Procedure

  1. Set up the A/C machine.
  2. Open the LH front door.
  3. Remove the underhood storage unit. See Underhood Storage Unit (Remove and Replace).
  4. Unlock the vehicle gateway. See Gateway Unlock.
  5. Recover the A/C refrigerant. See A/C Refrigerant (Recovery and Recharge) (Maintenance).
    Informational PurposesAn informational icon, calling your attention
    Note
    The A/C oil type is ND-11 oil.
  6. Perform the vacuum leak test and oil injection. See A/C Refrigerant (Recovery and Recharge) (Maintenance).
    Informational PurposesAn informational icon, calling your attention
    Note
    Set the vacuum time to 15 min and the leak test to ON.
  7. Tap Next to recharge the A/C refrigerant.
    Informational PurposesAn informational icon, calling your attention
    Note
    • The refrigerant amount and the oil amount should be the same as recorded.
    • Use the Dye Inject option to inject the leak detection dye.
  8. Tap Next to start the "End of Charge" process.
  9. When prompted, close the high and low valves on the machine.
  10. On the touchscreen, tap the Service Mode "wrench" (at the bottom of the touchscreen UI), and then tap Thermal > Refrigerant System > Stop Thermal Fill Drain to stop the thermal fill drain.
  11. Remove the A/C hoses from the vehicle.
  12. Set the temperature to LO on both driver and passenger HVAC controls and set the A/C system to AUTO.
  13. Run the A/C system for 10 minutes to allow the dye to circulate.
  14. Use UV light and the UV inspection kit to check for A/C refrigerant leaks from the AC line assembly to HVAC assembly.

    Note
    If an A/C refrigerant leak is found, replace the A/C line from supermanifold to HVAC. See Assembly - A/C Line - Supermanifold to HVAC (Remove and Replace).
  15. Use UV light and the UV inspection kit to check for A/C refrigerant leaks at the A/C low and high pressure port.
    Informational PurposesAn informational icon, calling your attention
    Note
    If an A/C refrigerant leak is found, replace the A/C line from supermanifold to HVAC. See Assembly - A/C Line - Supermanifold to HVAC (Remove and Replace).
  16. Use UV light and the UV inspection kit to check for A/C refrigerant leaks at the supermanifold area.
    Informational PurposesAn informational icon, calling your attention
    Note
    If an A/C refrigerant leak is found, replace the detective component.
  17. Use UV light and the UV inspection kit to check for A/C refrigerant leaks on the A/C compressor discharge and suction lines area.
    Informational PurposesAn informational icon, calling your attention
    Note
    If an A/C refrigerant leak is found, replace the supermanifold to compressor A.C line. See Assembly - A/C Line - Supermanifold to Compressor (Remove and Replace).
  18. Install the caps (x2) back onto the A/C ports.
  19. Perform the "Heat Pump Thermal System Commissioning", "Thermal System Performance Test", and "HVAC System Performance Test" routines by using the touchscreen.
    1. Tap the Service Mode "wrench" (at the bottom of the touchscreen UI), and then tap Thermal > Action.
    2. Tap the START button next to the corresponding routine, and then tap Run.
    3. Close the pop-up window once the routine has passed.
  20. Disable Service Mode. See Service Mode.
  21. Install the underhood storage unit. See Underhood Storage Unit (Remove and Replace).
  22. Close the LH front door.
