So, it looks like you may have a fuse that is blown, I would start by checking all fuses with the ignition system on.

The DTC U0155-87 on a 2024 Toyota Land Cruiser refers to a "Lost Communication with Instrument Panel Cluster (IPC) Control Module – Missing Message."

Here is a guide to help:

Since so much work has been done, I would check the system grounds as well. Here is a guide to help you check the grounds and I have included the liftgate wiring diagrams and I marked the fuses I would check first. Check out the images (below). Please let us know what happens.
