9 FUEL SYSTEM/ENGINE MANAGEMENT
Closed throttle position
Throttle position at idle (i.e. against end stop), measured
as a voltage and expressed as percentage.
0% = 0 volts
1 00%
= 5 volts
Coolant temperature
The coolant temperature in the thermostat housing.
Coolant temperature sensor
Measurement in volts at the Electronic Control Module
(ECM) of the coolant temperature in the thermostat
housing as signalled by the coolant temperature
~ensor.
Cooling fan status
The 'on' or 'off' condition of the cooling fan.
Corrected Throttle Position
The electronic value of the throttle position corrected
according to the closed value of the throttle
potentiometer. The reading for corrected throttle
position will be different to the actual throttle position.
DTC
Diagnostic Trouble Code.
ECM
Electronic Control Module.
Engine speed
The crankshaft revolutions per minute of the engine.
Freeze frame
A data set captured at the time a Diagnostic Trouble
Code (DTC) is set.
IACV
Idle Air Control valve.
Idle air control valve stepper position
The position of the idle air control valve stepper motor;
o
=. fully closed.
180 = fully open
9.8
Idle fuel trim
The· percentage above or below the nominal fuel
requirement for the volume of air entering at idle.
Idle fuelling
Adjustment of fuel at idle to suit the actual air inducted.

The target idle speed as determined by the Electronic
Control Module (ECM). (It should be the same as the
actual idle speed ifthe motorcycle is operating correctly.)
Ignition advance
The timing of ignition at the spark plug relative to top
dead centre.
Ignition switch position
The 'on' or 'off' position of either or both the ignition
switch and the engine stop switch.
Ignition timing
Same as 'Ignition advance'.
Injector pulse time
The time during which an injector remains open.
Lambda sensor
See oxygen sensor.
Long term fuel trim
Fueling after adapting to the engine's long term fuelling
requirements (closed loop only). See also short term fuel
trim.
MIL
Malfunction Indicator Lamp.
Illuminates when Diagnostic Trouble Codes (DTC's) are
set.
Neutral switch status
The 'neutral' or 'in gear' status of the gearchange.
