  1. 2023-06-19: Removed mention of deprecated EU specific tool.
  • 1076921-00-B Insulation Multimeter, Fluke 1507
  • 1130480-00-A Test Probes, Slim, Fluke TP38
  • 1813553-00-A 5-Way Air Splitter
  • 1140501-00-A Enclosure Leak Test Kit

Procedure

  1. Perform the vehicle electrical isolation procedure. See Vehicle HV Disablement Procedure.
  2. Take off the HV insulating gloves.
  3. Remove and discard the breather from the ancillary bay probe lid cover.
  4. Install the air splitter hose (1813553-00-A) to the ancillary bay probe lid cover.
  5. Remove the mid aero shield panel. See Panel - Aero Shield - Mid (Remove and Replace).
  6. Remove and discard the breather from the RH HV battery vent shroud assembly.
  7. Remove and discard the breather from the LH HV battery vent shroud assembly.
  8. Install the air splitter hoses (x2) to the shroud assembly.
  9. Connect the pack enclosure leak tester (1140501-00-A) to the air splitter.
  10. Close both valves on the pack enclosure leak tester, and then connect a compressed air supply line.
  11. Fully close the pack enclosure leak tester, and then open the inlet valve.
  12. Set the pack enclosure leak tester to 0.15 psi.
  13. Open the outlet valve, and allow at least 45 seconds for the pressure to stabilize to 0.15 psi.
  14. Close the inlet valve, record the starting pressure displayed, and then start a 60-second timer.
  15. After 60 seconds record the ending pressure displayed.
  16. Subtract the ending pressure from the starting pressure, and if:
    • The difference is greater than 0.0023 psi, check the hose, adapter, and plug fittings, close the outlet valve and open the inlet valve, check the regulator pressure, and then retest from step 13. If the difference is still greater than 0.0023 psi, escalate a Toolbox session.
    • The difference is 0.0023 psi or less, continue the procedure.
  17. Disconnect the air supply from the pack enclosure leak tester.
  18. Open the inlet valve, and then disconnect the pack enclosure leak tester from the air splitter in the HV battery shroud assembly.
  19. Remove the air splitter hoses (x2) from the HV battery shroud assembly, and then install new breathers (x2) into the shroud assembly.
  20. Install the mid aero shield panel. See Panel - Aero Shield - Mid (Remove and Replace).
  21. Remove the air splitter hose from the ancillary bay probe lid cover.
  22. Install a new breather into the ancillary bay probe lid cover.
  23. Connect 12V power. See 12V/LV Power (Disconnect and Connect).
