Remove

Warning IconA warning icon, calling your attention to a possibly risky situation
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.
  1. Disconnect the LV power. See LV Battery - Li-lon (Disconnect and Connect).
  2. Remove the 2nd row lower seat cushion. See Seat Cushion - 2nd Row (Remove and Replace).
  3. Perform Vehicle HV Disablement Procedure. See Vehicle HV Disablement Procedure.
  4. Disconnect the electrical harness from the high voltage controller connector.
    Informational PurposesAn informational icon, calling your attention
    Note
    The HV battery positive contactor and negative contactor open with a clunk sound.
  5. Install the logic connector cap onto the high voltage controller connector to prevent mistaken reconnection and protect the connector.
  6. Remove the bolts (x3) that attach the ancillary bay cover to the high voltage controller.

    The video(s) included in this procedure are meant as an overview for supplemental purposes only. Follow all of the steps listed in the procedure to avoid damage to components and/or personal injury.
    Tip: Use of the following tool(s) is recommended:
    • 4 in extension
    • Ratchet/torque wrench
    • Torque wrench with angle measurement
    • External Torx E10 5-Lobe
    • Cordless Ratchet/Impact Driver
  7. Remove the bolts (x18) that attach the ancillary bay cover to the HV battery.
    Tip: Use of the following tool(s) is recommended:
    • Ratchet/torque wrench
    • 10 in extension
    • External Torx E10 5-Lobe
    • Cordless Ratchet/Impact Driver
  8. Put on HV insulating gloves and leather outer gloves before continuing this procedure.
  9. Remove the ancillary bay cover from the vehicle.
  10. Inspect whether HV insulators are present. If not present or partly present, use the Ancillary Bay Insulator kit and install the insulator caps onto the HV battery to cover live HV points. See Insulators - HV Battery (Remove and Install).
  11. Visually inspect the condition of the ancillary bay cover gasket and the HV battery mating surface for cracks, cuts, gouges, abrasions, or any damage that could affect the seal.
    Informational PurposesAn informational icon, calling your attention
    Note
    If the damage to the gasket is severe, replace the ancillary bay cover. If there is minor damage (including paint) that might affect the seal, perform an ancillary bay air leak test when instructed to do so.

Install

  1. For Europe only: Check the ancillary bay cover that is being replaced for the presence of a recycling warning label that includes a CE marking and manufacturer information.
    Figure 1. 1108781-BB-F shown, 1108781-SH-F similar
    • If the recycling warning label with CE marking and manufacturer information is not present on the ancillary bay cover being replaced, continue to the next step.
    • 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-SH-F) on the new ancillary bay cover.
  2. Use IPA wipes to clean the ancillary bay cover gasket surface, and the mating surface of the HV battery.
  3. Remove all insulator kit covers from the HV battery. See Insulators - HV Battery (Remove and Install).
  4. Position the ancillary bay cover to the HV battery.
  5. Remove the HV insulating gloves.
  6. Install the bolts (x18) that attach the ancillary bay cover to the HV battery.
