Tesla Model S: Charging equipment communication error

Try again or try different equipment

Your vehicle is unable to charge because it cannot communicate effectively with the external charging equipment. It cannot sense a valid control pilot signal coming from the charging equipment.

First, confirm the lack of effective communication is caused by the external charging equipment rather than an issue with your vehicle. This is usually the case.

Try charging the vehicle using different external charging equipment (including charge cable, charging station, or charging stall).

  • If the vehicle begins charging, the issue was likely with the equipment.
  • If the vehicle still does not charge, the issue may be with the vehicle.

If the issue is suspected to be with the vehicle, inspect the charge port inlet and the charge cable connector for any obstructions (use a flashlight as necessary). Debris, moisture, and/or foreign objects present in the charge port inlet or the charge cable connector can prevent the charge port from properly communicating with the charging equipment.

It is recommended that any debris / foreign objects be removed and any moisture be allowed to dry. Afterward, try re-inserting the cable into the charge port. Charging should now be possible.

As this alert is usually specific to external charging equipment and power sources, and it does not typically indicate an issue with your vehicle that can be resolved by scheduling service, it is recommended that you:

  • Try charging with multiple, different types of charging equipment.
  • Make sure any charge port inlet obstruction has been removed.

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 or Wall Connector status lights, refer to the product's Owner's Manual at Charging & Adapter Product Guides. If using other external charging equipment, refer to the manufacturer's provided documentation for troubleshooting tips.

For more information on charging, see Charging Instructions.

Charge port door sensor fault

Charge port may not operate as expected

One of the charge port door sensors is not functioning normally. When this occurs, the charge port may be unable to accurately sense the charge port door position and the charge port may not operate as expected.

  • The charge port latch may intermittently remain engaged when the charge port door is opened.
  • The charge port light may illuminate only intermittently when the charge port door is opened.

If you encounter these or similar behaviors while the alert is present, try closing the charge port door and then opening it again to restore normal function.

For more information, see Opening the Charge Port.
