by Wall Connector
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
