(
Neutral switch status
The 'neutral' or 'in gear' status of the gear change.
Off idle fuel trim
The percentage above or below the nominal fuel
requirement for the volume of air entering at engine
speeds other than idle. This function is not currently used
in the Triumph system.
Open circuit
A break in an electrical circuit - current cannot flow.
Over temp
High temperature within the Engine Control
Module (ECM) caused by an internal or external
failure.
Primary Throttle Position Sensor
Sensor for the primary (lower) throttle position.
Primary Throttle Stepper Motor
Stepper motor used to vary throttle opening at idle and
when the engine is cold.
Purge valve duty cycle
The time the purge valve is open in an open I close cycle,
expressed as a percentage of the cycle time.
Road Speed Sensor
Gearbox mounted sensor which delivers information to
the ECM that is converted to the road speed value that is
displayed on the speedometer.
Second Throttle Position Sensor
Sensor for the second (upper) throttle position.
Second Throttle Stepper Motor
Stepper motor used to vary all second throttle positions,
on or off idle.
Sensor reference voltage
Supply voltage to the system sensors (nominaily 5 volts).
Short circuit
A 'short cut' in an electrical circuit - current by-passes the
intended circuit (usually to earth).
Short term fuel trim
A correction applied to the fuel mixture during closed
loop catalyst operation. This, in turn, has an effect on the
long term fuel trim in that if an engine constantly requires
mixture correction, the long term fuel trim will adapt to
this requirement thus reducing the need for constant
short term adjustment.
Fuel System/Engine Management
Sidestand status
The 'up' or 'down' position of the side stand.
Target dwell time
The actual time from coil 'on' to coil 'off.
Throttle position
The position of the throttle butterfly given as a percentage
of the movement range. When the data is displayed on
the tooi, fuily open need not be 1000/0 nor fully closed
00/0.
Throttle voltage
Voltage at the throttle potentiometer.
Vbatt
Battery voltage.
