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

Mobile Connector to adapter connection hot
Let cool - Plug adapter fully into Mobile Connector
What this alert means:
Charging has been interrupted because the Mobile Connector has detected a high temperature at the connection
between the wall plug adapter and the control box.
What to do:
Make sure the wall plug adapter is fully connected to the Mobile Connector control box.
Also make sure the wall plug adapter is not covered by anything, and that there is no heat source nearby.
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.

4. If the alert persists, try using a different wall plug adapter (see steps above to make sure the adapter is fully
connected to your Mobile Connector).a.
If the alert is no longer present, the issue is likely with the wall plug adapter you were using previously.
b.
If the alert persists, the issue is likely with your Mobile Connector.
If needed, obtain another wall plug adapter or Mobile Connector.
In the meantime, you can continue to charge with the same equipment. The charge rate will be reduced, as charge
current will be limited to 8A while this condition persists.

Your Mobile Connector is unable to communicate with the wall plug adapter. Because your Mobile Connector cannot
identify the type of wall outlet the wall plug adapter is connected to, charge current is automatically reduced to 8A.
What to do:
1.
Unplug your Mobile Connector, including the wall plug adapter, completely from the wall outlet.
2.
Make sure the connection between the wall plug adapter and the main body of your Mobile Connector is secure.
a.
Disconnect the wall plug adapter completely from the main body of your Mobile Connector.
b.
Fully reinsert the wall plug adapter into the main body of your Mobile Connector by pushing it into the socket until it snaps into place.
3.
Try charging again by plugging the Mobile Connector, including wall plug adapter, fully into the wall outlet.
4.
If the alert persists, try using a different wall plug adapter (see steps above to make sure the adapter is fully
connected to your Mobile Connector).
a.
If the alert is no longer present, the issue is likely with the wall plug adapter you were using previously.
b.
If the alert persists, the issue is likely with your Mobile Connector.
If needed, obtain another wall plug adapter or Mobile Connector. In the meantime, you can continue to charge with
the same equipment. The charge rate will be reduced, as charge current will be limited to 8A while this condition
persists.

This is not typically an issue with your vehicle or your Mobile Connector, but rather an issue with the outlet. 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.

Charge rate reduced - Handle temperature high
Check charge handle or charge port for debris
What this alert means:
Charge current has been temporarily reduced because the Mobile Connector has detected increased temperature in
the charge handle that connects to your vehicle

It is possible your vehicle will shut down unexpectedly. It is also possible that your vehicle will not restart after the
current drive.
You may notice that some nonessential features are not available. This is expected behavior due to your vehicle
preserving energy for essential functions.
What to do:
If this alert is present while you are driving, your vehicle needs to come to a stop as soon as possible. Pull over safely
at your earliest opportunity.
It is recommended that you eliminate or reduce your use of any nonessential features. This can help your vehicle
maintain adequate electrical power for essential functions other than driving, until it can be serviced.
If this alert remains present, it is recommended that you schedule service immediately. Without service, your vehicle
may not drive, may shut down unexpectedly, or may not restart.

Electrical system backup power is unavailable
Vehicle will consume more energy while idle
What this alert means:
The backup power source for the electrical system, the low voltage battery, is not available or cannot provide the
voltage required to support all vehicle features.
The primary source of electrical power, the high voltage battery system, will continue to support vehicle functions,
even when your vehicle is idle. For more information on the high voltage battery, see
About the High Voltage Battery
on page 178.
You may notice that some nonessential features are not available. This is expected behavior due to your vehicle
preserving energy for essential functions.
You may also notice that your vehicle consumes more energy than usual when you are not driving it, or that your vehicle displays a lower projected range than you would normally expect after charging. This is normal vehicle behavior when this alert is present, and it will continue until the backup power source is restored.
There is a chance that an issue affecting the primary power source could cause your vehicle to shut down
unexpectedly.
What to do:
It is recommended that you limit or avoid the use of any nonessential features. This can help your vehicle maintain
adequate electrical power for essential functions.
It is recommended that you schedule service at your earliest opportunity, so the backup power source for the
electrical system can be restored.

PULL OVER SAFELY
What this alert means:
The electrical system cannot provide adequate support to drive or continue driving. Your vehicle is preparing to shut
down to preserve energy for essential functions other than driving.
Your vehicle cannot be driven or continue driving while this condition continues.
