1. What does CC_f002 mean?

Tesla alert CC_f002 means charging was stopped or cannot begin because a ground fault was detected. Tesla describes this as current leaking through an unsafe path and advises disconnecting and reconnecting the Wall Connector; if the issue persists, use different charging equipment and have the Wall Connector grounding inspected by an electrician.

2. Technical explanation

Verified Tesla owner-documentation communications filed with NHTSA describe CC_f002 as: “Unable to charge - Insufficient grounding.” The documented meaning is a ground fault: current is leaking through an unsafe path. Tesla identifies a possible line-to-ground or neutral-to-ground fault. The evidence does not establish which specific component or installation condition is responsible in an individual case.

3. What system is affected?

Charging equipment and its grounding path, including the Wall Connector and its electrical supply grounding. The documents specifically reference grounding at the circuit breaker or power distribution box and connections to the Wall Connector.

4. How serious is this code?

The database severity is unknown. However, Tesla’s documented alert concerns a ground fault and insufficient grounding, so charging should not be forced or bypassed.

5. Symptoms you may notice

  • The vehicle displays CC_f002: “Unable to charge - Insufficient grounding.”
  • Charging is unable to start or continue with the affected equipment.

6. Possible causes

  • Ground fault.
  • Current leaking through an unsafe path.
  • Possible line-to-ground fault.
  • Possible neutral-to-ground fault.
  • The verified evidence does not establish a more specific cause for an individual vehicle or charging installation.

7. Can I still drive the vehicle?

Not yet established by verified evidence.

8. Can I charge the vehicle?

The affected charging attempt cannot proceed while CC_f002 is present. Tesla advises retrying after disconnecting and reconnecting the Wall Connector; if the issue persists, use different equipment. Overall safe-to-charge status is not established by the supplied database.

9. What you can safely do

  • Disconnect the Wall Connector from the vehicle and reconnect it, then try charging again.
  • If the alert persists, use different charging equipment.
  • Have the Wall Connector inspected by an electrician to confirm proper grounding.
  • Do not attempt to bypass grounding protections or perform electrical repairs yourself.

10. Step-by-step troubleshooting

  1. Retry charging by disconnecting the Wall Connector from the vehicle and reconnecting it.
  2. If CC_f002 returns, try different charging equipment.
  3. For a Wall Connector installation, arrange for an electrician to inspect grounding at the circuit breaker or power distribution box and the applicable Wall Connector connections.
  4. Refer to the Wall Connector installation guide for further information.

11. When to contact service

Contact a qualified electrician for inspection of the Wall Connector installation and grounding if the issue persists. Tesla service involvement is not specifically established by the supplied evidence.

12. What the service center may check

  • Inspect the Wall Connector to ensure it is properly grounded.
  • Verify proper grounding at the circuit breaker or power distribution box.
  • Verify appropriate connections to the Wall Connector.

13. Possible repair or resolution

  • Not yet established by verified evidence. The supplied documentation directs electrical inspection of grounding and Wall Connector connections; it does not specify a particular repair or replacement.
