Service and Repair Manual November 2016Fault Codes98 GS-2669 DC • GS-3369 DC • GS-4069 DC Part No. 1272220GTOperati on Indi cator C odes (OIC)Operation Indicator Codes (OIC)These codes are generated by the electricalsystem to indicate machine operating status suchas Off-level, Overload Cutout, Chassis ModeOperation during normal operation. These codesare not indicators of a device malfunction in theelectrical system.Code ConditionLL Off-LevelOL Platform Overload (CE and Australia)CH Chassis Mode Operationnd No Drive (option)Ld Lifting Disabled (option)Diagnostic Tr ouble Codes (DTC)Diagnostic Trouble Codes (DTC)These codes are generated by the system toindicate that a device or circuit malfunction hasbeen detected in the electrical system.The types of Diagnostic Trouble Codes that mayoccur are explained below.Type "HXXX" – Indicate a malfunction associatedwith devices that control hydraulic functions in theelectrical system. The "HXXX" faults are dividedinto short circuit battery negative, short circuit tobattery positive, open circuit and generic shorts.Examples of these devices are solenoid controlledhydraulic valves and motor controller.Type "PXXX" – Indicate a malfunction associatedwith power type devices in the electrical system.The "PXXX" faults are divided into short circuit tobattery negative, short circuit to battery positive,open circuit and generic shorts. Examples of thesedevices are horns, sensor power and alarms.Type "UXXX" – Indicate a malfunction associatedwith user interface devices in the electrical system.The "UXXX" faults are divided into short circuit tobattery negative, short circuit to battery positive,open circuit and generic shorts. Examples of thesedevices are GCON up and down switches andPCON drive joystick.Type "FXXX" – Indicate a malfunction associatedwith machine feedback devices in the electricalsystem. The "FXXX" faults are divided into shortcircuit to battery negative, short circuit to batterypositive, open circuit and generic shorts. Examplesof these devices are limit switches, height sensorsand pressure transducers.Type "CXXX" – Indicate a malfunction associatedwith controls devices in the electrical system.Examples of these devices are platform controlsand ground controls ECM.
