Tesla UMC_a016 Mobile Connector control box temperature high Maximum charge rate reduced
What this alert means:
Charge current has been temporarily reduced because the Mobile Connector has detected increased temperature inside its control box housing.
What to do:
Make sure the Mobile Connector is not covered by anything, and that there is no heat source nearby. If the problem persists in normal ambient temperatures (under 100°F or 38°C), 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.
