Chiller (Remove and Replace)

Correction code 18401602 1.14NOTE: Unless otherwise explicitly stated in the procedure, the above correction code and FRT reflect all of the work required to perform this procedure, including the linked procedures. Do not stack correction codes unless explicitly told to do so.NOTE: See Flat Rate Times to learn more about FRTs and how they are created. To provide feedback on FRT values, email LaborTimeFeedback@tesla.com. NOTE: See Personal Protection to make sure wearing proper PPE when performing the below procedure.

  • 2024-10-24: Updated the removal/installation steps, added the UI routines and added note on adding correction code for refrigerant recovery/recharge 18200102 as a separate activity to the service visit.
