Scan Tool Data Definitions
Inj Pulse Width #1 (Fuel Injection Pulse Width No.1,
msec.)
This parameter indicates time of the injector drive (valve
opening) pulse which is output from ECM.
Inj Pulse Width #2 (Fuel Injection Pulse Width No.2,
msec.)
This parameter indicates time of the injector drive (valve
opening) pulse which is output from ECM.
Inj Pulse Width #3 (Fuel Injection Pulse Width No.3,
msec.)
This parameter indicates time of the injector drive (valve
opening) pulse which is output from ECM.
Gas Inj Pulse Width #1 (Gas Injection Pulse Width
No.1, msec.)
This parameter indicates time of LPG fuel injector drive
(valve opening) pulse which is output from LPG control
module.
Gas Inj Pulse Width #2 (Gas Injection Pulse Width
No.2, msec.)
This parameter indicates time of LPG fuel injector drive
(valve opening) pulse which is output from LPG control
module.
Gas Inj Pulse Width #3 (Gas Injection Pulse Width
No.3, msec.)
This parameter indicates time of LPG fuel injector drive
(valve opening) pulse which is output from LPG control
module.
Calculated Load (Calculated Load Value,%)
This parameter indicates the percentage of engine load
calculated based on input signal to ECM from various
engine sensors.
Engine Speed (rpm)
This parameter indicates the calculated engine speed
based on reference pulses from the camshaft position
sensor.
Vehicle Speed (km/h, MPH)
This parameter indicates the calculated vehicle speed
based on vehicle speed sensor signal.
MAP (Manifold Absolute Pressure, kPa, inHg, inH2O,
mmHg, psi)
This parameter indicates the calculated manifold
pressure based on MAP sensor signal.
ECT (Engine Coolant Temperature, °C, °F)
This parameter indicates the calculated engine coolant
temperature based on ECT sensor signal.
Intake Air Temperature (°C, °F)
This parameter indicates the calculated intake air
temperature based on IAT sensor signal.
Throttle Position (Absolute Throttle Position,%)
This parameter indicates the calculated opening
percentage of throttle valve based on signal voltage of
throttle position sensor.
0 – 5%: Throttle valve position is fully closed.
90 – 100%: Throttle valve position is fully opened.
CNG/LPG Lack Counter (Times)
This parameter indicates frequency of fuel shortage
calculated by LPG control module.
CNG/LPG Filling Counter (Times)
This parameter indicates frequency of refueling
calculated by LPG control module.
Fuel Select Mode (Auto / Petrol / Gas)
This parameter indicates the state of fuel select mode.
Auto: AUTO MODE is selected.
Petrol: Petrol MODE is selected.
Gas: Forced LPG MODE is selected.
