jungheinrich efg no pump connection alarm 34

We have a jungheinrich efg using the mp 616k controller. Everything works fine even the hydraulic yet on the display it states no pump connection alarm 34. We purchased this controller and fit to our truck which originally had hydraulic problems where it would blow the controller. At present we have left display disconnected but would be nice to get to the bottom of it. Has anyone encountered this issue?

regards

I will get the serial next week for you. It uses Jungheinrichs own MP616k controller its a combi traction sepx ex controller with a series pump.
The truck works fine with or without the display. However if we connect the display up it appears on the display Alarm 34 no pump connection.

It was a controller purchased and fit onto a truck that did not have a controller due to the original control system being blown by the engineer whilst working on it during servicing I think.
