X TABLE OF CONTENTS
TABLE OF CONTENTS
The fuel pump, mounted inside the fuel tank on the vehicle, is
a submersible pump used to provide fuel to the fuel injectors.
The fuel pump is protected by an in-line 15 amp replaceable
fuse.
•
When the ignition switch is in the IGNITION position and
the engine stop switch is in the RUN position, the ECM
grounds the system relay supplying voltage to the fuel
pump.
•
The fuel pump continues running during cranking and
normal running operation, as long as the ECM is receiving
input from the CKP sensor. If no CKP pulses are received,
the ECM shuts off the system relay within 2 seconds after
the ignition is turned on, the engine has stalled or immedi-
ately after the engine is shut off.
•
The fuel pump contains a pressure regulator which main-
tains consistent fuel pressure to each of the fuel injectors.
Excess fuel flow is bypassed into the fuel tank by the
pressure regulator.
There are two fuel injectors mounted to the intake manifold.
The ECM controls the injectors by actuating the injector
solenoid enabling fuel to be metered through the injector and
atomized into the intake manifold.
•
The injectors are timed to the combustion cycle and are
triggered sequentially. When the ECM determines that
fuel is required, the ECM supplies a short duration ground
to the fuel injector, which opens and releases fuel into the
air intake manifold.
•
The ECM grounds the system relay, which supplies voltage
to the fuel injectors. Each injector is protected and
grounded by the ECM, through a common point ground
within the ECM.
The purge solenoid (working with the charcoal canister) allows
the vapors to escape back into the throttle body. The purge
solenoid is timed to the throttle position but is disabled at
startup, low engine temperature, low engine speed or low
vehicle speed. The power for the purge solenoid comes from
the system relay. The ECM provides the path to ground to
trigger the purge solenoid.
Heat Management System
To improve rider comfort on all stock Touring model motor-
cycles, an optional heat management system may be enabled.
After being enabled, the heat management system improves
rider comfort by turning off the rear cylinder fuel injector when
all of the following conditions exist:
•
High engine temperature
•
Engine at idle speed
•
Low or no vehicle speed
•
Clutch lever pulled in or transmission in neutral
As the engine maintains idle speed, the rear cylinder functions
as an "air pump," helping to cool the engine. This continues
until one of the above listed conditions is no longer met, then
the rear cylinder fires normally again.
NOTE
When the engine is in heat management mode, a noticeable
difference in idle may be accompanied by a unique exhaust
odor. While these conditions are normal, a rider or technician
unaware of the heat management system may incorrectly
assume an idle problem is present.
Enable/Disable EITMS
1.
Turn the ignition ON with the motorcycle at idle and not
moving (the motorcycle may be running or not running).
2.
Push the throttle to roll-off position and hold.
3.
After approximately 3 seconds, the cruise indicator will
flash either red (disabled) or green (enabled).
4.
Repeat step two to change.

ELECTRONIC CONTROL MODULE
GENERAL
.The ECM receives and processes signals from
the sensors and applies output signals to the drivers to start,
idle and run the engine. This section describes the configuration
of the ECM for this vehicle.

Figure 6-2. Electrical Connectors Under Seat
ECM
The ECM is mounted under the seat. It computes the spark
advance for proper ignition timing and fuel control based on
sensor inputs (from ET, CKP, TMAP, TGS, HO2S and VSS
sensors) and controls the low-voltage circuits for the ignition
coils and injectors.
The ECM contains all of the components used in the ignition
system. The dwell time for the ignition coil is also calculated
in the microprocessor and is dependent upon battery voltage.
The programmed dwell is an added feature to give adequate
spark at all speeds. (The ECM has added protection against
transient voltages, continuous reverse voltage protection and
damage due to jump starts.) The ECM is fully enclosed to
protect it from vibration, dust, water or oil. This unit is a non-
repairable item. If it fails, it must be replaced. When the ECM
is replaced, see the service manual.
32-2 Flywheel
The left flywheel has 32 teeth evenly spaced around its circum-
ference with two consecutive teeth missing (sync gap). In this
configuration, the ECM determines engine position, engine
phase and engine speed from the CKP sensor input. Phase
(TDC compression) is determined by the ECM during startup
