Owner's Manual for Power Zone Pro Sync
Description
This fault indicates the ECU has
stopped communicating with the
Main Controller over the J1939
CAN bus. This can result from an
open/shorted CAN bus, loss of
ECU switched power, E-Stop
pushed, ECU fuse, etc.
This fault indicates the ECU is
requesting the system to wait
before cranking. This is normally
due to a preheat function such as
glow plugs.
This warning indicates the ECU is
derating the engine performance
to protect it from damage. This is
normally due to temperatures or
pressures being out of the
optimal ranges, but each ECU
has its own conditions that it
uses.
This warning indicates the ECU
has detected an adverse
condition and has likely logged an
Suspect Parameter Code (SPN)
code. Each ECU has its own
conditions that it uses.
This alarm indicates the ECU has
detected a fault condition that
adversely affects emissions.
This shutdown alarm indicates
the ECU has detected a fault
condition that requires the engine
to be stopped to protect it from
damage.
This shutdown alarm indicates
the ECU has detected a fault
condition that requires the engine
to shut down. It then shuts down
the engine.
