Fault Description
Battery voltage is < 9V.
Battery voltage is > 16V.
The load sensor has determined that its
supply voltage is too high (> 16V).
The machine will assume the platform is
overloaded.
The load sensor has determined that its
supply voltage is too low (> 8V).
The machine will assume the platform is
overloaded.
Battery voltage is < 11V for more then 5
seconds.
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.
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.
Platform Module CAN communication lost.
The control system has lost communication
with the load sensing system load pin.
The machine will assume the platform is
overloaded.
Engine Control Module CAN
communication lost.
BLAM CAN communication lost.
Engine Control Module CAN
communication lost.
Cylinder Load Pin CAN communication lost. - Cylinder Load Pin equipped engine only.
There has been > 500 Bus Off errors or
>500 Bus Passive Errors.
