Hi Mishek
You will not get any more info from the controller other than the fault message.
I suspect you have a steering fault, check steering pot and wiring.
Alarm traction 28 reads "Cable break steering sensor"
"Check cable connection; exchange steering wheel sensor; exchange Canion / Interface; exchange steering"
If the steering has a serious fault, the truck will not allow drive to operate.
Hope this helps you
Good luck
