Table 6-17. Diagnostic Trouble Codes
DTC Text
The PM detects that the Lift or Swing joystick sig-
nal voltage > 8.1V and reports the fault to the
UGM.
The PM detects that the Lift or Swing center tap
voltage is not between 3.31 volts and 3.75 volts
and reports the fault to the UGM
The machine is in Platform Mode and the Lift and/
or Swing controls are not in the neutral position
immediately following Start Up -OR- The
machine is in Platform Mode and a proper
machine enable signal is received or DTC 2212,
2213 or 2223 is active while the Lift/Swing joy-
stick is not in the neutral position.
Machine is in Platform Mode AND Footswitch has
been engaged since Start Up
The machine is in Platform Mode and a proper
machine enable signal is received or DTC 2212,
2213 or 2221 is active while any of the following
boom control inputs are engaged: AWDA Enable,
Tower Lift, Telescope, Platform Level, Platform
Rotate, Jib Lift (if MACHINE SETUP -> JIB = YES)
and Jib Rotate (if MACHINE SETUP -> JIB PLUS =
YES)
The machine is in Platform mode and the Jib Swing
Left input = High at Startup

Fault Description
The PM detects that the lift/swing center tap
voltage is between 3.31 and 3.75 volts and no
longer reports the fault to the UGM
The PM detects that the lift/swing center tap
voltage is between 3.31 and 3.75 volts and no
longer reports the fault to the UGM
If triggered by the Lift/Swing controls not being
in the neutral position immediately following
Start Up, then when Lift/Swing controls are
returned to neutral and the machine is not in
the Enabled state.
If triggered by proper machine enable signal
being received while the Lift/Swing controls are
not in the neutral position, then when the Lift/
Swing controls are returned to neutral or the
footswitch is released
Footswitch is disengaged
None of the boom controls that trigger this fault
are engaged or the Footswitch is disengaged.
Jib Swing Left input = LOW while the machine is
not Enabled
Jib Swing Right input = LOW while the machine
is not Enabled
Platform Rotate Left input = LOW while the
machine is not Enabled
Platform Rotate Right input = LOW while the
machine is not Enabled
Jib Lift Up input = LOW while the machine is not
Enabled
Jib Lift Down input = LOW while the machine is
not Enabled
Telescope In input = LOW while the machine is
not Enabled
Telescope Out input = LOW while the machine is
not Enabled
Telescope Out input = LOW while the machine is
not Enabled
Tower Lift Down input = LOW while the machine
is not Enabled
Platform Level Up input = LOW while the
machine is not Enabled
Platform Level Down input = LOW while the
machine is not Enabled
