Ferrite Core - Device Cluster Assembly (Installation)

Correction code 16300105726 FRT 0.12 NOTE: Unless otherwise explicitly stated in the procedure, the correction code and its associated 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. NOTE: See Personal Protection to make sure you are wearing proper PPE when performing the procedure below. NOTE: See Ergonomic Precautions for safe and healthy working practices.

  • 2026-02-27: Added steps to remove DCA splash shield for more space to install ferrite core.
  • 2026-01-21: Added ferrite core part number.
Warning
DO NOT SKIP the steps to remove the tonneau slats. Work on or around the ancillary bay REQUIRES the removal of the tonneau slats. Failure to remove the tonneau slats while working on or around the ancillary bay will result in conditions that may cause personal injury.
Warning
Cybertruck electronics are powered by a 48V "mid voltage" or "MV" architecture that is designed to improve efficiency. Servicing MV components requires extra knowledge and care in order to avoid personal and/or vehicular harm. Read and understand MV precautions in Electrical Precautions and make sure any required MV-related training courses have been completed, as applicable.
Warning
Only technicians who have been trained in High Voltage Awareness and have completed all required certification courses (if applicable) are permitted to perform this procedure. 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 glove and safety information.
Warning
This procedure is a DRAFT. Although it has been validated, Warnings and Cautions might be missing. Follow safety requirements and use extreme caution when working on or near High Voltage systems and components.
Note
This procedure should only be performed when installing a new power conversion system on device cluster assemblies that do not already have the ferrite core installed.

  • 2134590-00-A - CTSB, ANC, FERRITE T75 ROUND CABLE CORE ASSEMBLY

Install

  1. Lift the device cluster header seal to access the HVIL electrical connector, release the clip that attaches the connector to the vehicle, and then disconnect the electrical connector.
  2. Slide the device cluster header off the DC bus links.
  3. Disconnect the device cluster harness yellow electrical connector.
  4. Release the clips (x2) that attach the DCA splash shield to the DCA, and then remove the splash shield from the DCA.
  5. Measure 129mm from the base of the device cluster harness yellow electrical connector, and then mark the harness with a marker.
  6. Align the top of the ferrite core at the marked location on the device cluster harness, and then install the ferrite core.
  7. Wrap the ferrite core with a single piece of felt tape as described below.
    • 2 wraps at the base of the ferrite core
    • 5-7 wraps over the ferrite core body
    • 2 wraps at the top of the ferrite core
  8. Position the DCA splash shield to the DCA, and then engage the clips (x2) that attach the splash shield to the DCA.
  9. Connect the DCA harness yellow electrical connector.
  10. Position the DC header onto the device cluster assembly.
  11. Connect the HVIL electrical connector, and then secure the clip that attaches the connector body to the device cluster assembly.
