    注
    • 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.

    注
    If an A/C refrigerant leak is found, replace the A/C line from supermanifold to HVAC. See 空调管路总成，歧管至 HVAC ((拆卸和更换)).
  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
    注
    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
    注
    If an A/C refrigerant leak is found, replace the supermanifold to compressor A.C line. See 空调管路总成，超级歧管至压缩机 ((拆卸和更换)).
  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 维护模式.
  21. Install the underhood storage unit. See 前备箱总成 ((拆卸和更换)).
