1. What does CHG_u010 mean?

CHG_u010 means AC charging cannot begin because the vehicle detects input voltage at the charge port when it should not. Tesla directs the driver to try different charging equipment. DC fast charging/Supercharging should still function as expected.

2. Technical explanation

Tesla documentation identifies CHG_u010 as “External charging equipment error detected — Try different charging equipment.” The alert applies to an AC-charging condition: the onboard charger detects input voltage at the charge port when it should not, preventing AC charging from starting. The available verified evidence does not establish a specific failed component or a complete repair procedure.

3. What system is affected?

AC charging equipment interaction and the vehicle’s onboard charging system.

4. How serious is this code?

Unknown. The diagnostic record does not assign a severity.

5. Symptoms you may notice

  • CHG_u010 alert is displayed.
  • AC charging cannot begin.
  • DC fast charging/Supercharging should still function as expected.

6. Possible causes

  • A condition prevents AC charging from starting because the onboard charger detects input voltage at the charge port when it should not.
  • If charging works with different equipment, Tesla documentation indicates the issue was likely with the original charging equipment.
  • If charging still does not work with different equipment, Tesla documentation indicates the issue may be with the vehicle.

7. Can I still drive the vehicle?

Not yet established by verified evidence.

8. Can I charge the vehicle?

AC charging cannot begin with the condition identified by this alert. DC fast charging/Supercharging should still function as expected.

9. What you can safely do

  • Try different AC charging equipment.
  • Try charging at a Tesla Supercharger or Destination Charging location using the locations shown on the vehicle touchscreen map.
  • Do not attempt high-voltage repairs or disassembly.

10. Step-by-step troubleshooting

  1. Attempt AC charging using different charging equipment.
  2. If the vehicle charges with different equipment, the original equipment was likely the issue.
  3. If the vehicle still does not charge with different equipment, the issue may be with the vehicle.
  4. Try a Tesla Supercharger or Destination Charging location.

11. When to contact service

If the vehicle still does not charge after trying different charging equipment, the issue may be with the vehicle. Contact Tesla service for evaluation. Further urgency or service requirements are not yet established by verified evidence.

12. What the service center may check

  • Determine whether AC charging succeeds with different charging equipment.
  • Determine whether the vehicle can charge at a Tesla Supercharger or Destination Charging location.
  • No further service inspection steps are established by the supplied verified evidence.

13. Possible repair or resolution

  • Not yet established by verified evidence.
