Are there any diodes in the Toy-10 T-Harness (Toy-2 and TY-20)?

Are there any diodes inside the harness that could go bad?  I am still working on an issue with my 2019 Tundra and just found out that some harnesses have diodes or resistors in them.  I just want to be able to test the harness if the new unit I get still fails to connect to the CAN-BUS.  The TOY-10 consists of 2 harnesses.  TOY-2 and TY-20.

No, not inside Toy-10. Must be careful with this harness, the pin inside TY-20 are tiny and if inserted incorrectly could break.

You can inspect TY-20 connector and make sure all pins are straight.
