Warning

Only technicians who have completed all required certification courses are permitted to perform this procedure. Tesla recommends third party service provider technicians undergo equivalent training before performing this procedure. For more information on Tesla Technician requirements, or descriptions of the subject matter for third parties, see HV Certification Requirements. Proper personal protective equipment (PPE) and insulating HV gloves with a minimum rating of class 0 (1000V) must be worn at all times a high voltage cable, busbar, or fitting is handled. Refer to Tech Note TN-15-92-003, High Voltage Awareness Care Points for additional safety information.

CAUTION

Thermal management components operate under very tight specifications and can malfunction if Service procedures are not carefully followed. DO NOT rely on past experience with other thermal management systems; read through the Service Manual and do not deviate from the instructions.

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 correction within the same activity to the Service Visit.

Note
