What this alert means:
- Contactor not working
- Self-test of internal ground fault monitoring circuit failed
- Thermal sensor disconnected
- Other hardware component issues
What to do:
An internal issue was detected by the Wall Connector.
- Try charging again by disconnecting the Wall Connector from the vehicle and reconnecting.
- If the issue persists, turn OFF the circuit breaker for the Wall Connector, wait 10 seconds, and turn the circuit breaker ON again. Then try reconnecting the Wall Connector to the vehicle.
- If the issue persists, have an electrician make sure all wires are properly connected and torqued according to the instructions in the Wall Connector Installation Manual.
- Once your electrician has completed all work and restored power to the Wall Connector, try charging again by reconnecting the Wall Connector to the vehicle.
- If the issue persists, the Wall Connector requires service.
For more information, see the installation guide for your Wall Connector.
What this alert means:
Load sharing (circuit breaker sharing) network: Need one (and only one) Wall Connector set as primary.
What to do:
Only one Wall Connector can be set to a primary configuration. Have your electrician confirm:
- Only one of the Wall Connectors is set as primary.
- All other Wall Connectors linked to the primary unit are set to paired position (position F).
For more information, see the installation guide for your Wall Connector.

What this alert means:
Load sharing (circuit breaker sharing) network: More than three Wall Connectors are paired with the same primary unit.
What to do:
Consult your electrician to have one or more paired Wall Connectors moved to a different circuit and disconnected (unpaired) from this load sharing (circuit breaker sharing) network.
For more information, see the installation guide for your Wall Connector.
What this alert means:
Incorrect rotary switch setting.
What to do:
Have your electrician adjust the Wall Connector’s internal rotary switch to a valid operating current setting. They should first make sure there is no power to the Wall Connector. The correlation between switch setting and current should be printed on the inside of the Wall Connector. Your electrician should also refer to the Set the Operating Current section in the Wall Connector Installation Manual.
If the Wall Connector is set up for load sharing (circuit breaker sharing) and paired with other Wall Connectors, the rotary switch of the primary unit must be set to an operating current setting that allows each paired Wall Connector to receive at least 6A of charge current.
Example: Three Wall Connectors are paired for load sharing. The primary unit needs to be set to a current of at least 3 * 6A = 18A or greater.
For more information, see the installation guide for your Wall Connector.

What this alert means:
A communication error occurred between the Wall Connector and the vehicle.
What to do:
Try charging again by disconnecting the Wall Connector from the vehicle and reconnecting.
- If the issue persists, turn OFF the circuit breaker servicing the Wall Connector, wait 10 seconds, turn the circuit breaker ON again, then try reconnecting the Wall Connector to the vehicle.
- If the issue persists and other charging equipment is available, plug the vehicle into another Wall Connector or a Mobile Connector to determine if the vehicle is able to communicate with other charging equipment.
- If the issue persists, service is required.
