Procedure

  1. Prepare the vehicle for lifting. See GUID-0ECF2493-88F6-48E9-ADBB-9AE1D52E217C.html.
  2. Perform Vehicle HV Disablement Procedure. See Vehicle HV Disablement Procedure.
  3. Remove the rear aero shield panel. See Panel - Aero Shield - Rear (Remove and Replace).
  4. Disconnect the rear drive unit logic connector from the rear drive inverter.
  5. Install the inverter leak test adapter into the rear drive unit logic connector.

    Informational PurposesAn informational icon, calling your attention
    Note
    Make sure that the alignment tabs on the rear drive unit header are not damaged.
  7. Install the other leak test adapter into the rear drive inverter header.
  8. Connect the leak test adapter to the enclosure leak test kit.
  9. Turn the valve knobs to a vertical position to close both valves on the enclosure leak test kit.
  10. Connect the enclosure leak test kit to a compressed air supply line.
  11. Open the inlet valve, and set the regulator to 1 psi.
  12. Open the outlet valve to inject air into the rear drive inverter, and allow 60 seconds for the pressure to stabilize at 1 psi.
  13. Close the inlet valve and wait for 60 seconds for the pressure to settle.
  14. Record the starting pressure, then wait for 45 seconds, and then record the end pressure.
  15. Subtract the ending pressure from the starting pressure, and if:
    • The difference is greater than 0.2 psi, check the hose, adapter, and plug fittings, close the outlet valve and open the inlet valve, check the enclosure leak test kit pressure, and then retest from step 9. If the difference is still greater than 0.2 psi, further investigate possible causes for the pressure leak If the cause for the pressure leak can still not be found and resolved, escalate a Toolbox session.
    • The difference is 0.2 psi or less, continue the procedure.
  16. Disconnect the compressed air supply line from the enclosure leak test kit.
  17. Disconnect the leak test adapter to the enclosure leak test kit.
  18. Remove the leak test adapter from the rear drive inverter.
  19. Install the HV connector lever lock to the rear drive unit HV cable connector.
  20. Align the connector to the rear drive unit, and then remove the HV connector lever lock before fully latching the connector.
  21. Latch the locking tab to connect the rear drive unit HV harness to the rear drive unit.

    Note
    Once connected, verify that the locking tab is not damaged and the rear drive unit HV connector is fully secured in the latched position.
  22. Remove the inverter leak test adapter from the rear drive unit logic connector.
  23. Secure the rear drive unit logic connector to the rear drive inverter.

    CAUTION
    Make sure that there is no coolant ingress in the connector.
  24. Install the rear aero shield panel. See Panel - Aero Shield - Rear (Remove and Replace).
  25. Install the 2nd row seat cushion. See Seat Cushion - 2nd Row (Remove and Replace).
  26. Connect the LV battery power. See LV Battery - Li-lon (Disconnect and Connect).
