This alert is usually specific to external charging equipment and power sources and does not typically indicate an
issue with your vehicle that can be resolved by scheduling service.
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

convenience.
UI_a137
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

The vehicle cannot charge because the ground-fault circuit interrupter (GFCI) in the Mobile Connector has tripped.
Like the GFCI in a wall outlet, this feature is designed to stop the flow of electricity when there is a problem. It has
interrupted charging to protect your vehicle and the charging equipment.
This could happen for many reasons. The problem could be in the charge cable, the charge handle, the charge port,
or even an onboard vehicle component.
What to do:
Inspect the charge port and the charge handle for pooled water or unusual levels of moisture. If you find excessive
moisture, wait and let both the inside area of the charge port and the exposed portion of the charge handle dry
sufficiently before trying again.
Inspect the charge equipment for damage.

Unable to charge with Mobile Connector
Voltage too low / Try a different wall outlet
What this alert means:
The vehicle cannot charge, or charging is interrupted, because either the Mobile Connector:

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.
A warm outlet may be caused by a plug that is not fully inserted, a loose building wiring connection to the outlet, or
an outlet that is beginning to wear out.
What to do:
Make sure your adapter is fully plugged into the outlet. If charging speed does not return to normal, contact an
electrician to inspect the outlet and building wiring connections to the outlet and complete any repairs needed.
If the outlet is worn, it should be replaced with a high-quality outlet. Consider upgrading to a Tesla Wall Connector
for greater convenience and highest charging speed.
UMC_a009
Cannot charge - Charge handle temperature high
Check charge handle or charge port for debris
What this alert means:
Charging has been interrupted because the Mobile Connector has detected a high temperature in the charge handle
that connects to your vehicle
Page 271 of 298
After unplugging from the power source (wall outlet), inspect the wall plug adapter connection and the Mobile
Connector control box connection for any obstructions or moisture. Make sure any obstruction has been removed
and any moisture has been allowed to dry, then try re-inserting the wall plug adapter into the Mobile Connector and
then connecting to the power source (wall outlet).
Once the Mobile Connector control box temperature has decreased and any obstruction has been removed, the alert
should clear and charging should possible.
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

First, confirm the lack of effective communication is caused by the Mobile Connector rather than an issue with your
vehicle. This is usually the case.
To confirm this, try charging the vehicle using different external charging equipment.
