Repairman,
when it quits do you see any codes displayed on the dash display?
Also when the key is turned off you can press the star key (first button from the left) and it will flash any stored codes. There are 16 code slots per controller, first will be drive controller codes and then it will pause and then display the hydraulic controller codes.
Now for some reason if it does not go into the hydraulic error codes using the star key then press the last key on the right side.

If you want more detailed information like hour meter per code you'll need to hook up the laptop to it and pull the fault codes that way. The display only shows the error code and its description only.
