Active service connection to vehicle
Service performing remote diagnostics
What this alert means:
A service technician is remotely logged into your vehicle for diagnosis or repair. You may notice some loss of Infotainment
functionality while the connection persists, but this alert does not indicate an issue with your vehicle.
Your vehicle is OK to drive.
What to do:
This alert should clear automatically after the technician completes vehicle diagnosis or repair. You may find it necessary to
restart your touchscreen to restore full Infotainment functionality after the alert has cleared. For more information, see
Restarting the Touchscreen in your vehicle's Do It Yourself Guide.
If this alert does not clear after 24 hours, it is recommended that you schedule service via your Tesla Mobile App or with an
independent service provider. Please note that independent service provider options may vary, based on your vehicle
configuration and your location.
UMC_a001
Unable to charge with Mobile Connector
Inadequate outlet grounding - Try another outlet
What this alert means:
The Mobile Connector has detected that the electrical outlet has insufficient grounding, likely caused by an inadequate or
missing ground connection.
This does not indicate an issue with your Mobile Connector or vehicle, but instead points to an issue with the wall outlet /
electrical installation the Mobile Connector is connected to.
What to do:
Have the electrical installation inspected by an electrician. Your electrician should make sure there is proper grounding at your
circuit breaker or power distribution box, and also make sure that appropriate connections are made to the outlet, before you
attempt to plug in the Mobile Connector again.
If you need to charge in the meantime, try charging using a different outlet, at another location, or with another type of
charging station.
You can also try charging your vehicle using a Tesla Supercharger or Destination Charging location, all of which can be located
through the map on your vehicle's touchscreen display. See Maps and Navigation on page 144 for more details.
For more information on troubleshooting Mobile Connector status lights and charging issues, refer to the product's owner's
manual.
