• Detects an unexpected increase in supply voltage from the wall outlet.

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. Contact an electrician to inspect the building wiring connection to that outlet.

If the vehicle still does not charge when you try a dierent wall outlet, try charging at a dierent 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 Maps and Navigation on page 164 for more

details.
