    Note
    The test will last for approximately 10 minutes. Monitor and keep the superbottle topped off while the test is running. Coolant pump speeds can be monitored in Service Mode + (see Service Mode Plus), in the CAN Viewer submenu. If pump speeds stay above 6900 rpm, there is still air entrapped in the system; run a cooling system vacuum refill.
  11. When the air purge is complete, top off the superbottle, and then install the superbottle cap.
  12. Disconnect the laptop from the vehicle.
  13. Power off the vehicle from the touchscreen.
  14. Remove the 12V charger from the 12V auxiliary battery terminals or disconnect the LV maintainer from the vehicle. See LV Maintainer (Connect and Disconnect).
  15. Depending on the vehicle configuration, choose one of the following:
    • If the vehicle is equipped with a lead-acid 12V auxiliary battery, disconnect the 12V auxiliary battery negative terminal.
    • If the vehicle is equipped with a Li-ion LV auxiliary battery, disconnect the LV battery connector from the LV battery.
  16. Inspect and put on PPE including the HV insulating gloves and leather over gloves.
  17. Release the bungee strap from the high voltage controller and rear RH seat headrest, and then lower the controller into the ancillary bay.
  18. Measure the voltage across the pyrotechnic battery disconnect mount points, and then install the pyrotechnic battery disconnect. See Pyrotechnic Battery Disconnect (Remove and Replace).
  19. Install the ancillary bay cover. See Cover - Ancillary Bay (Remove and Replace).
  20. Remove the leather over gloves and the HV insulating gloves.
  21. Install the 2nd row lower seat cushion. See Seat Cushion - Lower - 2nd Row (Remove and Replace).
  22. Connect 12V/LV power. See 12V/LV Power (Disconnect and Connect).
  23. Perform a software CAN redeploy. See Software Reinstall - Toolbox.
  24. After the software CAN redeploy is complete, remove the 12V charger from the 12V auxiliary battery terminals or disconnect the LV maintainer from the vehicle. See LV Maintainer (Connect and Disconnect).
  25. Install the cabin intake duct. See Duct - Cabin Intake (Remove and Replace).
  26. Install the rear apron. See Underhood Apron - Rear (Remove and Replace).
