Primary Up/Down
Joystick
11
Shorted to
supply
5V
Primary Boom Disabled
Verify:
*5V at JC7-2
(P162PJW OR)
*B- at JC7-1 (JSGND
BR)
*500 to 4500 mV at
JC7-3 & PCON
C46-11 (C195STC BL/
WH) through joystick
motion.
16 Sensor at Zero 0V
17 Not calibrated
Not between 2000
& 3000 mV at
startup
22 Primary Up Valve
25
Resistance Too
High Open Circuit or
Ohms > 60
Associated Function
disabled
*Check Ohms
*Verify no open/short
circuit across
PCON C20-5 BK & B-
(V01PBU RD)
26
Resistance Too
Low Short or
Ohms <5
23 Primary Down Valve
25
Resistance Too
High Open Circuit or
Ohms > 60
Associated Function
disabled
*Check Ohms
*Verify no open/short
circuit across
PCON C20-6 BK & B-
(V02PBD RD/BK)

Primary Boom Angle
Sensor
11
Shorted to
supply
>4850 mV
Act as if in Out of
Stowed
position
*elevated drive speed
*no elevated drive due
to
tilt drive cutout on CE
units
Driving at 2 MPH is
allowed if primary and
secondary
angle sensors are
calibrated
and the mV value is
close to the calibrated,
stowed value.
Verify:
*5V from C27-5 to
C12-C (P109PWR GR/
WH)
*B- at Pin C12-A
*Signal Output
approximately 1000 -
4000 mV across range
of motion at
LRDCON C27-16
(C123 PBS RD/BK)
*Cycle Power with
problem
corrected to clear fault
To Calibrate:
*Stowed mV must be
between 2600 & 3400
mV
*Elevated mV must be
between 400
16 Sensor at Zero 0V
17 Not calibrated
Calibration Not
Completed
19 Out of Range
Reported angle
sensor value out
outside normal
range more than 3
degrees
