(PCS_a016)
Cannot charge - Poor grid power quality possible
Retry / Try other charge location or Supercharging
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 condition could occur due to power supply disturbances caused by the external charging
equipment or by the electrical power grid. In some cases, this condition can even result from
turning on 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
aecting AC charging.
This alert is often accompanied by other alerts that can help you identify and troubleshoot the
condition. Start by investigating any other displayed alerts that relate to charging.
Further troubleshooting tips based on equipment type:
•
If using a Mobile Connector, try charging your vehicle with a dierent wall outlet.
◦
If your vehicle starts to charge and continues to charge as expected, 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 your vehicle still does not start to charge, or does not continue to charge as expected,
the issue may be with the Mobile Connector or the electrical grid.
• If using a Wall Connector, try charging your vehicle with dierent charging equipment like a
Mobile Connector powered by a separate wall outlet.
◦ If your vehicle starts to charge and continues to charge as expected, 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 multiple, dierent types of charging equipment at dierent locations.
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.

troubleshooting tips.
