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.

Procedure

  1. Move the vehicle to a 2-post lift. See Raise Vehicle - 2 Post Lift.
  2. Remove the rear underhood apron. See Underhood Apron - Rear (Remove and Replace).
  3. Disconnect LV power. See LV Power (Disconnect and Connect).
  4. Remove the mid aero shield panel. See Panel - Aero Shield - Mid (Remove and Replace). .
  5. Carefully remove the gore breathers (x4) from the breather assembly at the rear of the HV battery pack.
  6. Insert tapered plugs into three breather holes so that they fit snugly.

    CAUTION
    Do not push plugs too far inside.
  7. Install the leak test adapter into the fourth breather hole.
  8. Connect the enclosure leak tester hose to the leak test adapter.

    Note
    Restrain the enclosure leak tester hose so that it will not tug the leak test adapter out of the HV battery.
  9. Turn valve P2 (left) and valve P1 (right) to the closed (vertical) position on the enclosure leak tester.
  10. Turn the knob on the regulator to the fully closed setting.
  11. Connect the supply compressed air line to the enclosure leak tester.
  12. Turn valve P1 (right) to the open (horizontal) position and slowly adjust the regulator so that 0.3 psi is displayed on the gauge.
  13. Make sure that the regulator is set to 0.3 psi.
  14. Slowly turn valve P2 (left) to the open (horizontal) position and allow air to enter the HV battery.
  15. Allow 60 seconds for the pressure to stabilize.
  16. Turn valve P1 (right) to the close (vertical) position.
  17. Record the beginning pressure value and start a 30 second timer.
  18. After 30 seconds has elapsed, record the end pressure value, and then substract the end pressure value from the beginning pressure value.
    • If the pressure difference is more than 0.026 psi, inspect the HV battery for leaks, turn valve P2 (left) to the close (vertical) position, and retest from step 12.
    • If the pressure difference is 0.026 psi or less, continue to the next step.
  19. Disconnect the supply compressed air line from the enclosure leak tester.
  20. Slowly turn valve P1 (right) to the open (horizontal) position, and allow air to exit the HV battery.
  21. Disconnect the enclosure leak tester hose from the leak test adapter.
  22. Remove the leak test adapter from the fourth breather hole.
  23. Remove the tapered plugs from the three breather holes.
  24. Carefully install the gore breathers (x4) into the breather assembly at the rear of the HV battery pack.
