Subsection 01 (ENGINE MANAGEMENT SYSTEM (EMS))
Engine RPM Limiter
The ECM limits the maximum engine speed with
the shifter selected to any position. It uses the
CPS and the GBPS for this function.
An override switch, on the handlebar, allows the
engine to be run at a higher speed than the RPM
limiter when more power is needed in reverse op-
eration. Refer to
LIGHTS, GAUGE AND ACCES-
SORIES
.
Vehicle Speed Limiter
The ECM will limit the maximum vehicle speed.
For this purpose, the ECM uses the VSS and the
GBPS.
Drowned Mode (Flooded Engine)
If the engine is fuel-flooded and does not start,
this special mode can be activated to prevent fuel
injection and ignition while cranking. Proceed as
follows to activate it.
With the ignition key set to ON and the engine
stopped, press and HOLD the throttle lever to
WOT position (wide open throttle).
Press the start button. Drowned mode is now on.
Releasing the throttle lever will bring back the nor-
mal mode.
Monitoring System
The ECM monitors the electronic components
of the fuel injection system and also parts of the
electrical system.
For more information, refer to
DIAGNOSTIC AND
FAULT CODES
.
Limp Home Mode
The ECM may automatically set default parame-
ters to the engine management to ensure the ad-
equate operation of the engine if a component of
the fuel injection system is not operating prop-
erly. The engine will operate with reduced per-
formance to protect the engine. In more severe
cases, the engine RPM will be limited, also to pro-
tect the engine.
These performance-reduced modes allow the
rider to go back home which would not be oth-
erwise possible. Refer to the
DIAGNOSTIC AND
FAULT CODES
subsection.
Diagnostic Mode
The ECM features a self-diagnostic mode when
the ignition key is turned on. However, some
components need the engine to be running so
that they can be monitored. Some problems will
turn on a warning lamp or will set the engine in
limp home mode. Refer to
DIAGNOSTIC AND
FAULT CODES
section for more information.
