440 4 4 <<< BATTERY SUPPLY >>>
441 4 4 BATTERY VOLTAGE TOO LOW - SYSTEM
SHUTDOWN Battery voltage is < 9V.
442 4 4 BATTERY VOLTAGE TOO HIGH - SYSTEM
SHUTDOWN Battery voltage is > 16V.
443 4 4 LSS BATTERY VOLTAGE TOO HIGH The load sensor has determined that its
supply voltage is too high (> 16V).
The machine will assume the platform is
overloaded.
Check for issue with sensor supply voltage.
444 4 4 LSS BATTERY VOLTAGE TOO LOW The load sensor has determined that its
supply voltage is too low (> 8V).
The machine will assume the platform is
overloaded.
Check for issue with sensor supply voltage.
445 4 4 BATTERY VOLTAGE LOW Battery voltage is < 11V for more then 5
seconds.
4479 4 4 LSS BATTERY VOLTAGE - INITIALIZATION
ERROR The shear beam is reporting a Sensor Sup-
ply Voltage Initialization Error
The machine will assume the platform is
overloaded.
This fault, once annunciated is latched
within a given key cycle.
Possible sensor hardware issue.
4480 4 4 LSS BATTERY VOLTAGE - NOT CALIBRATED The shear beam is reporting a Sensor Sup-
ply Voltage calibration error.
The machine will assume the platform is
overloaded.
This fault, once annunciated is latched
within a given key cycle.
Possible sensor hardware issue.
660 6 6 <<< COMMUNICATION >>>
662 6 6 CANBUS FAILURE - PLATFORM MODULE Platform Module CAN communication lost.
663 6 6 CANBUS FAILURE - LOAD SENSING SYSTEM
MODULE The control system has lost communication
with the load sensing system load pin.
The machine will assume the platform is
overloaded.
Check wiring to load sensor.
666 6 6 CANBUS FAILURE - ENGINE CONTROLLER Engine Control Module CAN
communication lost. - ECM equipped engine only.
6610 6 6 CANBUS FAILURE - BLAM BLAM CAN communication lost. - BLAM equipped vehicles only.
6611 6 6 CANBUS FAILURE - CHASSIS MODULE Engine Control Module CAN
communication lost. - ECM equipped engine only.
6612 6 6 CANBUS FAILURE - CYLINDER LOAD PIN Cylinder Load Pin CAN communication lost. - Cylinder Load Pin equipped engine only.
6613 6 6 CANBUS FAILURE - EXCESSIVE CANBUS
ERRORS There has been > 500 Bus Off errors or
>500 Bus Passive Errors.
