American Trucking Association (ATA) Datalink
A serial datalink specified by the American Trucking
Association and the SAE.
Analog Signal
A continuously variable voltage.
Barometric Absolute Pressure (BAP) Sensor
A variable capacitance sensor which, when supplied
with a 5 volt reference signal from the ECM, produces
a linear analog voltage signal indicating atmospheric pressure.
Boost Pressure
The pressure of the charge air leaving the turbocharger.
Camshaft Position (CMP) Sensor
A magnetic pickup sensor that indicates engine speed and
camshaft position.
CAN 1
A data link between the vehicle modules and ECM.
CAN 2
The private link between the ECM and IDM.

and associated parts.
Crankshaft Position (CKP) Sensor
A magnetic pickup sensor that determines crankshaft
position and speed.
Duty Cycle
A control signal that has a controlled on/off time measurement
from 0 to 100%. Normally used to control solenoids.
Electronic Control Module (ECM)
An electronic processor that monitors and controls the engine.
EGR Cooler
