2023 TESLA MODEL S charging

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
225Troubleshooting

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

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

What to do:
Confirm whether the external charging equipment is powered by looking for any status lights, displays, or other
indicators on the equipment. For more information on troubleshooting Mobile Connector or Wall Connector status
lights, refer to the product

What to do:
For more information and troubleshooting suggestions, check in your vehicle touchscreen for other recent alerts that involve charging.
CP_a066
Charging equipment not ready
See equipment instructions to start charging
What this alert means:
Charging cannot begin because the charging station is communicating to your vehicle that either the external
charging equipment is not ready or charging is not authorized. The control pilot signal that communicates between
the charging station and your vehicle indicates that your vehicle is not allowed to start charging.
This could occur because:

If the alert remains present, limited AC charging should still be available.
For more information on charging, see Charging Instructions on page 163.
CP_a101
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.

Unable to charge - Wall connection too hot
Outlet or Wall Connector wiring must be checked
What this alert means:

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.

CP_a143
Charging adapter has electric arc flash hazard
Use different charging equipment
What this alert means:
Charging is unavailable because your vehicle has detected an electric arc flash hazard in the third-party charging
adapter used to connect a Combined Charging System (CCS) charge handle to your vehicle

PCS_a016
Cannot charge - Poor grid power quality possible
Retry / Try other charge location or Supercharging
What this alert means:
Charging has stopped due to a condition that prevents your vehicle from charging with AC power. DC fast charging /
Supercharging should still function as expected.
This may be due to power supply disturbances caused by the external charging equipment or by the electrical
power grid. In some cases, this condition may be the result of using nearby electric devices that draw a lot of power.
If these possible causes can be ruled out, then a condition with your vehicle itself may also be affecting AC charging.
What to do:
If this alert is accompanied by another alert that specifies the condition affecting AC charging, start by investigating
that alert.
