After Market Device - An after market device is a device or an accessory that is installed by the customer after the vehicle is delivered.Air-To-Air Aftercooler (ATAAC) - An air-to-air aftercooler is a device that is used on turbocharged engines in order to cool inlet air that has undergone compression. The inlet air is cooled after the inlet air passes through the turbocharger. The inlet air is passed through an aftercooler (heat exchanger) that uses ambient air for cooling. The inlet air that has been cooled advances to the inlet manifold. American Wire Gauge (AWG) - AWG is a measure of the diameter of electrical wire. AWG is also a measure of the current carrying capacity of electrical wire. When the AWG number is smaller, the diameter of the wire is larger. When the AWG number is larger, the diameter of the wire is smaller.Atmospheric Pressure Sensor - The atmospheric pressure sensor measures barometric pressure. The sensor sends a signal to the electronic control module (ECM). The signal is used in engine control and in engine operation.Before Top Center (BTC) - BTC is the 180 degrees of crankshaft rotation before the piston reaches the top center position in the normal direction of rotation.Boost Pressure Sensor - The boost pressure sensor measures inlet manifold air pressure. The boost pressure sensor sends a signal to the Electronic Control Module (ECM).Bypass Circuit - A bypass circuit is a circuit that is used as a substitute circuit for an existing circuit. A bypass circuit is typically used as a test circuit.Caterpillar Electronic Technician (ET) - The Caterpillar Electronic Technician (ET) is a software program that runs on a personal computer (PC). ET is used to service Caterpillar products. This program has replaced the ECAP service tool.Calibration - Calibration is an electronic adjustment of a sensor signal.Coolant Temperature Sensor - The coolant temperature sensor measures the engine coolant temperature. The sensor sends a signal to the electronic control module (ECM). The engine's coolant temperature is used in Cold Mode operation. Coolant temperature is also used in order to optimize engine performance.Cruise Control Range - The cruise control range establishes the vehicle speed range for the operation of cruise control. The range is usually limited to the speed range that is anticipated on the open road.Code - See the Diagnostic Code.Customer Specified Parameters - A customer specified parameter is a parameter that can be changed. A customer specified parameter's value is set by the customer. These parameters are protected by customer passwords.CAT Data Link (CDL) - The CAT Data Link (CDL) is a serial communication port that is used for communication with other microprocessor based devices.Desired RPM - The desired rpm is input to the electronic governor within the ECM. The electronic governor uses the signal from the Accelerator Pedal Position Sensor, the Engine Speed Sensor, the Cruise Control, and the Customer Parameters in order to determine desired rpm.Diagnostic Code - A diagnostic code is sometimes called a fault code. A diagnostic code is
