Tesla MODEL X 2015 Owner's Manual page 249

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 off when requested. It could also occur due to
another condition affecting the external charging equipment, or a condition affecting 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, 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's touchscreen display. See
details. Additional third-party charging stations may also be available in your area to help you to pinpoint the issue.

Charging slowed - Poor grid power quality possible
Unplug and retry / Try different charging location
Charging speed has been reduced due to a condition that affects your vehicle's ability to charge 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 affecting 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 different wall outlet.
◦ If charging speed is no longer reduced, 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 charging speed is still reduced, the issue may be with the Mobile Connector or the electrical grid.
• If using a Wall Connector, try charging your vehicle with different charging equipment like a Mobile Connector
powered by a separate wall outlet.
◦ If charging speed is no longer reduced, 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 different wall outlets.
• Try charging with multiple, different types of charging equipment at different 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
details. Additional third-party charging stations may also be available in your area to help you to pinpoint the issue.
