CHASSIS TILT SENSOR NOT
CALIBRATED 813 The tilt sensor has not been calibrated The Ground Module reports a
faulted chassis tilt angle of 90
degrees Calibrate the Tilt sensor to clear
the fault
CHASSIS TILT SENSOR OUT OF
RANGE 814 Fault CHASSIS TILT SENSOR NOT CALIBRATED (813) is not present and
Tilt sensor measurement greater than 19º for 4 seconds. Note: Not to
be reported during Tilt Sensor calibration. No additional action required
beyond Tilted requirements
specified above. Ground Mod-
ule reports 90
° angle.
Tilt sensor reads less than 19º.
CHASSIS TILT SENSOR DIS-
AGREEMENT 815 The Ground Module detects one of the following conditions:
If a Drive, Steer, or Boom function is active or if the engine is cranking
or if the primary raw Tilt Sensor readings greater than ±10 º then: if
the two ground board tilt sensors disagree by more than or equal to 3
degrees for either the X axis or the Y axis for longer than 5 seconds
then the fault will be logged.
If no Drive, Steer, or Boom functions are active and the engine is not
cranking or the primary raw Tilt Sensor readings are less than ±10 º
then: if the two ground board tilt sensors disagree by more than or
equal to 1 degree for either the X axis or the Y axis for longer than 3
seconds then the fault will be logged.
Note: This fault is not reported if DTC 814 is active.
The Ground Module reports a
faulted chassis tilt angle of 90
degrees Cycle power to clear the fault.
LSS CELL #1 ERROR 821 MACHINE SETUP  LOAD SYSTEM is not set = NO
The Ground Module detects that LSS is reporting error with Cell #1
Ground Module to assume Plat-
form Load State = Overloaded CAN messages are received
from the LSS module.
LSS CELL #2 ERROR 822 MACHINE SETUP  LOAD SYSTEM is not set = NO
The Ground Module detects that LSS is reporting error with Cell #2
Ground Module to assume Plat-
form Load State = Overloaded CAN messages are received
from the LSS module.
LSS CELL #3 ERROR 823 MACHINE SETUP  LOAD SYSTEM is not set = NO
The Ground Module detects that LSS is reporting error with Cell #3
Ground Module to assume Plat-
form Load State = Overloaded CAN messages are received
from the LSS module.
LSS CELL #4 ERROR 824 MACHINE SETUP  LOAD SYSTEM is not set = NO
The Ground Module detects that LSS is reporting error with Cell #4.
Ground Module to assume Plat-
form Load State = Overloaded CAN messages are received
from the LSS module.
LSS HAS NOT BEEN CALI-
BRATED 825 MACHINE SETUP  LOAD SYSTEM is not set = NO
The load sensor has not been calibrated
Ground Module to assume Plat-
form Load State = Overloaded CAN messages are received
from the LSS module.
