So your RLSS is red in ISTA and this was a new one from the dealership which was initialized. We're is that fuse located. In the trunk or glove compartment. Did the fuse burn again. If so it's definitely a wiring issue

Its in a trunk right side.
All 3 wires (Ground, +12,LIN bus) at RLSS connector is not shorted and dont have resistance between them, not shorted to ground, circuit is also ok.

One more think does not match in ISTA control unit tree. My RLSS is connected to the car on LIN bus, but in ISTA it appears like its connected via CAN , why?
On pre LCI cars yes, this will be correct, they got older (square) type LM and older type RLS, that was connected via CAN. I found theards on other forums that guys is retrofiting LM2 instead LM to get more functions and leave older type (square) RLS. In this situation they get same fault code in LM module. They wrote that solution to get rid of fault, is upgrade RLS to newer one, or code it out.
Add picture. Of my control unit tree.
