CC_a023
Unable to charge - Too many Wall Connectors
Ensure no more than 3 units paired with primary
What this alert means:
Load sharing (circuit breaker sharing) network: More than three Wall Connectors are paired with the same primary
unit.
What to do:
Consult your electrician to have one or more paired Wall Connectors moved to a different circuit and disconnected
(unpaired) from this load sharing (circuit breaker sharing) network.
For more information, see the installation guide for your Wall Connector.

CC_a028
Unable to charge - Incorrect switch setting
Wall Connector rotary switch must be adjusted
What this alert means:
Incorrect rotary switch setting.
What to do:
Have your electrician adjust the Wall Connector

CC_a030
Unable to charge - Primary / paired unit mismatch
Wall Connector current ratings must match
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.
CC_a041
Charge rate reduced - Wall connection hot
Outlet or Wall Connector wiring must be checked
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.
CC_a043
Wall Connector configuration must be completed
Refer to Installation Guide to enable charging
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.
Troubleshooting Alerts

CP_a004
Charging equipment not recognized
Try again or try different equipment
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).

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
