To regain normal charge operation, 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.

Wall plug adapter error - Charge rate reduced
Plug adapter fully into Mobile Connector and retry
Your Mobile Connector is unable to communicate with the wall plug adapter. Because your Mobile Connector cannot
monitor the wall plug adapter temperature, charge current is automatically reduced to 8A.
It is recommended that you try the following troubleshooting steps:
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.
It is recommended that you obtain another wall plug adapter or Mobile Connector as needed, based on the
troubleshooting steps above.
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.
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 150
for more
details. Additional third-party charging stations may also be available in your area to help you to pinpoint the issue.
