Warning

This procedure is a DRAFT, although it has been validated. Warnings and Cautions might be missing. Follow safety requirements and use extreme caution when working on or near high voltage systems and components. Provide corrections and feedback to ServiceDevelopment@teslamotors.com.

Warning

Remove all jewelry (watches, bracelets, rings, necklaces, earrings, ID tags, piercings, etc.) from your person, and all objects (keys, coins, pens, pencils, tools, fasteners, etc.) from your pockets before performing any procedure that exposes you to high voltage.

Warning

If corrective eyewear is necessary to safely perform any procedure, make sure that the eyewear is securely restrained to the head and cannot fall off.

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

When servicing the ancillary bay cover and components in or around the ancillary bay, there is a possibility of encountering metal flashing on the inner edge of the vehicle single-piece rear casting. These sharp protrusions are a cut hazard, and proper PPE should be worn if there is a chance of contacting the flashing unprotected. If not already wearing leather over gloves, then at least wear cut-resistant gloves when the flashing is present.

- If the recycling warning label with CE marking and manufacturer information is present on the ancillary bay cover being replaced:
  1. Note the area where the recycling warning label is affixed on the ancillary bay cover being replaced.
  2. Clean the corresponding area on the new ancillary bay cover with an IPA wipe and allow 1 minute dry time.
  3. Install a new recycling label with CE marking and Manufacturing Information (part number 1108781-BB-F or 1108781-SH-F) on the new ancillary bay cover.
