Correction code 1630010031 1630010032 FRT 0.42 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.

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.
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.

Remove

  1. Open the LH front door and lower the LH front window.
  2. Raise and support the vehicle. See Raise Vehicle - 2 Post Lift.
  3. Remove the rear underhood apron. See Underhood Apron - Rear (Remove and Install).
  4. Disconnect MV power. See Mid-Voltage Power (Disconnect and Connect) (Modify).
  5. Perform Vehicle HV Disablement procedure. See Vehicle HV Disablement Procedure (without Terrestrial Armor) (Test/Adjust).
  6. Disconnect the FDU HV harness from the HV battery.
    CAUTION
    Do not force the release lever up.
    Note
    Release the locking tab and rotate the release lever up to disengage the connector.
    Note
    Make sure the alignment tabs on the FDU header are not damaged.
  7. Remove the bolts (x2) that attach the FDU HV header to the vehicle, and then remove the header from the vehicle.
    10 Nm (7.4 lbs-ft)
    Note
    Slide the header downward to remove it.
    Tip
    Use of the following tool(s) is recommended:
    • EPR10 socket

Install

  1. Position the FDU HV header into the vehicle, and then install the bolts (x2) that attach the header to the vehicle.
    10 Nm (7.4 lbs-ft)
    Note
    Slide the header upwards to position it.
    Tip
    Use of the following tool(s) is recommended:
    • EPR10 socket
  2. Connect the FDU HV harness to the HV battery.
    CAUTION
    Be careful not to damage any pins.
    Note
    Verify the lever is in the upright and open position before connecting. Carefully seat connector and allow the lever to engage. Fully secure the lever and verify the red tab is locked.
  3. Integrate HV power. See Vehicle HV Disablement Procedure (without Terrestrial Armor) (Test/Adjust).
  4. Lower the vehicle until the tires are touching the ground.
  5. Reconnect MV power. See Mid-Voltage Power (Disconnect and Connect) (Modify).
  6. Install the rear underhood apron. See Underhood Apron - Rear (Remove and Install).
