ID Component ID Name Cause Effect Solution
96 Engine Oil
Pressure
21 Value too
low
The engine oil
pressure is
measured as too
low, potentially
damaging the
engine.
Engine may
not attempt
to start until
system
power cycle.
Engine may
be turned off
by control
system
immediately.
* Stop engine as soon as possible.
* Verify the engine oil level.
* Verify the engine oil pump.
* Power on the machine and start the
engine. At the ground controls display,
view the engine oil pressure gauge for
proper operation.
* If engine uses an analog oil pressure
sensor, verify it is sending an analog
voltage on C25PSR (WH/BK, TCON J6-9).
100 Platform

12 Circuit
shorted to
V+
PCON detected
that V14PLU
circuit is shorted
to 12 V.

Level Down
functions will
not operate.
* With a voltmeter, measure Y20. Proper
resistance should be between 5 - 60
ohms. Replace Y20 if resistance is
outside of those values.
* Verify wiring for V14PLU (OR, PCON
J12-6) and check for open or short circuits.
15 Circuit
shorted to
GND
PCON detected
that V14PLU
circuit is shorted
to GND.

PCON detected
that V15PLD
circuit is shorted
to 12 V.
Platform
Level Down
and possibly
Level Up
functions will
not operate.
* With a voltmeter, measure Y19. Proper
resistance should be between 5 - 60
ohms. Replace Y19 if resistance is
outside of those values.
* Verify wiring for V15PLD (OR/BK, PCON
J12-7) and check for open or short circuits.
15 Circuit
shorted to
GND
PCON detected
that V15PLD
circuit is shorted
to GND.

This is a flag that
indicates that the
platform was
overloaded and
that auxiliary

Power up the machine in service mode
and clear the flag in the service menu on
the ground control display.

12 Circuit
shorted to
V+
TCON detected
that C3PBF circuit
is shorted to 12 V.
Boom Up
and Down
functions will
not operate.
* With a voltmeter, measure Y12. Proper
resistance should be between 5 - 60
ohms. Replace Y12 if resistance is
outside of those values.
* Verify wiring for C3PBF (RD/WH, TCON
J4-4) and check for open or short circuits.
* Verify resistance between Recovery
Module pins J37-3 and J37-10 is zero
ohms.
15 Circuit
shorted to
GND
TCON detected
that C3PBF circuit
is shorted to
GND.
