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 under Controls > Service
> Notifications 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 169.
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.
Wall Connector installation guides can be found here.
CP_a102
Unable to charge - Wall connection too 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.
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

Reduced braking performance is usually temporary, and can occur for a number of reasons including high brake
temperatures after heavy brake use, or driving in extremely cold or wet conditions. It can also indicate that your
brake pads or rotors have worn to the point that normal replacement is needed.
If you continue to experience reduced braking performance which does not improve over time, please contact Tesla
service at your convenience for a brake inspection.
For more information, see Hydraulic Fade Compensation on page 66.
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.
Further troubleshooting tips based on equipment type:

What to do:
This alert is often accompanied by other alerts that can help you identify and troubleshoot the issue. Start by
investigating any other displayed alerts that relate to charging issues.
Alternatively, you can check Mobile Connector or Wall Connector status lights to confirm power to the device, and
also refer to the product owner

PCS_a052
External charging equipment not providing power
Check power source or try different equipment
What this alert means:
Charging cannot begin due to a condition that prevents your vehicle from charging with AC power. DC fast charging / Supercharging should still function as expected.
Your vehicle has requested AC power from the external charging equipment, but the onboard charger does not detect any supply voltage coming from the equipment.
This can sometimes be caused by a hardware issue specific to the external charging equipment, which prevents the
charging equipment from switching power to the vehicle on or
off when requested. It could also occur due to
another condition
affecting the external charging equipment, the power source it is connected to, or your vehicle
itself.
What to do:
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.
Try charging with multiple, different types of charging equipment.
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

The vehicle cannot charge because the ground-fault circuit interrupter (GFCI) in the Mobile Connector has tripped.
Like the GFCI in a wall outlet, this feature is designed to stop the flow of electricity when there is a problem. It has
interrupted charging to protect your vehicle and the charging equipment.
This could happen for many reasons. The problem could be in the charge cable, the charge handle, the charge port,
or even an onboard vehicle component.
What to do:
Inspect the charge port and the charge handle for pooled water or unusual levels of moisture. If you find excessive
moisture, wait and let both the inside area of the charge port and the exposed portion of the charge handle dry
sufficiently before trying again.
Inspect the charge equipment for damage.
