Operational Indicator Codes

(OIC)
These codes are generated by the electrical
system to indicate machine operating status
such as Off-level, Overload Cutout, Chassis
Mode Operation and Pothole Guard Stuck,
during normal operation.
These codes are not indicators of a device
malfunction in the electrical system.
Code Condition
LL Off-Level
OL Platform Overloaded (CE and Australia)
CH Chassis Mode Operation
PHS Pothole Guard Stuck
OAC Obstruction Above Chassis (QSR only)
ND No Drive (option)
5 - 6
Diagnostic Trouble Codes (DTC)
These codes are generated by the system to
indicate that a device or circuit malfunction has
been detected in the electrical system.
The types of Diagnostic Trouble Codes that may
occur are explained below.
Type "HXXX" - Indicate a malfunction
associated with devices that control hydraulic
functions in the electrical system. The "HXXX"
faults are divided into short circuit battery
negative, short circuit to battery positive, open
circuit and generic shorts. Example of these
devices are solenoid controlled hydraulic valves
and motor controller.
Type "PXXX" - Indicate a malfunction associated
with power type devices in the electrical system.
The "PXXX" faults are divided into short circuit
to battery negative, short circuit to battery
positive, open circuit and generic shorts.
Example of these devices are horns, sensor
power and alarms.
Type "UXXX" - Indicate a malfunction
associated with user interface devices in the
electrical system. The "UXXX" faults are divided
into short circuit to battery negative, short circuit
to battery positive, open circuit and generic
shorts. Example of these devices are GCON up
and down switches and PCON drive joystick
faults.
Type "FXXX" - Indicate a malfunction associated
with machine feedback devices in the electrical
system. The "FXXX" faults are divided into short
circuit to battery negative, short circuit to battery
positive, open circuit and generic shorts.
Example of these devices are limit switches,
height sensors and pressure transducers.
Type "CXXX" - Indicate a malfunction
associated with controls devices in the electrical
system. Example of these devices are platform
controls and ground controls ECM.
