if the motor spins when you activate functions and none work and you have lost steering also?
-check your fluid level
-there should be a manifold block with a solenoid on it that enables hydraulic operation when the system is activated, it isn't the function manifold block, this is a single manifold block with a solenoid by itself probably mounted near the steering tiller area. According to the hydraulic schematic it shows this in the system.

Also are there any event codes displaying on the dash display?
that may give you a clue what might be wrong? If anything electrical goes wrong there is usually an even code triggered.
