Your vehicle's onboard charger is detecting input voltage at the charge port when no power has
been requested from the external charging equipment, which indicates the external charging
equipment is not functioning as expected.
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 o when
requested. It could also occur due to another condition aecting the external charging
equipment, or a condition aecting your vehicle itself.
As this alert is usually specific to external charging equipment, 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.
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 on page 146 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.

Charging slowed - Some AC phases not powered
Check power source and charging equipment
Charging speed has been reduced due to a condition that aects your vehicle’s ability to charge
with AC power. DC fast charging / Supercharging should still function as expected.
Your vehicle's onboard charger has detected that one or more power converters is not receiving
the necessary AC input voltage. For example: during three-phase charging, one phase might be
missing from the AC input power provided by the external source. This could occur due to a
condition
aecting the external charging equipment, the power source it is connected to, or
your vehicle itself.
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.
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
