or the valve coil is faulty (open) or discon-
nected.
The Flow Direction valve coil is faulty or
disconnected or the coil driver is faulty.
The Swing valve coil is faulty or discon-
nected or the coil driver is faulty.
The Mast valve coil is faulty or discon-
nected or the coil driver is faulty.
The Proportional Relief valve driver output

CHECK
• Check the valve driver output CR3(11) for a short
circuit with -Vbatt.
• Check the valve coil connections and wiring for
interruptions.
• Check the valve coil for correct impedance (refer to
Section 8).
• If the wiring is correct, the driver circuit is damaged
: replace the Slave controller.
• Check the valve coil connections and wiring for
interruptions.
• Check the valve coil for correct impedance (refer to
Section 8).
• Replace the Slave controller if the coil and its har-
ness are correct.
• Check the valve driver output CR3(34) for a short
circuit with -Vbatt.
• Check the valve coil connections and wiring for
interruptions.
• Check the valve coil for correct impedance (refer to
Section 8).
• If the wiring is correct, the driver circuit is damaged
: replace the Slave controller.
• Check the valve coil connections and wiring for
interruptions.
• Check the valve coil for correct impedance (refer to
Section 8).
• Replace the Slave controller if the coil and its har-
ness are correct.
• Check the valve coil connections and wiring for
interruptions.
• Check the valve coil for correct impedance (refer to
Section 8).
• Replace the Slave controller if the coil and its har-
ness are correct.
• Check the valve coil connections and wiring for
interruptions.
• Check the valve coil for correct impedance (refer to
Section 8).
• Replace the Slave controller if the coil and its har-
ness are correct.
• Check the following Slave controller driver output
CR3(23) for a short circuit with +Vbatt.
• Check the valve coil for correct impedance (refer to
Section 8).
• If the harness and the coil are correct and if the fault
appears at start up : Replace the Slave controller.
• Check the valve driver output CR3(23) for a short
circuit with -Vbatt.
• If the wiring is correct, the driver circuit is damaged
: replace the Slave controller.
