Note
This procedure requires the A/C Refrigerant (Recovery and Recharge) procedure to be performed. If not already automatically added to the Service Visit, add correction code 18200102 as a separate activity to the Service Visit.

Procedure

  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 Gateway Unlock.
  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) (Maintenance).
  6. Perform the vacuum leak test and refill A/C refrigerant. See A/C Refrigerant (Recovery and Recharge) (Maintenance).
  7. Add 5 ml UV dye.
