Tesla UMC_a004 Unable to charge with Mobile Connector Voltage too high / Try a different wall outlet
What this alert means:
- Detects the wall outlet voltage is too high, or
- Detects an unexpected increase in supply voltage from the wall outlet.
What to do:
Try charging the vehicle with a different 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 different wall outlet, try charging at a different 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 for more details.
