between microprocessor based devices. The devices must be compatible with the American Trucking Association and SAE Standards (J1587 and J1708) such as trip recorders, electronic dashboards, and maintenance systems. The ATA Data Link is the communication medium that is used for the programming and the troubleshooting with Caterpillar electronic service tools.Aftermarket Device - An aftermarket device is a device or an accessory that is installed by the customer after the vehicle is delivered.Air-To-Air Aftercooler - 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. Alternating Current (AC) - The direction of the current flow changes. The current flow alternates constantly.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 Engine 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 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.Calibration - Calibration is an electronic adjustment of a sensor signal.CAT Data Link - The data link is an electrical connection that is used to communicate with other devices that utilize microprocessors. The microprocessor based devices are compatible with the proposed American Trucking Association and the SAE standard. These devices include trip recorders, electronic dashboards, and maintenance systems. The data link is also the communication medium that is used for programming with the electronic service tool. The data link is also used for troubleshooting with the electronic service tool.Caterpillar Electronic Technician (Cat ET) - Cat ET is a Caterpillar electronic service tool that is used for diagnosing and programming a variety of electronic controls.Caterpillar Engine Monitoring - The part of the Caterpillar Electronic Engine Control that monitors coolant temperature, oil pressure, inlet manifold air temperature, and coolant level. Caterpillar engine monitoring then informs the operator of any problems that are detected. The Coolant Temperature, Inlet Manifold Air Temperature, and Oil pressure Sensors are supplied by Caterpillar and Monitored by the ECM. The coolant level sensor is installed by the OEM factory but still monitored by the ECM. This is opposed to an aftermarket Engine Monitoring System. An aftermarket Engine Monitoring System does not interface with the Caterpillar Electronic Engine Control.Clutch Switch - The clutch switch is supplied by the OEM factory. The clutch switch is a limit switch. The usually adjustable switch is mounted near the pedal. When the pedal is released, the switch is closed. Depressing the clutch will open the circuit.Code - See the Diagnostic Code.Coolant Fan Relay - The relay is supplied by the OEM manufacturer. The installed relay is controlled by the ECM. The ECM controls the cooling fan relay. The ECM uses the following information to control the cooling fan relay: coolant temperature and the high pressure switch on the air conditioner.Coolant Level Sensor - The sensor is installed by the OEM factory. The sensor detects the absence of coolant at the probe. The sensor also detects the presence of coolant at the probe. The sensor then sends the appropriate signal to the ECM.Coolant Temperature Sensor - The coolant temperature sensor measures the engine coolant temperature. The sensor sends a signal to the 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.Custom Data - The custom data is for monitoring purposes. The ECM stored trip data holds the custom data. The custom data allows the owner to specify operating parameters of the engine application.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.Dash Check Engine Lamp - The dash check engine lamp is sometimes called the diagnostic lamp. The dash check engine lamp is used to warn the operator of the presence of an active diagnostic code.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 an indication of a problem or event in the electrical engine systems.Diagnostic Event Code - These codes indicate an event. Diagnostic event codes are not necessarily an indication of problem within the electronic system.Diagnostic Fault Code - Diagnostic fault codes indicate an electronic system malfunction that indicates a problem with the electronic system.Diagnostic Flash Code - Diagnostic flash codes are used to indicate a malfunction within the electronic system. Diagnostic flash codes are also used to indicate an event that is detected by the electronic system. The codes are flashed on the dash check engine lamp.Diagnostic Lamp - A diagnostic lamp is sometimes called
