What this alert means:
Incorrect rotary switch setting.
What to do:
Have your electrician adjust the Wall Connector’s internal rotary switch to a valid operating current setting. They should first make sure there is no power to the Wall Connector. The correlation between switch setting and current should be printed on the inside of the Wall Connector. Your electrician should also refer to the Set the Operating Current section in the Wall Connector Installation Manual.
If the Wall Connector is set up for load sharing (circuit breaker sharing) and paired with other Wall Connectors, the rotary switch of the primary unit must be set to an operating current setting that allows each paired Wall Connector to receive at least 6A of charge current.
Example: Three Wall Connectors are paired for load sharing. The primary unit needs to be set to a current of at least 3 * 6A = 18A or greater.
For more information, see the installation guide for your Wall Connector.
What this alert means:
A communication error occurred between the Wall Connector and the vehicle.
What to do:
Try charging again by disconnecting the Wall Connector from the vehicle and reconnecting.
- If the issue persists, turn OFF the circuit breaker servicing the Wall Connector, wait 10 seconds, turn the circuit breaker ON again, then try reconnecting the Wall Connector to the vehicle.
- If the issue persists and other charging equipment is available, plug the vehicle into another Wall Connector or a Mobile Connector to determine if the vehicle is able to communicate with other charging equipment.
- If the issue persists, service is required.
For more information, see the installation guide for your Wall Connector.
What this alert means:
Load sharing (circuit breaker sharing) network: The paired Wall Connectors have different maximum current capabilities.
What to do:
Only Wall Connectors with the same maximum current capabilities can be paired in a load sharing (circuit breaker sharing) network. Have your electrician inspect the type labels on the Wall Connectors and make sure the current capabilities match. It is further recommended that your electrician only pair Wall Connectors with the same part number, as an easy way to make sure paired units are compatible.
For more information, see the installation guide for your Wall Connector.
What this alert means:
High temperature detected by Wall Connector alerts indicate the building connection to the Wall Connector is getting too warm, so charging has been slowed to protect the wiring and Wall Connector.
This is not typically an issue with your vehicle or your Wall Connector, but rather an issue with the building wiring. This may be caused by a loose building wiring connection to the Wall Connector and can be fixed quickly by an electrician.
What to do:
Contact an electrician to inspect the building wiring connection to the Wall Connector. They should make sure that all wires are properly connected and torqued according to the installation guide for the Wall Connector.
For more information, see the installation guide for your Wall Connector.
What this alert means:
Wall Connector configuration is incomplete.
What to do:
The Wall Connector needs to be commissioned to appropriately configure the circuit breaker size and protective earth connection type.
For more information, refer to Commissioning Procedure in the Wall Connector Installation Manual. If the issue persists, contact an electrician to inspect the building wiring connection to the Wall Connector. They should make sure the power output and grounding connections are properly configured according to the installation guide for the Wall Connector.
For more information, see the installation guide for your Wall Connector.
What this alert means:
The charge port is unable to detect whether a charge cable is inserted, or the type of charge cable connected.
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.
What to do:
If this alert appears while a charge cable is connected, determine whether the issue is caused by the charging equipment or the vehicle. 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 this alert appears while a charge cable is not connected or if the issue is suspected to be with the vehicle, inspect the charge port inlet and the charge cable connector for any obstructions, such as debris, moisture, and/or foreign objects. Make sure any charge port inlet obstruction has been removed and any moisture has been allowed to dry, then try re-inserting the cable into the charge port.
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.

What this alert means:
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.
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.
What to do:
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, such as debris, moisture, and/or foreign objects. Make sure any charge port inlet obstruction has been removed and any moisture has been allowed to dry, then try re-inserting the cable into the charge port.

What this alert means:
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.
What to do:
Try closing the charge port door and then opening it again.
For more information, see Opening the Charge Port.
For more information on charging, see Charging Instructions.
What this alert means:
Charging stopped because communication between the vehicle and the external charging equipment was interrupted.
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.
What to do:
Confirm whether the external charging equipment is powered by looking for any status lights, displays, or other indicators on the equipment.
If the equipment is not powered, try to restore the external charging equipment’s power source.
- If attempting to charge at a public station and power is unable to be restored, contact the station operator.
- If attempting to charge at a private station (for example: charging at home) and power is unable to be restored, contact an electrician.
If the equipment is powered, try charging the vehicle using different external charging equipment.
- 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.
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.

What this alert means:
One of the charge port door sensors is not communicating properly. The charge port may not recognize the request to open when the charge port door is pressed.
What to do:
You can still use all other usual methods to open the charge port door:
- Use the vehicle touchscreen.
- Use the Tesla Mobile App.
- With your vehicle unlocked, press the charge handle button on any Tesla charge cable, including a Wall Connector, Mobile Connector, or Supercharger.
- Hold and press the trunk button on your key fob.
