Fault Condition/Trigger
(For configurable items, fault applies only if
configured. All listed conditions to be met
unless stated otherwise)
1 Machine is in Platform Mode;
The UGM determines no problems exist
1 Machine is in Ground Mode;
The UGM determines no problems exist
1 Machine is in the Out of Transport position
1 Machine is in Platform Mode;
Any of the following Platform inputs become active
after power up, but before Machine Enabled:
Drive joystick is not in the neutral position
Steer;
Lift and/or Swing joystick is not in the neutral position;
Tower Lift (340AJ, 450AJ);
Telescope;
Platform Level;
Platform Rotate;
Jib Lift (if MACHINE SETUP > JIB = YES)
1 Machine is in Platform Mode;
Platform Creep switch input = HIGH;
DTC 0013 is not active
1 Machine is in Platform Mode;
The Boom is Above Elevation;
Machine chassis is considered Tilted
LSS has been calibrated and the UGM has determined
that the load sensing system reading is less than -50lbs
for 2 seconds. If the load sensing system determines
that the reading is greater than -50lbs for 5 seconds this
fault will no longer be annunciated.
No control system interlocks present when DTC is
active.
Engine Shutdown has occurred due to Fuel Level =
EMPTY condition.
Auxiliary Power/Emergency Descent Mode is active

Assignment
No response required for
this DTC
No response required for
this DTC
Response described in Machine is not in the Out of Transport posi-
Drive Modes section tion
The UGM shall not Enable Controls initialized
the Machine
The UGM shall limit the Platform Creep switch input = Low
machine to Creep speed
The UGM shall limit the Not all of the trigger conditions are met
machine to Creep speed;
If MACHINE SETUP > TILT
= (angle) + CUT, response
described in Tilted Output
Cutouts section
Ensure platform is not resting on the ground
or is not leveled at an extreme negative
angle.
Re-calibrate the load sensing system if the
above items are not a factor.
