Troubleshooting Alerts
Your vehicle's onboard charger has detected that one or more power converters is not receiving the necessary AC
input voltage. For example: during three-phase charging, one phase might be missing from the AC input power
provided by the external source. This could occur due to a condition affecting the external charging equipment, the
power source it is connected to, or your vehicle itself.
As this alert is usually specific to external charging equipment and power sources, and it does not typically indicate
an issue with your vehicle that can be resolved by scheduling service, it is recommended that you try charging with
multiple, different types of charging equipment.
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 136 for more
details. Additional third-party charging stations may also be available in your area to help you to pinpoint the issue.
For more information on troubleshooting Mobile Connector or Wall Connector status lights, refer to the product's
Owner's Manual at Charging & Adapter Product Guides. If using other external charging equipment, refer to the
manufacturer's provided documentation for troubleshooting tips.

Active service connection to vehicle
Service performing remote diagnostics
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.
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.

Unable to charge with Mobile Connector
Inadequate outlet grounding - Try another outlet
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.
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.
