DESCRIPTION
The Jib Lift Down valve driver is shorted
or the valve coil is faulty (open) or discon-
nected.
The Jib Lift Down valve coil is faulty or dis-
connected or the coil driver is faulty.
The Jib Lift Down valve coil driver output
is shorted to +Vbatt.
The left brake positive output supply is
detected shorted to -Vbatt.
The EV1 valve driver is not able to drive
the load (cannot close).
The right brake positive output supply is
detected shorted to -Vbatt.
The Steer valve driver is shorted or the
valve coil is faulty (open) or discon-
nected.

CHECK
• Check the valve driver output CR3(33) 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
short to +Vbatt.
• Check the valve coil for correct impedance (refer to
Section 8).
• Check the left brake positive driver output CR3(2)
for a short circuit with -Vbatt.
• Check the brake coil for correct impedance (refer to
Section 8).
• If the wiring and the coil are correct, the driver cir-
cuit is damaged : replace the Slave controller.
• The device or its driving circuit is damaged, replace
the controller.
• Check the right brake positive driver output CR2(2)
for a short circuit with -Vbatt.
• Check the brake coil for correct impedance (refer to
Section 8).
• If the wiring and the coil are correct, the driver cir-
cuit is damaged : replace the Master controller.
• 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.
