2012 Volvo ec160c L

I have a 2012 volvo excavator ec160c L and it gave a fault code psid 216-09 that tells me that theres missing information from the i-ecu. It lets me turn it on and while the code is there doesn’t let me move it or anything just rev it, but i reset it and lets me work for a few before stopping and showing me the code. I have options of what could be between the safety lever or a wire malfunction between the i-ecu and monitor or even all together but i still need the help
