KIT-SEAL 2339207 - Caterpillar

Active Diagnostic Code - An active diagnostic code alerts the operator or the service technician that an electronic system malfunction is currently present. Refer to the term "Diagnostic Code" in this glossary.Alternating Current (AC) - Alternating current is an electric current that reverses direction at a regular interval that is reoccurring.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.Breakout Harness - A breakout harness is a test harness that is designed to connect into 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.CAN Data Link (see also J1939 CAN Data Link) - The CAN Data Link is a serial communications port that is used for communication with other microprocessor-based devices.Code - Refer to "Diagnostic Trouble Code".Communication Adapter Tool - The communication adapter provides a communication link between the ECM and the electronic service tool.Coolant Temperature Sensor - The coolant temperature sensor detects the engine coolant temperature for all normal operating conditions and for engine monitoring.Data Link - The data link is a serial communication port that is used for communication with other devices such as the electronic service tool.Derate - Certain engine conditions will generate event codes. Also, engine may be derated. The map for the engine derate is programmed into the ECM software. The type of derate can be one or more of three types: reduction of rated power, reduction of rated engine speed and reduction of rated machine speed for OEM products.Desired Engine Speed - The desired engine speed is input to the electronic governor within the ECM. The governor uses signals from the ECM, the speed/timing sensors, and other sensors to determine the desired engine speed.Diagnostic Trouble Code - A diagnostic trouble code is sometimes referred to as a fault code. These codes indicate an electronic system malfunction.Digital Sensor Return - The common line (ground) from the ECM is used as ground for the digital sensors.Digital Sensors - Digital sensors produce a pulse width modulated signal. Digital sensors are supplied with power from the ECM.Digital Sensor Supply - The power supply for the digital sensors is provided by the ECM.Direct Current (DC) - Direct current is the type of current that flows consistently in only one direction.DT, DT Connector, or Deutsch DT - This design is a type of connector that is used on this engine. The connectors are manufactured by Deutsch.Duty Cycle - Refer to "Pulse Width Modulation".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 also controls the engine operation under all conditions.Electronic Control Module (ECM) - The ECM is the control
