Section 03 ELECTRONIC MANAGEMENT SYSTEMS
Subsection 01 (ENGINE MANAGEMENT SYSTEM)
GENERAL
SYSTEM DESCRIPTION
There are 7 main systems in interaction with the
engine management system:
1. Electronic fuel injection
2. D.E.S.S. syst
em
3. Ignition system
4. Starting system
5. O.T.A.S. (Of
f-Throttle Assisted Steering)
6. Lubrication system (T.O.P.S. (Tip-Over Protec-
tion System))
7. iControl system
Engine Cont
rol Module (ECM)

027-005
ECM
The ECM controls the electrical system and the
engine management functions, by processing the
information given by various sensors.
It also exchange information with the other elec-
tronic systems through the CAN bus (information
center and iControl System.
The ECM is mounted on the intake manifold.

intake manifold
Engine RPM Limiter
The ECM will limit the maximum engine speed.
The ECM monitors engine RPM through the CPS
and it changes the fuel injection and ignition as
necessary.
Engine Speed Control
The ECM controls the engine idle RPM. It in-
creases and reduces the engine speed by using
the throttle actuator. The throttle actuator allows
many functions for the iControl system.
Drowned Mode
If engine is fuel-flooded or water-flooded and does
not start, this special mode can be activated to
prevent fuel injection and ignition while cranking
in order to ventilate the engine to dry the cylinder
walls.
NOTE: This mode can also be used if engine is
water-flooded.
Proceed as follows to activate it.
With safety lanyard on its post while engine is
stopped, press and HOLD throttle lever.
Press the START/STOP button. The mode is now
on.
Releasing throttle lever will bring back to its nor-
mal mode.
If engine does not start, it may be necessary to
remove spark plugs and crank engine with rags
over spark plug holes. Refer to
IGNITION SYS-
TEM
subsection.
Monitoring System
The ECM monitors the electronic components of
the fuel injection system, the iControl system, the
information center (gauge) and also some compo-
nents of the electrical system.
For more information, refer to
MONITORING SYS-
TEM AND FAULT CODES.
Limp Home Mode
The ECM may automatically use default parame-
ters for the engine management to ensure the ad-
equate operation of the watercraft if a component
of the fuel injection system or iBR is not operat-
ing properly. For more information, refer to
MON-
ITORING SYSTEM AND FAULT CODES
.
Diagnostic Mode
The ECM features a self-diagnostic mode when
pressing the START button. However, some com-
ponents need the engine to be running so that
they can be monitored. Some problems will turn
on a warning lamp or beeper, or will set the engine
