ID Component ID Name Cause Effect Solution
46 Platform
Rotate CW
Valve
12 Circuit
shorted to
V+
PCON detected
that V17PRL
circuit is shorted
to 12 V.
Platform
Rotate CW
function will
not operate.
* With a voltmeter, measure Y70.
Proper resistance should be between 5 -
60 ohms. Replace Y70 if resistance is
outside of those values.
* Verify wiring for V17PRL (GR, PCON
J12-5) and check for open or short
circuits.
15 Circuit
shorted to
GND
PCON detected
that V17PRL
circuit is shorted
to GND.
47 Platform
Rotate CCW
Valve
12 Circuit
shorted to
V+
PCON detected
that V18PRR
circuit is shorted
to 12 V.
Platform
Rotate CCW
function will
not operate.
* With a voltmeter, measure Y71.
Proper resistance should be between 5 -
60 ohms. Replace Y71 if resistance is
outside of those values.
* Verify wiring for V18PRR (GR/BK,
PCON J12-4) and check for open or short
circuits.
15 Circuit
shorted to
GND
PCON detected
that V18PRR
circuit is shorted
to GND.
51 Drive
Forward /
Reverse
Joystick
12 Joystick
voltage too
high.
Circuit C160DRV
is above 4.5 V.
Drive
Forward and
Reverse
functions will
not operate.
* Leave joystick in neutral position and
cycle power.
* If fault persists, with a voltmeter check
that C160DRV (WH/RD, PCON J18-10) is
at 2. 5V +/- 0.2 V at startup and does not
go above 4.5 V or below 0.5 V when fully
stroked in each direction.
* Replace joystick if voltage check fails.
15 Joystick
voltage too
low.
Circuit C160DRV
is below 0.5 V.
19 Joystick
held at
startup.
Circuit C160DRV
voltage was not
within the startup
voltage range of
2.5 V +/- 0.2 V.

TCON detected
that C30FWD
circuit is shorted
to 12 V.
Drive
Forward,
Brake
Release and
possibly
Engine will
not operate.
* With a voltmeter, measure Y6. Proper
resistance should be between 5 -
60 ohms. Replace Y6 if resistance is
outside of those values.
* Verify wiring for C30FWD (WH, TCON
J2-6) and check for open or short circuits.
15 Circuit
shorted to
GND
TCON detected
that C30FWD
circuit is shorted
to GND.

that C31REV
circuit is shorted
to 12 V.
Drive
Reverse,
Brake
Release and
possibly
Engine will
not operate.
* With a voltmeter, measure Y5. Proper
resistance should be between 5 -
60 ohms. Replace Y5 if resistance is
outside of those values.
* Verify wiring for C31REV (WH/BK,
TCON J2-7) and check for open or short
circuits.
15 Circuit
