Hello, the machine is Lift the Cab.

I continuos with this problem, when i move the ignition switch to on possition, the machine show the code 7., this code reffer to Electronic Sterring Controller A3. But the sterring system in the machine is Enable, but the auxiliary functions of hydraulics and traction systems is disable.

¿Is possible, the A3 controller is failed although the direcction is enable? or in the connection in middle of A3 and A2 controller is the problem?

Thanks you
Sorry for my bad english
