Hello yellowfin

I guess the Controller cannot establish CAN communication with the steer handle card.

The symphtomps would be the following: Traction and hydraulic systems not operate.

I am from Europe and as long as I know some of the truck are different here, but I guess the error code should mean the same. Anyway here it looks like this MPE060F (B896). I hope that is your truck.

Check the connection between the steer handle card and the traction controller. If you have a chance and a spare steer handle card or traction controller just replace it and try it.

I hope it helps.

Good luck
