Service wasn’t able to troubleshoot the issue, I paid them $120 so they could tell me that I need to spend more $$$ so they can continue to troubleshoot the issue. Useless.

I did remove and put back some fuses some time ago. One of the fuses wasn’t properly put in place and after 2 months started to generate all kind of weird issues with computers. After I paid the service $120 and slept on it I opened the fuse box and rechecked all fuses. One of them was loose. I properly put it back and it solved all problems.

To be completely sure I bought VXDiag Nano Toyota OBD scanner and verified that there were no other issues using Techstream (same software used by lexus service). Computers complained about inability to communicate and causes the warning light.
