1. What does CC_f025 mean?

Tesla alert CC_f025 means charging is unavailable because the Wall Connector detected an internal hardware issue and needs service.

2. Technical explanation

Verified Tesla owner-documentation evidence describes CC_f025 as a Wall Connector hardware issue. The alert may be associated with a contactor not working, a failed self-test of the internal ground-fault monitoring circuit, a disconnected thermal sensor, or another Wall Connector hardware-component issue. The alert identifies the Wall Connector rather than establishing a vehicle-side fault.

3. What system is affected?

Tesla Wall Connector / AC charging equipment.

4. How serious is this code?

Unknown. The supplied verified evidence does not assign a severity level.

5. Symptoms you may notice

  • Unable to charge.
  • Tesla displays CC_f025: “Unable to charge - Wall Connector issue Wall Connector needs service.”

6. Possible causes

  • Wall Connector contactor not working.
  • Wall Connector internal ground-fault monitoring circuit self-test failed.
  • Wall Connector thermal sensor disconnected.
  • Other 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 alert states that charging is unavailable. Whether charging is possible through another charging source is not yet established by verified evidence.

9. What you can safely do

  • Arrange service for the Wall Connector.
  • Refer to the applicable Wall Connector installation guide for Wall Connector information.

10. Step-by-step troubleshooting

  1. Do not attempt internal Wall Connector repair based on this alert. The verified evidence identifies an internal Wall Connector issue and states that the unit needs service.
  2. If Wall Connectors are paired for load sharing, verified documentation states that the primary unit must be set to an operating-current setting that allows each paired Wall Connector to receive at least 6 A. Example from the documentation: three paired Wall Connectors require the primary unit to be set to at least 18 A. This load-sharing information does not establish the cause of CC_f025.

11. When to contact service

Service is indicated for the Wall Connector. The supplied evidence does not specify the service provider or repair process.

12. What the service center may check

  • Inspect and diagnose the Wall Connector for an internal hardware issue.
  • Check Wall Connector contactor operation.
  • Check the self-test status of the internal ground-fault monitoring circuit.
  • Check the Wall Connector thermal-sensor connection.
  • Assess other Wall Connector hardware components as applicable.

13. Possible repair or resolution

  • Wall Connector service is required according to the alert. The exact repair or replacement resolution is not yet established by verified evidence.
