present in order to alert the operator or the service technician of an electronic system malfunction. Refer to the term "Diagnostic Code" in this glossary for more information.Alternating Current (AC) - Alternating current is an electric current that reverses direction at a regular interval that is reoccurring.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.Analog Sensors - Analog sensors produce a DC output signal that can vary from +0.2 VDC to +4.8 VDC. The sensors are used to detect a change in temperature or pressure. The change is converted by the sensor to an electrical signal that is sent to the ECM.Analog Sensor Return - The common line (ground) for the analog sensor from the ECM is used as a ground for the analog sensors.Analog Sensor Supply - The +5 VDC supply from the ECM is used to power the analog sensors.ATA Data Link - The ATA Data Link is a two wire electrical connection for communication with other microprocessor based devices. These devices are compatible with Standards for the American Trucking Association and Standards for the SAE (J1587 and J1708). The most common use of the ATA Data Link on Caterpillar machines is flash programming.Atmospheric Pressure Sensor - The atmospheric pressure sensor measures barometric pressure. The sensor sends a signal to the ECM. The signal is used in engine control, in engine operation, and in calibration of other pressure sensors.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 - The difference between the turbocharger outlet pressure and the atmospheric pressure is commonly referred to as boost.Breakout Harness - The breakout harness is a test harness that is designed to connect into the vehicle harness or the engine harness. This connection allows a normal circuit operation and the connection simultaneously provides a breakout T in order to measure the signals.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.CAN Data Link - Refer to "Controller Area Network (CAN Data Link)".CAT Data Link (CDL) - The CAT Data Link (CDL) is a serial communication port that is used for communication with other microprocessor based devices.Caterpillar Electronic Technician (Cat ET) - Cat ET is an electronic service tool that uses a software program to run on a personal computer (PC). Cat ET is used to service Caterpillar products. This program has replaced the ECAP service tool.Caterpillar Engine Monitoring - Caterpillar Engine Monitoring is the part of the electronic engine control that monitors the sensors. This also warns the operator of detected problems.Caterpillar Monitoring System - The Caterpillar Monitoring System is a modular electronic display that communicates with the ECM via the CAT Data Link.Code - Refer to "Diagnostic Code" or "Event Code".Cold Mode - Cold mode is a mode for cold starting and for cold engine operation that includes timing that is retarded and low idle that is raised. This mode is used for engine protection, reduced smoke emissions and faster warm up time.Component Identifier (CID) - The CID is a number that identifies the specific component of the electronic control system that has experienced a diagnostic code.Communication Adapter Tool - The communication adapter provides a communication link between the ECM and the Caterpillar Electronic Technician (Cat ET).Controller Area Network (CAN Data Link) - The CAN Data Link is a serial communications port that is used for communication with other microprocessor based devices. This is also referred to as the J1939 Data Link.Coolant Flow Switch - The coolant flow switch detects the absence or presence of coolant flow at the switch. The switch sends a signal to the ECM.Coolant Level Sensor - The coolant level sensor detects the absence or presence of coolant at the probe. The sensor then sends a signal to the ECM.Coolant Temperature Sensor - The coolant temperature sensor detects the engine coolant temperature for cold mode operation and the Caterpillar Engine Monitoring.Desired Engine Speed - The desired engine speed is input to the electronic governor within the ECM. The electronic governor uses the signal from the throttle position sensor, the engine speed/timing sensor, and other sensors in order to determine the desired engine speed.Diagnostic Code - A diagnostic code is sometimes referred to as a fault code. These codes indicate an electronic system malfunction.Diagnostic Lamp - A diagnostic lamp is sometimes called the check engine light. The diagnostic lamp is used to warn the operator of the presence of an active diagnostic code.Digital Sensors - Digital sensors produce a pulse width modulated signal. Digital sensors are supplied with +8 VDC from the ECM.Digital Sensor Return - The common line (ground) from the ECM is used as a ground for the digital sensors.Digital Sensor Supply - The +8 VDC supply from the ECM is used to power the digital sensors.Direct Current (DC) - Direct current is the type of current that flows consistently in only one direction.DT, DT Connector, or Deutsch DT - This is a type of connector that is used on Caterpillar machines. The connectors are manufactured by Deutsch.Duty Cycle - Refer to "Pulse Width Modulation".Electronic Control Module (ECM) - The ECM is the control computer of the engine. the ECM provides power to the electronics. The ECM monitors data that is input from the sensors of the engine. The ECM acts as a governor in order to control the speed of the engine.Electronic Engine Control - The electronic engine control is a complete electronic system. The electronic engine control monitors the engine operation under all conditions. The electronic engine control
