Fault Shutdowns
Code Description
Check A check engine
engine fault occurs when
(fault) [ the ECM sends a
signal for the
generator set
controller to shut
down because the
engine has stalled
ECM voltage No or low voltage
(fault) ] to the ECM
[ Note: Available on software version 1.3.0 or higher. On software version 1.2.0 and below, this condition was displayed as Out of fuel.

Warnings
Code Description
High battery High battery
voltage warning.
Fault condition
clears when the
battery voltage
returns to a
voltage within the
limits.
Low battery Low battery
voltage warning.
Fault condition
clears when the
battery voltage
returns to a
voltage within the
limits.
Weak Low cranking

Hi CO: High CO from
engine ECM. Fault code
is displayed if the
presence of CO is
detected because
of the
time-weighted
average presence
of CO. Activates
the CO cabin
alarms.
