Hi we have this Linde R16SN-12 serial H2X115D00968 a 2013 model. 115-03 type
Error T236 sorry
Truck starts ok and drives, and lifts as we turn the steering it throws up this error about steer angle.

We tried calibration of steer unit and steer pot says pot voltage error.
So we replaced the pot and still the same.
The info we were given is that Pot u1 should be about 5.5v and Pot u2 should be about 3.2v when steering is straight. However, the maximum voltage we get it 4.6v and drops off after that cannot get it to 5v or over.
So we assumed the steer unit must be faulty as it most probably supplies the voltage however even after replacing this unit we still cannot get it to calibrate and the voltage will still not go above the 4.6v.
We have also tried the steering wheel pot off another truck. We were told by a linde Engineer that apparently they had issues with the steering loom and a resistor in this loom. Can anyone shed any light on this error or if they have come across this issue about the loom?

We don't know what else to try at the moment.
Please help :)
