Warning

Only technicians who have been trained in High Voltage Awareness and have completed all required certification courses (if applicable) are permitted to perform this procedure. Proper personal protective equipment (PPE) and insulating HV gloves with a minimum rating of class 0 (1000V) must be worn at all times a high voltage cable, busbar, or fitting is handled. Refer to Tech Note TN-15-92-003, High Voltage Awareness Care Points for additional safety information.

Warning

Make sure that the HV gloves are not expired. HV gloves can be used up to 12 months after the testing date printed on the glove, but only 6 months after first use even if the gloves are still within the 12-month period.

Remove

  1. Open all doors and lower the windows.
  2. Move both front seats forward.
  3. Open the trunk and the charge port door.
  4. Perform the charge port voltage check procedure. See Charge Port Voltage Check.
