I wish I could help you with that info but it was never published that I know of and the local dealer who built a pump dyno didn't even tell us in the field about that stuff. We did use the travel functions or cycle times on boom up to see if it was working properly.

Fault code 14 is disconnection in swing brake solenoid system. You can get this fault if the swing brake prolix switch is in the full time release position. Fault code 23 is front pump pressure sensor sensor system. It can be a bad sensor or a problem with the wiring. Fault code 26 is the engine speed sensor problem. You can check the sensor with an ohm meter. It should show around 3 to 8 ohms resistance between the wire leaks and no continuity between a lead and the body of the sensor. Good Luck on the repairs.

Thank you, dear sir. Where is the code sensor 23 installed❤

How much is the temperature, diesel and speed screen, used, in good condition, can you send me one to Jordan?

@@user-qv3fi3fd1m As I recall the pressure sensor is installed on the main control valve at the hose connection from the pump. There is a sensor for each pump and valve section and you will see the wires going into each.

@@user-qv3fi3fd1m I'm not in the parts business so I can't send parts to you. You should be able to find them somewhere in North Africa or Europe easy enough. Good Luck

As I recall that monitor panel doesn't have any and you have to plug into the system with the Cat Sys program to view the diagnostics.
