Tesla Model S: Mobile Connector to adapter connection hot

Maximum charge rate reduced

Charge current has been reduced because the Mobile Connector has detected a high temperature at the connection between the wall plug adapter and the control box.

Make sure the wall plug adapter is fully connected to the Mobile Connector control box.

After unplugging from the power source (wall outlet), you should also inspect the wall plug adapter connection and the Mobile Connector control box connection for any obstructions (use a flashlight as necessary). Debris or foreign objects present where the wall plug adapter and the Mobile Connector control box connect can cause increased temperatures during charging.

It is recommended that any debris / foreign objects be removed. Afterward, 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 charge current should no longer be reduced.

Also make sure the wall plug adapter is not covered by anything, and that there is no heat source nearby. If the issue persists in normal ambient temperatures (under 100ºF or 38ºC), service is required.

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 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 status lights and charging issues, refer to the product's owner's manual.
