Jungheinrich ETVQ 25:
error 0802.5 and error 0802.26

Hi we have a truck that has us baffled any pointers would be appreciated. We have been told by a jungheinrich specialist could be software mismatch which would make sense however would be interested in hearing a second opinion.
We had one with this error after judit diagnosing we found the fault identying steer controller in the right leg.
So we moved the controller to the left leg and the fault changed across to left leg.
Customer ordered a new part and fit today and same fault. So he moved controller accross and fault moved accross.

So we assumed it was a supplied faulty controller. However to confirm we had another truck with same part number that works, so took the steer controller off a working truck and that would not work either.

So we know the controller is not faulty but issue is with the controller being fitted. If it is a software incompatible issue how can we get this sorted? IS there a way of ordering part to match that software? I would have thought the working truck controller would have had same software as truck both 2020 and exactly the same.
Any help would be appreciated.
Regards

With such errors, this is a problem with the steering controller.

Hello!

I've been thinking about the issue for few days and I would test CAN circuit before the controller, and after. Actually the steering system is on left/right side ise quite simple. Also open covers for wheel and actual steering angle sensors and swap L & R sensors if possible., we had one full of metallic dust that drove the sensors giving bad signal. But given the errors start with 0, and not 3 the issue would be on the side of combination-controller <-> steering controller. Check the plug pins 2-5(XB 174 PLUG) and XB 175 pins 2-5. Also XB300's no 26 and no 5.
If its matter of software, I would expect encoding related error or error starting with 6.

Software can be patched, but not by service techs.
Given that you failed to provide us s/n of given machine I cannot help to confirm your further suspision of different controller versions.
