UMC_a012
Charging equipment communication error
Try again or try dierent equipment
What this alert means:
Your vehicle is unable to charge because it cannot communicate eectively with the Mobile Connector. The Mobile
Connector detects that it cannot generate or maintain a valid control pilot signal.
What to do:
First, confirm the lack of eective 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 dierent 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 164 for more
details.

2.
Make sure the connection between the wall plug adapter and the main body of your Mobile Connector is secure.

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.
