. The weighted counter decrements by 1 for every valid reading and clears the fault when it reaches 0. TAS2_a033_PWMerrorFL will trigger if any of the following faults are set: PWM_OVER_MAX_DUTY -Set:The height sensor PWM signal has had a duty cycle greater than 87.5% for 50ms. -Clear:The height sensor PWM signal has had a duty cycle less than 87.5% for 500ms. PWM_UNDER_MIN_DUTY -Set: The height sensor PWM signal has had a duty cycle less than 12.5% for 50ms. -Clear:The height sensor PWM signal has had a duty cycle greater than 12.5% for 500ms. PWM_OVER_MAX_PERIOD -Set: The height sensor PWM signal has had a period greater than 0.00131579 seconds for 50ms. -Clear:The height sensor PWM signal has had a period less than 0.00131579 seconds for 500ms. PWM_UNDER_MIN_PERIOD -Set: The height sensor PWM signal has had a period less than 0.00119048 seconds for 50ms. -Clear:The height sensor PWM signal has had a period greater than 0.00119048 seconds for 500ms. PWM_OVER_MAX_DELTA_DUTY (cannot be set if transitioning to/from 0 or 100% duty cycle) -Set: The height sensor PWM duty cycle has changed by more than 33% (3.3 * 10ms alert period) since its previous cycle for 50ms. -Clear: The height sensor PWM duty cycle has changed by less than 33% (3.3 * 10ms alert period) since its previous cycle for 500ms.
Severity Notes
TAS2-A033 is an Alert in the Thermal Architecture System v2 system. It is generally safe to continue driving, but have it checked at your next scheduled service.
