Tesla Model S (2012-2024) Service Manual / High Voltage System / Charge Port - Single Phase - Motorized (Remove and Replace)

Warning: Only technicians who have been trained in High Voltage Awareness are permitted to perform this procedure. Proper personal protective equipment (PPE) and insulating HV gloves with a minimum rating of class 00 (500V) must be worn any time a high voltage cable is handled. Refer to Tech Note TN-15-92-003, "High Voltage Awareness Care Points" for additional safety information.

Warning: The high voltage harness must be removed from the charge port before the charge port is removed from the vehicle. Never remove the charge port from the vehicle without first disconnecting the high voltage harness. Failure to follow this requirement may result in serious injury or death due to exposure to high voltage. Only Service Technicians that have received and completed high voltage training are authorized to perform this service.

  • Ensure that both low voltage harnesses are fully seated.
  • Ensure that both the upper and lower HV covers are fully seated.
  • Test the charge port door for proper fit and operation. Adjust the charge port door as necessary.
  • Perform a vehicle firmware update if a new charge port was installed. This ensures that the charge port's firmware is at the same revision as the vehicle firmware
