1. What does CC_f008 mean?

Tesla alert CC_f008 means charging is unavailable because the Wall Connector input voltage is too low and must be within the Wall Connector rating.

2. Technical explanation

Tesla describes CC_f008 as an over- or under-voltage protection alert. The supplied official NHTSA-hosted Tesla communications direct the owner to have an electrician ensure appropriate voltage at the circuit breaker serving the Wall Connector and to consult the Wall Connector installation guide.

3. What system is affected?

Wall Connector AC supply/input-voltage protection.

4. How serious is this code?

Severity is not yet established by verified evidence.

5. Symptoms you may notice

  • Unable to charge.
  • The vehicle displays CC_f008: “Unable to charge - Input voltage too low. Voltage must be within Wall Connector rating.”

6. Possible causes

  • Input voltage to the Wall Connector is too low or otherwise outside the Wall Connector rating.
  • The official material characterizes the condition as over- or under-voltage protection.

7. Can I still drive the vehicle?

Not yet established by verified evidence.

8. Can I charge the vehicle?
