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’s manual for
troubleshooting information based on blink codes. If
using other (non-Tesla) external charging equipment,
check for a display or other user interface that provides
troubleshooting help.
If there is clearly no power to the charging equipment,
check the circuit breaker for the wall outlet / Wall
Connector to make sure it has not tripped.
Further troubleshooting tips based on equipment type:
•
If using a Mobile Connector, try charging the vehicle
with a
dierent wall outlet.
◦ If the vehicle starts to charge, the issue was likely
with the original wall outlet. It is recommended
that you contact an electrician to inspect the
building wiring connection to that outlet.
◦
If the vehicle still does not charge, the issue may
be with the Mobile Connector.
•
If using a Wall Connector, try charging the vehicle
with dierent charging equipment like a Mobile
Connector powered by a separate wall outlet.
◦
If the vehicle starts to charge, the issue was likely
with the Wall Connector. 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.
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 dierent wall outlets.
•
Try charging with dierent 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's
touchscreen display. See Range Assurance on page 72
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.
(PCS_a053)
Charge rate reduced
Check for an extension cord or bad
utility wiring
Charging speed has been reduced because the onboard
charger in your vehicle has detected a large voltage
drop during charging.
Likely causes of this issue include:
• Problems with the building wiring and/or the wall
outlet.
• An extension cord or other wiring that cannot
support the requested charge current.
This issue can also result from turning on electric
devices that draw a lot of power from the same branch
circuit while the vehicle is charging.
If this issue has occurred multiple times at your normal
charging location, contact an electrician to inspect the
electrical installation. They should check the following:
•
Any installed charging equipment and its connection
to the building wiring.
•
The building wiring, including any wall outlet used
with a Mobile Connector.
•
The electrical connection to the power utility line
where it enters the building.
Discuss with the electrician whether the charge current
on the vehicle should be lowered, or if the installation
should be upgraded to support a higher charge current.
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, dierent types of
charging equipment at dierent locations.
•
Contact an electrician to inspect the wiring and
equipment at your normal charging location.
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 Range Assurance on page 72
for more details. Additional third-party charging
stations may also be available in your area to help you
to pinpoint the issue.

Connector or Wall Connector status lights, refer to the
