External charging equipment not providing power
Check power source or try dierent equipment
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 o when
requested. It could also occur due to another condition
aecting 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,
dierent 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 152 for more details. Additional third-party charging stations may
also be available in your area to help you to pinpoint the issue.
