Charge rate reduced - Wall connection hot
Outlet or Wall Connector wiring must be checked
High temperature detected by Wall Connector alerts indicate the building connection to the
Wall Connector is getting too warm, so charging has been slowed to protect the wiring and Wall
Connector.
This is not typically an issue with your vehicle or your Wall Connector, but rather an issue with the building wiring. This may be caused by a loose building wiring connection to the Wall
Connector and can be
fixed quickly by an electrician.
To regain normal charge speed, 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.
Wall Connector installation guides can be found here.

Charging equipment not recognized
Try again or try different equipment
The charge port is unable to detect whether a charge cable is inserted or the type of charge
cable connected.
If this alert appears while a charge cable is connected, it should be determined whether the
issue is caused by the charging equipment or the vehicle. Try charging the vehicle using
different external charging equipment (charge cable, charging station, charging stall, etc.).

Unable to charge - Wall plug temperature high
Wall outlet and wiring inspection recommended
High temperature detected by Mobile Connector alerts indicate the outlet used to charge is
becoming too warm, so charging has stopped to protect the outlet.
This is not typically an issue with your vehicle or your Mobile Connector, but rather an issue with the outlet. A warm outlet may be caused by a plug that is not fully inserted, a loose building
wiring connection to the outlet, or an outlet that is beginning to wear out.
To regain normal charge operation, make sure your adapter is fully plugged into the outlet. If
charging speed does not return to normal, contact an electrician to inspect the outlet and building wiring connections to the outlet and complete any repairs needed.
If the outlet is worn, it should be replaced with a high-quality outlet. Consider upgrading to a
Tesla Wall Connector for greater convenience and highest charging speed.

Electrical system power reduced
Vehicle may shut down unexpectedly
The electrical system cannot maintain the voltage required to support all vehicle features.
If this alert is present while you are driving, it is possible your vehicle will shut down unexpectedly. It is also possible that your vehicle will not restart after the current drive.
If this alert is present when your vehicle is in Park or when it first wakes, it is possible your
vehicle may not have adequate electrical power to start driving. A separate vehicle alert may be
present to indicate that condition.
It is recommended that you eliminate or reduce your use of any nonessential features. This can
help your vehicle maintain adequate electrical power for essential functions.
If this alert remains active, it is recommended you schedule service immediately. Without
service, your vehicle may not drive, may shut down unexpectedly, or may not restart.
