power back door is not open by pressing the switch on the liftgate. PBD switch (left of dashboard) and remote key switch are able to open the liftgate. This is an armored vehicle and additional fittings like sirens and lights are installed. Pls let me know your suggestions. Pls let me know the wiring diagram and location of the control unit, fuses and relay.

Thank you.

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.
