that an electronic system malfunction is currently present. Refer to the term "Diagnostic Code" in this glossary.Aftertreatment - Aftertreatment is a system that is used to remove pollutants from exhaust gases. The system consists of an aftertreatment regeneration device (ARD), a diesel oxidation catalyst (DOC) and a diesel particulate filter (DPF).Aftertreatment Regeneration Device (ARD) - This item is sometimes referred to as the Cat Regeneration System (CRS). The ARD is a device that intermittently raises the temperature of the exhaust gases in order to regenerate the diesel particulate filter.Alternating Current (AC) - Alternating current is an electric current that reverses direction at a regular interval that is reoccurring.ARD Fuel Pump - The ARD fuel pump provides high-pressure fuel to the fuel system for the aftertreatment regeneration device.Before Top Center (BTC) - BTC is the 180 degrees of crankshaft rotation before the piston reaches the top dead 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.Cat Regeneration System - Refer to "Aftertreatment Regeneration Device".Clean Emissions Module - The Clean Emissions Module (CEM) includes all the components of the aftertreatment system.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
