You may have a wiring issue. Does the code say "RTF valve shorted to high/low source"?
Locate the RTF valve (your case tech should be able to find that, its hard to describe location), follow wiring up paying attention to places where the wiring loom was zip tied to hydraulic lines. Vibration of the loom will wear into and damage the small wires. Had this happen to our 7120, same symptoms you describe. I can get pictures tommorow of the valves location and the exact spot the wires were chaffed.
