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 IconA warning icon, calling your attention to a possibly risky situation
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
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. Provide corrections and feedback to ServiceDevelopment@teslamotors.com.
Informational PurposesAn informational icon, calling your attention
Note
If the new device cluster has PN 1816026-XX-J or later, the header plug must be replaced with PN 1507801-20-E or later. Refer to HV Harnesses - HV Connector Header, Plug, 300mm2 (Remove and Install) to replace the header plug.

Remove

  1. Inspect the replacement device cluster for the presence of pre-installed pyro disconnects.
    Warning IconA warning icon, calling your attention to a possibly risky situation
    Warning
    Do not install a device cluster with pre-installed pyro disconnects.
    • If the replacement device cluster has no pre-installed pyro disconnects, go to step 7.
    • If the replacement device cluster has any pre-installed pyro disconnects, continue to the next step.
  2. Remove the bolts (x2) that attach the primary pyro disconnect to the device cluster, and then remove the pyro disconnect from the device cluster.
    Tip: Use of the following tool(s) is recommended:
    • 13 mm socket
  3. Remove the bolts (x2) that attach the secondary pyro disconnect to the device cluster, and then remove the pyro disconnect from the device cluster.
    Tip: Use of the following tool(s) is recommended:
    • 13 mm socket
  4. Put the removed pyro disconnects into the service center's parts inventory.
  5. Inspect the orientation of the shunts on the replacement device cluster to confirm both shunts are in the correct position. Refer to the images below for the correct and incorrect orientations.
    Warning IconA warning icon, calling your attention to a possibly risky situation
    CAUTION
    Do not install a new device cluster assembly with either shunt in the incorrect orientation. Installing an assembly with either shunt in the incorrect orientation may result in the vehicle exhibiting unexpected displayed UI range and subpack imbalance issues.

    Figure 2. Incorrect orientation
    Figure 3. Incorrect orientation
    Figure 4. Incorrect orientation
  6. If a shunt is in the incorrect orientation, gently pull the harness end of the shunt upward and away from the device cluster assembly to release it, rotate the shunt to the correct orientation, and then reinstall the shunt into the assembly.
  7. Raise and support the vehicle. See Raise Vehicle - 2 Post Lift.
  8. Remove the tonneau slats. See Slat System - Tonneau (Remove and Install).
  9. Place the vehicle into Service Mode. See Service Mode.
  10. Unlock the vehicle Gateway. See Gateway (Unlock).
  11. Connect a laptop with Toolbox 3 to the vehicle. See Toolbox 3 (Connect and Disconnect).
  12. On the vehicle touchscreen, navigate to Service UI > High Voltage Tab > Procedures > Device Cluster Assembly (DCA) Replacement > Backup Old DCA, and then tap Run to back up the device cluster assembly.
