Remarque
Cette procédure nécessite que la procédure de récupération et de recharge du fluide frigorigène de climatisation soit effectuée. S'il n'est pas déjà ajouté automatiquement à la visite de service, ajoutez le code de correction 18200102 en tant que correction distincte de la même activité à la visite d'entretien.

Procédure

  1. Set up the A/C machine.
  2. Remove the underhood storage unit. See Underhood Storage Unit (Remove and Replace).
  3. Unlock the vehicle gateway. See Déverrouillage de passerelle.
  4. On the touchscreen, touch Service Mode > Thermal > Refrigerant System > Start Refrigerant Fill/Drain and select Run to start the "Start Thermal Fill Drain (Refrigerant Only)" routine.
  5. Recover the A/C refrigerant. See A/C Refrigerant (Recovery and Recharge) (Restore).
  6. Perform the vacuum leak test and refill A/C refrigerant. See A/C Refrigerant (Recovery and Recharge) (Restore).
  7. Add 5 ml UV dye.
    Remarque
    Add the dye with the refrigerant and oil.
  8. Remove the A/C hoses from the vehicle.
  9. On the touchscreen, touch Thermal > Refrigerant System > Run Heat Pump Commissioning and select Run to start the routine.
  10. Touch Thermal > Actions > Test Thermal Performance and select Run to start the routine.
    Remarque
    Make sure the routine is passed, then touch Close to close it.
  11. Touch Thermal > Actions > Test HVAC Performance and select Run to start the routine.
    Remarque
    Make sure the routine is passed, then touch Close to close it.
  12. Exit Service Mode through UI. See Mode Entretien.
  13. Set the temperature to LO on both driver and passenger HVAC controls and set the A/C system to AUTO.
  14. Run the A/C system for 10 minutes to allow the dye to circulate.
  15. Use UV light and the UV inspection kit to check for A/C refrigerant leaks near the HVAC end of the Supermanifold to HVAC A/C line.
    Remarque
    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 A/C low and high pressure port.
    Remarque
    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).
  17. Use UV light and the UV inspection kit to check for A/C refrigerant leaks at the supermanifold area.
    Remarque
    If an A/C refrigerant leak is found, replace the defective component.
  18. 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.
    Remarque
    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).
  19. Use UV light and the UV inspection kit to check for A/C refrigerant leaks on the supermanifold.
    Remarque
    If an A/C refrigerant leak is found, replace the defective component.
  20. Remove the front aero shield. See Panel - Aero Shield - Front (Remove and Replace)
  21. Use UV light and the UV inspection kit to check for A/C refrigerant leaks near the Supermanifold end of the Supermanifold to HVAC A/C line.
    Remarque
    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).
  22. Install the front aero shield. See Panel - Aero Shield - Front (Remove and Replace)
  23. Install the caps (x2) back onto the A/C ports.
  24. Install the underhood storage unit. See Underhood Storage Unit (Remove and Replace).
