that an electronic system malfunction is currently present. Refer to the term "Diagnostic Trouble Code" in this glossary.Aftertreatment - Aftertreatment is a system that is used to remove pollutants from exhaust gases. The system consists of a Diesel Oxidation Catalyst (DOC), a Diesel Particulate Filter (DPF), and a Selective Catalytic Reduction (SCR) system.Air-To-Air Aftercooler - An air-to-air aftercooler is a device that is used on turbocharged engines 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) - Alternating current is an electric current that reverses direction at a regular interval that is reoccurring.Ammonia Oxidizing (AMOX) catalyst - The AMOX catalyst removes any residual ammonia from the exhaust gas stream after completion of the Selective Catalytic Reduction (SCR) process.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.Inlet Manifold Pressure - The difference between the turbocharger outlet pressure and atmospheric pressure is commonly referred to as inlet manifold pressure. The sensor for the inlet manifold air pressure measures the amount of boost.Breakout Harness - The 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 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.Clean Emissions Module (CEM) - Refer to "Aftertreatment".Code - Refer to "Diagnostic Trouble Code".Cold Mode - Cold mode is a mode for cold starting and for cold engine operation. This mode is used for engine protection, reduced smoke emissions, and faster warm-up time.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.Customer Specified Parameters - A customer specified parameter is a parameter that can be changed in the ECM with the Electronic Service Tool. A customer specified parameter's value is set by the customer. These parameters are protected by customer passwords.Data Link - The Data Link is a serial communication port that is used for communication with other microprocessor-based devices.Derate - Certain engine conditions will generate event codes. Also, engine derates may be applied. The map for the engine derate is programmed into the ECM software. The 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 electronic governor uses the signal from the throttle position sensor, the
