Part No. 1285307GT
ID Component ID Name
Cause
Effect
Solution
74 Engine
Temperature
15 Sensor
value too
low
Engine
temperature
sensor is shorted
to ground
Engine will not
operate
* With a voltmeter, check that
C26TSR ( WH/RD, TCON J6P8) is
not shorted to ground and voltage is
between 0.1-11.5V
* Replace sensor if necessary
23 Too high The engine coolant
temperature is
measured as too
high, potentially
damaging the
engine.
Engine will not
restart until machine
power is cycled.
Engine may stop
itself, depending on
the engine option.
* Stop engine as soon as possible.
* Verify the engine coolant level.
* Verify the engine coolant/water
pump.
* Power on the machine and start the
engine. At the ground controls
display, view the engine temperature
gauge for proper operation.
* If engine uses an analog
temperature sensor, verify it is
sending an analog voltage on
C26TSR (WH/RD, TCON J6-10).
76 Platform
Load Sensor
13 Not
detected
TCON has not
detected the
DISCON on the
communications
bus.
Boom Up, Extend
and Turntable Rotate
functions will not
operate.
* Verify sensor power P26PWR (BK,
PCON J13-9) is at 12 V while the
system is running.
* Verify 12 V across pins on C27-2
(+) and C27-3 (-) on the harness
connector.
* Measure resistance across
C27 pins 4 and 5 on the harness
connector. If resistance is not
between 55 and 65 ohms, check
CAN wire harnesses.
* Replace sensor if necessary.
14 Cross
check
failed
TCON has not
detected the
DISCON on the
communications
bus.
Boom Up, Extend
and Turntable Rotate
functions will not
operate.
* Check that the load sensor is
mounted correctly and all fasteners
are tightened to spec.
* Calibrate load sensor.
* Replace sensor if issue persists.
15 Value to
low
Platform load
sensor out of
calibration
Machine limited to
recovery functions
* Make sure the platform is not
touching the ground or an overhead
obstruction. Cycle power and check
that fault is no longer reported.
* Perform the platform overload
calibration procedure.
* Replace sensor if necessary.
17 Not
calibrated
Platform load
sensor out of
calibration
* Calibrate load sensor.
* Replace sensor if issue persists.
21 Fault
Platform load
sensor out of
calibration
* Check that the load sensor is
mounted correctly and all fasteners
are tightened to spec.
* Calibrate load sensor.
* Replace sensor if issue persists.
