1. What does CC_a041 mean?

Tesla alert CC_a041 means the Wall Connector detected high temperature at its building connection. Charging was reduced to protect the wiring and Wall Connector; the outlet or Wall Connector wiring must be checked.

2. Technical explanation

Verified Tesla owner-manual material filed with NHTSA states that high-temperature-detected-by-Wall-Connector alerts mean the building connection to the Wall Connector is getting too warm. The vehicle reduces charging speed to protect the wiring and Wall Connector. The supplied evidence identifies this as not typically an issue with the vehicle itself.

3. What system is affected?

External AC charging equipment: the building connection to the Tesla Wall Connector, including the outlet or Wall Connector wiring.

4. How serious is this code?

Unknown. The alert confirms a high-temperature condition at the Wall Connector building connection and a protective reduction in charge rate, but no formal severity classification is established by the supplied evidence.

5. Symptoms you may notice

  • A CC_a041 alert: “Charge rate reduced - Wall connection hot Outlet or Wall Connector wiring must be checked.”
  • Charging is slowed.
  • The Wall Connector has detected high temperature at its building connection.

6. Possible causes

  • The building connection to the Wall Connector is getting too warm.
  • The supplied evidence directs that the outlet or Wall Connector wiring must be checked.
  • Specific underlying electrical defects are not yet established by verified evidence.

7. Can I still drive the vehicle?

Not yet established by verified evidence.

8. Can I charge the vehicle?

Not yet established by verified evidence. Verified evidence states that charging has been slowed to protect the wiring and Wall Connector.

9. What you can safely do

  • Have the outlet or Wall Connector wiring checked by an electrician.
  • Use the Wall Connector installation guide for further information, as directed by the verified Tesla material.
  • Do not attempt electrical or high-voltage repairs yourself.

10. Step-by-step troubleshooting

  1. The verified owner-manual guidance is to have an electrician inspect the relevant building connection, outlet, or Wall Connector wiring.
  2. If multiple Wall Connectors are paired, Tesla material recommends that an electrician inspect their type labels and confirm that their current capabilities match.
  3. For paired Wall Connectors, Tesla further recommends pairing units with the same part number as an easy way to help ensure compatibility.

11. When to contact service

Contact a qualified electrician to inspect the outlet or Wall Connector wiring. Tesla vehicle service requirements are not yet established by verified evidence.

12. What the service center may check

  • Inspect the building connection to the Wall Connector for the source of the detected high temperature.
  • Inspect the outlet or Wall Connector wiring.
  • For paired Wall Connectors, inspect type labels and verify matching current capabilities.
  • For paired Wall Connectors, confirm whether units have the same part number, consistent with Tesla's recommendation.

13. Possible repair or resolution

  • A specific repair or resolution is not yet established by verified evidence. The verified direction is electrical inspection of the outlet or Wall Connector wiring by an electrician.
