Table 6-17. Diagnostic Trouble Codes
DTC Cat DTC Num DTC Text Fault Description Solution
00 1 EVERYTHING OK The UGM determines that platform station (EVERY-
TING OK)
OR ground station (GROUND MODE OK) is selected
and no system faults exist, including Power Module
check; 0 (No Fault)
Occurrence of active DTC
00 2 GROUND MODE OK The normal help message in Ground Mode. Dis-
plays on the analyzer only.
Ground Mode selected;
& occurrence of active DTC
00 8 FUNCTIONS LOCKED OUT - SYSTEM POWERED
DOWN
Conditions exist and time for automatic power-
down has expired.
Power c ycled
00 10 RUNNING AT CUTBACK - OUT OF TRANSPORT
POSITION
Machine is in the Out Of Transport Position Machine is not Out of Transport;
If Swung, DOS transition requirements are
re qu ir ed to re tu rn to In Li ne speed
00 11 FSW OPEN 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 neu-
tral position;
Tower Lift;
Telescope;
Platform Level;
Platform Rotate;
Jib Lift (if MACHINE SETUP -> JIB = YES);
Jib Swing (if MACHINE SETUP -> JIB PLUS = YES);
Controls initialized
00 12 RUNNING AT CREEP - CREEP SWITCH OPEN Machine is in Platform Mode;
Platform creep switch input = HIGH;
Fault RUNNING AT CREEP – TILTED AND ABOVE
ELEVATION (DTC0013) is not active
Platform creep switch input = Low
00 13 RUNNING AT CREEP - TILTED AND ABOVE ELE-
VATION
Machine is in Platform mode;
Machine is Above Elevation and Tilted;
MACHINE SETUP-> TILT (not + CUT)
Not all of the trigger conditions are met;
Then non-Creep function speed permitted after
controls initialized
00 33 TRACTION MOTOR AT CURRENT LIMIT Machine is in Platform Mode and UGM detects
that Traction Current reported by any Power Mod-
ule > 270A for 3000ms;
MTM or SPM will keep the Traction motor current
below limit (280A@48V) but will not report fault;
Currents return to levels below trigger level for
same time period as trigger;
UGM shall remove Creep speed restriction after
controls initialized
00 36 FUNCTION PREVENTED - FUNCTION SELECTED
BEFORE GROUND ENABLE
Machine is in Ground Mode (DTC 002);
Machine is not enabled;
Any valid ground control input becomes active;
Controls Initialized.
00 39 SKYGUARD ACTIVE – FUNCTIONS CUTOUT Machine is in Platform Mode and SkyGuard
Enabled
Trigger conditions are no longer true
00 47 DRIVING IN CREEP – STEEP DESCENT UGM detects that the machine is descending a
grade steeper than the MAX Grade setpoint
(greater than or equal to):
MAX Grade Setpoint = 19 degrees for a period of
greater than 1 second.
[MACHINE SETUP = E400 or 450].
The UGM detects that the grade in direction of
travel is more than 3 degrees less than the
machine’s trip point.
