1. What does CC_a014 mean?

Tesla alert CC_a014 means the Wall Connector detected an internal hardware issue and charging may be unavailable from that Wall Connector. Tesla’s published guidance says to ensure the connector is fully inserted, uncovered, and away from a heat source; if the issue persists below 100°F (38°C), service is required.

2. Technical explanation

Verified Tesla material filed with NHTSA identifies CC_a014 as: “Unable to charge - Wall Connector issue Wall Connector needs service.” The alert indicates that the Wall Connector detected an internal issue. The evidence identifies possible Wall Connector issues as a contactor not working, failure of the internal ground-fault-monitoring self-test, a disconnected thermal sensor, or another Wall Connector hardware-component issue. The evidence does not establish which one is present in an individual case.

3. What system is affected?

Tesla Wall Connector / charging equipment. The supplied evidence does not establish a fault in the vehicle’s high-voltage battery or onboard charging hardware.

4. How serious is this code?

Unknown. The verified database does establish that charging can be unavailable and that service is required if the alert persists in normal ambient temperatures below 100°F (38°C).

5. Symptoms you may notice

  • Tesla alert CC_a014 is displayed: “Unable to charge - Wall Connector issue Wall Connector needs service.”
  • Charging may be unavailable when using the affected Wall Connector.

6. Possible causes

  • Wall Connector contactor not working.
  • Wall Connector internal ground-fault-monitoring circuit self-test failed.
  • Wall Connector thermal sensor disconnected.
  • Another Wall Connector hardware-component issue.

7. Can I still drive the vehicle?

Not yet established by verified evidence.

8. Can I charge the vehicle?

The supplied evidence establishes that charging may be unavailable from the affected Wall Connector. Whether the vehicle can charge from another charging source is not yet established by verified evidence.

9. What you can safely do

  • Make sure the Wall Connector connector is fully inserted into the vehicle charge inlet.
  • Make sure the connector is not covered by anything.
  • Make sure there is no heat source nearby.
  • Refer to the installation guide for the Wall Connector.
  • If the issue persists in normal ambient temperatures below 100°F (38°C), obtain service.

10. Step-by-step troubleshooting

  1. Confirm that the connector is fully inserted into the vehicle charge inlet.
  2. Confirm that the connector is uncovered and no heat source is nearby.
  3. If CC_a014 continues below 100°F (38°C), service is required. Do not attempt internal Wall Connector repair based on this alert.

11. When to contact service

Service is required if the issue persists in normal ambient temperatures below 100°F (38°C).

12. What the service center may check

  • Evaluate the Wall Connector internal issue indicated by CC_a014.
  • Check whether the contactor is operating.
  • Check the internal ground-fault-monitoring circuit self-test result.
  • Check whether the thermal sensor is disconnected.
  • Assess for another Wall Connector hardware-component issue.

13. Possible repair or resolution

  • Not yet established by verified evidence. The supplied material directs the owner to obtain service if the condition persists and to consult the Wall Connector installation guide.
