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.

  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.

Install

  1. Install the device cluster assembly, but perform the following steps after the installation of the "mid aero shield" but before "connect MV power." See Device Cluster Assembly (Remove and Install).
    1. Connect the MV battery maintainer, but leave the MV battery disconnected: Attach the positive terminal to jump post, and then attach the negative terminal to the bolt located between the brake fluid reservoir and the front trunk.
    2. Connect the MV battery maintainer to power supply.
