Fault Description
Machine Setup/ Telematics=YES, No
device heartbeat for 30 sec

X
X
The Chassis Tilt Sensor has not been cali-
brated.
Tilt sensor out of range
X
Disagreement between internal (UGM) and
external chassis tilt sensors
LSS has been calibrated and the UGM has
determined that the load sensing system
reading is underweight while a period of
time while operating drive or boom lift up
at speeds greater than creep OR the UGM
has determined that the load sensing sys-
tem reading is less than -1.5 x Gross Plat-
form Weight.
The machine will assume the platform is
overloaded.
This fault, once annunciated is latched
within a given key cycle.
SECTION 6 - JLG CONTROL SYSTEM
Check
-Telematics only
-Telematics only
Check sensor hardware and wiring
Check external/internal sensor hardware and installa-
tion on machine
Ensure platform is not resting on the ground or is not
leveled at an extreme negative angle.
Re-calibrate the load sensing system if the above
items are not a factor.
