LOAD SENSOR READING UNDER
WEIGHT 0015 LSS has been calibrated and the UGM has determined that the load
sensing system reading is less than -50lbs for 2 seconds. If the load
sensing system determines that the reading is greater than -50lbs for 5
seconds this fault will no longer be annunciated.
No control system interlocks present when DTC is active.
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.
