Hello, thank you very much for your response, I was able to resolve it, I had to enter with Judit as a forklift from 2016 onwards and there was an option to detect mast elevation. This truck does not have that sensor. I have disabled it and it runs now. The truck reset itself involuntarily. Now the problem I have is that the scroller does not work. I measure the voltage of the solenoid valves and there is no current but the trigger does give a signal in Judit. It still doesn't give any errors and I don't know how to activate the displacer.
