Procedure

1. Remove the mid aero shield panel. See Panel - Aero Shield - Mid (Remove and Replace).

2. Remove and discard the breather from the RH HV battery vent shroud assembly.

3. Install the leak test adapter plug into the RH shroud assembly.

4. Remove and discard the breather from the LH HV battery vent shroud assembly.

5. Install the leak test adapter into the LH shroud assembly.
6. Connect the pack enclosure leak tester to the leak test adapter in the LH HV battery shroud assembly.
7. Close both valves on the pack enclosure leak tester, and then connect a compressed air supply line.
8. Fully close the regulator, and then open the inlet valve.
9. Set the regulator to 0.15 psi.
10. Open the outlet valve, and allow at least 45 seconds for the pressure to stabilize to 0.15 psi.
11. Close the inlet valve, record the starting pressure displayed, and then start a 60-second timer.
12. After 60 seconds record the ending pressure displayed.
13. Subtract the ending pressure from the starting pressure, and if:

• The difference is greater than 0.0054 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 10. If the difference is still greater than 0.0054 psi, escalate a Toolbox session.
• The difference is 0.0054 psi or less, continue the procedure.

14. Disconnect the air supply from the pack enclosure leak tester.
15. Open the inlet valve, and then disconnect the pack enclosure leak tester from the leak test adapter in the LH HV battery shroud assembly.
16. Remove the leak test adapter from the LH HV battery shroud assembly, and then install a new breather into the LH shroud assembly.
17. Remove the leak test adapter plug from the RH HV battery shroud assembly, and then install a new breather into the RH shroud assembly.
18. Install the mid aero shield panel. See Panel - Aero Shield - Mid (Remove and Replace).
