5.3-3 LED Error Codes - Code Breakdown Chart (Continued)
Vehicle Tilted 11
Vehicle Overloaded 12
Too High - Drive Prevented 14
Too High - Lift Up Prevented 15
These are not true faults but an indication that vehicle movement is prevented. Remove excessive load from the
platform. Lower the platform if close to maximum height. Move the vehicle to level ground.
Invalid Height - Check Sensor 65
Check the voltage out of the height transducer, into P4-3. It should be between .4V and 4.6V and should vary as
the platform position varies.
Testing HWFS 78
Start Up! 77
These are not true faults unless they do not clear – the start-up tests should only occur for a short time.
Overload Functions Disabled! 66
Factory Override 67
These are not true faults – the GP102 has been configured to suppress overload functionality.
Idle Timeout Active! Always Off
Fault: Bad Tilt Sensor 71
Fault: Bad HWFS 72
Fault: Bad Slave Analogs 73
Fault: Bad Strain Monitors 74
Fault: Bad Slave Micro 75
Fault HWFS Stalled! 76
Action a function to clear the idle timeout if it occurred. Ensure the GP102 is correctly mounted – incorrect
mounting can cause the “bad tilt sensor” diagnostic to occur. Otherwise there may be an internal problem with the
GP102.
