Hi, Maybe someone has info about above code on Hitachi zx350 excavator ,code 20101-02. Customer send to me today I need some starting point to diag the machine. Thank you.
Welcome to HEF Iysy1972 ! Dash number? 20101-02 just means there is an engine warning. I do not know which engine is in that excavator, but you most likely need diagnostic software for that engine manufacturer to see the codes.
