Bulletin Classification: This campaign bulletin addresses a known non-safety-related condition and provides
recommended technical diagnosis and repair procedures. Apply this procedure to all vehicles in the affected VIN range
listed. These instructions assume knowledge of motor vehicle and high voltage electrical component repairs, and should
only be executed by trained professionals. Tesla assumes no liability for injury or property damage due to a failure to
properly follow these instructions or repairs attempted by unqualified individuals.
Condition
On some Model 3 vehicles, an electrostatic discharge might damage the charge port ECU radio transceiver. As a result,
an alert displays on the touchscreen, and the charge port door is unable to be opened using the button on a charger
handle. The charge port door opens using other methods.
Correction
Inspect the vehicle for symptoms related to the condition. If necessary, replace the charge port ECU with an updated
component.
