Control System Fault Codes
Part No. 1288652GT S ® -60/65 XC ™ • S ® -60/65 HF • S ® -60/65 TraX ™ 115
ID Component ID Name Cause Effect Solution
54 Brake
Release
Valve
12 Circuit
shorted to
V+
TCON detected
that C32BRK
circuit is shorted
to 12 V.
Machine will
not be
functional.
* With a voltmeter, measure Y2. Proper
resistance should be between 5 -
60 ohms. Replace Y2 if resistance is
outside of those values.
* Verify wiring for C32BRK (WH/RD,
TCON J2-9) and check for open or short
circuits.
15 Circuit
shorted to
GND
TCON detected
that C32BRK
circuit is shorted
to GND.
55 Motor Stroke
Valve
12 Circuit
shorted to
V+
TCON detected
that C29MS
circuit is shorted
to 12 V.
Drive
functions will
not operate.
* With a voltmeter, measure Y27.
Proper resistance should be between 5 -
60 ohms. Replace Y27 if resistance is
outside of those values.
* Verify wiring for C29MS (RD/WH, TCON
J2-8) and check for open or short circuits.
15 Circuit
shorted to
GND
TCON detected
that C29MS
circuit is shorted
to GND.
61 Steer
Joystick
12 Joystick
voltage too
high.
Circuit C159STD
or C159STA is
above 4.5 V.
Drive and
steer
functions will
not operate.
* Leave joystick in neutral position and
cycle power.
* If fault persists, identify which circuit is
the steer circuit. Check C159STA
(BL/WH, PCON J18-11) for a joystick
steer option. Check C159STD (BL/RD,
PCON J18-9) for the rocker joystick steer
option. With a voltmeter check that the
circuit 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 C159STD
or C159STA is
below 0.5 V.
19 Joystick
held at
startup.
Circuit C159STD
or C159STA
voltage was not
within the startup
voltage range of
2.5 V +/- 0.2 V.
68 Safety
Envelope
Fault
21 Out of
range
The system has
determined that
the platform
position has
exceeded the
safety envelope
boundary.
All functions
will not
operate
except for
the recovery
procedure.
Use Auxiliary Power and the boom retract
and/or down functions to bring the
platform back within the operational
envelope.
69 Generator
Control
Circuit
12 Circuit
shorted to
V+
TCON detected
that C45GEN
circuit is shorted
to 12 V.
Generator
function will
not operate.
* With a voltmeter, measure Y29.
Proper resistance should be between 5 -
60 ohms. Replace Y29 if resistance is
outside of those values.
* Verify wiring for C45GEN (GR/WH,
TCON J3-2) and check for open or short
circuits.
15 Circuit
shorted to
GND
TCON detected
that C45GEN
circuit is shorted
to GND.
