Quick answer

CHG_w032 means a Wall Connector detected high temperature at its building connection. Charging is reduced to protect the wiring and Wall Connector, and the outlet or Wall Connector wiring must be checked.

This page separates verified manufacturer/regulator evidence from supporting material. Unsupported causes, repairs or safety conclusions are not guessed.

1. What does CHG_w032 mean?

CHG_w032 means a Wall Connector detected high temperature at its building connection. Charging is reduced to protect the wiring and Wall Connector, and the outlet or Wall Connector wiring must be checked.

2. Technical explanation

Verified Tesla owner-documentation excerpts submitted to NHTSA state that this alert is triggered by high temperature detected by the Wall Connector. The building connection to the Wall Connector is getting too warm, so charging has been slowed to protect the wiring and Wall Connector. The alert title specifically directs that the outlet or Wall Connector wiring be checked.

3. What system is affected?

AC charging equipment: the Wall Connector and its building connection, including the outlet or Wall Connector wiring.

4. How serious is this code?

The database severity is unknown. Verified evidence does establish that charging has been reduced as a protective response to elevated temperature at the Wall Connector building connection.

5. Symptoms you may notice

  • CHG_w032 is displayed.
  • Charge rate is reduced.
  • A Wall Connector detects high temperature at its building connection.

6. Possible causes

  • The Wall Connector building connection is getting too warm.
  • The alert directs that the outlet or Wall Connector wiring be checked.
  • A more specific underlying cause is not yet established by verified evidence.

7. Can I still drive the vehicle?

Not yet established by verified evidence.

8. Can I charge the vehicle?

Not yet established by verified evidence. Verified evidence states that charging is slowed when this alert occurs.

9. What you can safely do

  • Arrange for the outlet or Wall Connector wiring to be checked.
  • Do not attempt high-voltage or electrical-wiring repair yourself.
  • Tesla documentation states that a Tesla Supercharger or Destination Charging location can be tried; these locations can be found using the vehicle touchscreen map.

10. Step-by-step troubleshooting

  1. Check whether CHG_w032 is present and whether the charge rate has been reduced.
  2. Have the outlet or Wall Connector wiring checked by an appropriately qualified professional.
  3. If using a different charging location, observe whether charging proceeds there. Tesla documentation identifies Tesla Supercharger and Destination Charging locations as alternatives.
  4. Whether any specific test result confirms a particular fault is not yet established by verified evidence.

11. When to contact service

The supplied evidence directs that the outlet or Wall Connector wiring be checked. Whether Tesla service is required is not yet established by verified evidence.

12. What the service center may check

  • Check the outlet or Wall Connector wiring.
  • Check the building connection to the Wall Connector for the condition associated with the alert: excessive temperature.

13. Possible repair or resolution

  • Charging is slowed to protect the wiring and Wall Connector.
  • The specific repair or final resolution is not yet established by verified evidence.
