Welcome to HEF gardener2020;)!

First we need a complete machine serial number for accurate information gathering. There are 12-13 variations of that machine.

Code comes up because it is the TCU switched power fuse. That fuse also supplies voltage to other items, transmission related. Obviously, a short somewhere in the circuitry is the issue. Now it is just trying to find it.
