The ECM is responsible of the following electrical
functions:
Digitally Encoded Security System (DESS)
This antistart system allows starting the vehicle
only with safety lanyard(s) that has been pro-
grammed to operate a specific watercraft. Refer
to DESS.
Safety Lanyard Reminder
If engine is not started within 5 seconds after
installing the safety lanyard on its post, 4 short
beeps every 3 second interval will sound for ap-
proximately 2 hours to remind you to start the en-
gine or to remove safety lanyard. Afterwards, the
beeps will stop. The same will occur when safety
lanyard is left on its post 5 seconds after engine is
stopped.
Always ensure safety lanyard is not left on its post
after engine is stopped.
IMPORTANT: Leaving the safety lanyard on its
post when engine is not running will slowly dis-
charge the battery.
Engine Starting
If the ECM recognizes a valid safety lanyard, it
allows engine to start when the start/stop button
is pressed.
If start/stop button is held after engine has started,
the ECM automatically stops the starter when the
engine speed reaches 1000 RPM.
If start button is activated while the throttle lever
is depressed more than 70%, the engine will not
beallowedtostart.
Engine Stopping
There are 2 ways to stop the engine.
Press start/stop button or remove the safety lan-
yard cap from its post.
Maximum Engine Speed
The ECM limits the maximum allowable engine
speed. The RPM rev limiter is set at 7200 ±
50 RPM.
Drowned Mode (Flooded Engine)
This mode allows to crank engine to expel accu-
mulated fuel or water out of cylinders. No fuel
is injected and no ignition occurs while cranking
in this mode. Proceed as follows to activate the
drowned mode:
Remove spark plug cables and connect them on
the grounding device.
