Charging equipment communication error
Try again or try different equipment
What this alert means:
Your vehicle is unable to charge because it cannot communicate effectively with the Mobile Connector. The Mobile Connector
cannot confirm via proximity detection that the charge handle is fully connected to your vehicle.
What to do:
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.
•
If the vehicle begins charging, the issue was likely with the Mobile Connector.
•
If the vehicle still does not charge, the issue may be with the vehicle.
Inspect the charge port inlet and the Mobile Connector handle for any obstructions (use a flashlight as necessary). Make sure
any obstruction has been removed and any moisture has been allowed to dry, then try re-inserting the Mobile Connector
handle into the charge port.
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's touchscreen display. See Maps and Navigation on page 144 for more details.
For more information on troubleshooting Mobile Connector status lights and charging issues, refer to the product's owner's
manual.
For more information on charging, see Charging Instructions on page 159.
