Quick answer

CC_a011 means the Tesla Wall Connector has activated over-temperature protection (latchoff), so charging is unavailable until it cools. Ensure the Wall Connector is not covered and that no heat source is nearby. If the alert persists in ambient temperatures below 100°F (38°C), service is required.

1. What does CC_a011 mean?

CC_a011 means the Tesla Wall Connector has activated over-temperature protection (latchoff), so charging is unavailable until it cools. Ensure the Wall Connector is not covered and that no heat source is nearby. If the alert persists in ambient temperatures below 100°F (38°C), service is required.

2. Technical explanation

Verified Tesla owner-manual material filed with NHTSA describes CC_a011 as “Unable to charge - Wall Connector too hot Let Wall Connector cool and try again.” The stated meaning is Wall Connector over-temperature protection (latchoff). This evidence identifies the charging equipment—not a confirmed vehicle high-voltage battery fault—as the component reporting the temperature-related condition.

3. What system is affected?

Tesla Wall Connector / AC charging equipment.

4. How serious is this code?

The database severity is listed as unknown. The verified guidance confirms charging is unavailable while the Wall Connector’s over-temperature protection is active.

5. Symptoms you may notice

  • The vehicle displays CC_a011: “Unable to charge - Wall Connector too hot Let Wall Connector cool and try again.”
  • Charging is unavailable while the alert is active.

6. Possible causes

  • Wall Connector over-temperature protection (latchoff) is active.
  • The Wall Connector may be covered.
  • A heat source may be nearby.
  • Any additional cause is 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?

No while CC_a011 is active; the verified alert states charging is unavailable. Charging may be tried again after the Wall Connector has cooled.

9. What you can safely do

  • Allow the Wall Connector to cool.
  • Make sure the Wall Connector is not covered by anything.
  • Make sure there is no heat source nearby.
  • After cooling, try charging again.
  • If the condition persists at normal ambient temperatures below 100°F (38°C), arrange Wall Connector service.

10. Step-by-step troubleshooting

  1. Confirm the Wall Connector is uncovered.
  2. Confirm no nearby heat source is contributing to the condition.
  3. Let the Wall Connector cool, then reconnect it to the vehicle and try charging again.
  4. Do not attempt internal Wall Connector or electrical-supply repairs yourself; verified material directs users to the Wall Connector installation guide and service when the issue persists.

11. When to contact service

Service is required if CC_a011 persists in normal ambient temperatures below 100°F (38°C). The verified material states that a persistent issue means the Wall Connector requires service; consult the installation guide for the specific Wall Connector.

12. What the service center may check

  • Inspect the Wall Connector and its installation in accordance with the applicable Wall Connector installation guide.
  • Evaluate the Wall Connector for the persistent over-temperature condition. Specific diagnostic steps are not yet established by verified evidence.

13. Possible repair or resolution

  • Allow the Wall Connector to cool and remove external heat or covering concerns if present.
  • If the alert persists, have the Wall Connector serviced. A specific repair or part replacement is not yet established by verified evidence.
