System Fault: Hydraulic Valve Disconnected!
This pop-up will display when the system ECU detects that one of the water valves is disconnected. The
ECU applies a small voltage to the solenoid coil of the hydraulic valve installed in the hydraulic manifold. If
it measures a current within a certain range, it detects that the hydraulic valve is connected properly. If it
does not detect a return current flow, it will activate a VALVE DISCONNECTED fault. There are (3) water
control valves in the system: Upper Boom, Lower Boom and Board Spray.
