Signal Name Description Condition Impact Important
UMC input terminals (UMC side of smart adapter connection) exceeded temperature threshold
UMC input terminal temperature has exceeded 95 C
UMC will not allow charging until input terminals cool sufficiently
No
UMC vehicle connector exceeded temperature threshold
UMC vehicle connector (charge handle) temperature has risen above 75 C
UMC will not allow charging until the charge handle cools sufficiently
No
UMC wall plug (smart adapter) exceeded temperature threshold
UMC smart adapter temperature exceeded 75 C or the smart adapter specific rating if present
UMC will not allow charging until the smart adapter temperature has fallen sufficiently
No
UMC PCB temperature exceeded threshold
UMC PCB temperature exceeded 100 C
UMC will not allow charging until the PCB cools off sufficiently
No
UMC detected contactor stuck open or closed
UMC contactor is open when it should be closed (non-EU smart adapter) or closed when it should be open for several seconds
UMC will not allow charging if the contactor is stuck in an unexpected state. Charge handle pins may be live and hazardous. Stuck open (non-hazardous) contactors will not trigger this fault with EU smart adapters.
No
UMC AC input voltage is below lower limit
UMC AC input voltage has fallen below 90 V RMS
UMC will not allow charging until AC input voltage is within 90-300 V RMS
No
UMC AC input voltage exceeded upper limit
UMC input voltage has risen above 300 V RMS
UMC will not allow charging until AC input voltage is within 90-300 V RMS
No
UMC GFCI self test failed
GFCI self test failed
UMC will not charge until the self test passes. UMC will retest automatically after 15 minutes (except EU smart adapters) or charge cable cycle
No
UMC ground leakage current exceeded threshold
A ground fault current exceeding detection threshold was detected
UMC will not charge until the ground fault is corrected. UMC will retest after 15 minutes (except when an EU smart adapters) or charge cable cycle
No
UMC AC input side ground impedance exceeded threshold
UMC AC input side ground impedance is above 1 Mohm
UMC will not allow charging until the protective earth connection is corrected
No
Infotainment GPU operation timed out
GPU driver reports a fence timeout
Touchscreen or UI may not be responsive
No
Infotainment process hung for extended period of time
Operating System reports a task was hung for 2 minutes
Touchscreen or UI may not be responsive
No
A phone contact sync with more than 5000 contacts completed. Alert payload contains the number of contacts loaded.
This alert is set when a phone is connected to Bluetooth and a phone contact is synced with over five thousand contacts.
Bluetooth connection and call quality may be impacted during a large phone contact sync. Normal operation is expected after the sync is completed.
No
The Media Control Unit (MCU) does not detect a connection to the center display.
The MCU's DisplayController does not detect a display present at the center display connector.
The center display may not be powered or may not function as expected.
No
Indicates that the User Interface (UI) main application, also known as QtCar, is intentionally rebooting due to a user-initiated action.
QtCar receives a valid request to reboot, such as a user-initiated software update or a settings change that requires a restart.
QtCar will temporarily be unavailable during reboot, which may cause a brief interruption to the user's interaction with the vehicle's systems.
No
The Media Control Unit (MCU) does not detect a connection to the rear display.
The MCU's DisplayController does not detect a display present at the rear display connector.
The rear display may not be powered or may not function as expected.
No
Summon not available, vehicle not on private property
Map data for current GPS position suggest that the vehicle is not on private property, considering road class and distance to the nearest road
Summon unavailable
No
Driver Drowsiness and Attention Warning (DDAW) system is not operating as expected.
DDAW feature is enabled in the vehicle's region and experienced a condition affecting its operation. Investigate any alerts from the Autopilot (AP) system for possible causes.
DDAW active safety feature is unavailable.
No
Modem failing to power ON
Successive modem power ON failures
Loss of cellular connectivity
No
Alert set remotely by Tesla
Alert set remotely by Tesla
Service required
No
