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.
Examples 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. Examples 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. Examples of these
devices are GCON up and down switches and
PCON drive joystick.
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. Examples
of these devices are limit switches, height sensors
and pressure transducers.
Type "CXXX" – Indicate a malfunction associated
