presence from
sensor.
Shutdown occurs
because of the
presence of CO.
Pulsed signal 20 Hz 0sec 10 sec N/A Immediate service required.
Contact an authorized
distributor/dealer for service.
Ensure windows are open for proper
ventilation.
Operate the blower to expel
dangerous fumes.
Move the vessel away from other
vessels (as another vessel may be the
source for the presence of the CO).
Check the generator exhaust system
(see Section 3.6).
Hi CO:
engine
(fault)
Carbon monoxide
fault from ECM.
Shutdown occurs
because of the
presence of CO or
deteriorating
emission-control
components (such
as the catalyst).
ECM data Control limit 0sec 15 sec N/A Immediate service required.
Contact an authorized
distributor/dealer for service.
Ensure windows are open for proper
ventilation.
Operate the blower to expel

vessels (as another vessel may be the
source for the presence of the CO).
Check the generator exhaust system
(see Section 3.6).
No CO
sensor
(fault)

sensor missing
shutdown occurs
if communication
is lost between
the CO sensor
and the ADC.
Pulsed signal No signal 0sec 10 sec N/A Check the connections to the CO
sensor. If connections are okay,
replace the CO sensor.
Contact an authorized
distributor/dealer for service.
