Problem solved, there were two SMD capacitors burned in the LSM, I bought one from a scrapyard 75 and it is now solved, I just have to set it to TOAF. At first I had an error in the box, which is normal, but now the error has disappeared on its own, I will still check that it is linked correctly with the other modules.
The license plate light has symptoms of some water having entered, I have disassembled it, converted it to LED and sealed it completely for safety.
Mike Noc, xsport & SD1too, thanks you very much for trying to help me!
