CONTROL GP-ELECTRONIC 3E5370 - Caterpillar

Active Diagnostic Code - An active diagnostic code describes a condition that is currently present in order to alert the operator or the service technician of an abnormal parameter of engine operation. Refer to a diagnostic fault code.Aftermarket Device - An aftermarket device is a device or an accessory that is installed by the customer after the engine is delivered.Air Shutoff Solenoid - This device is used by the secondary Electronic Control Module (ECM) in order to stop the engine in case of an emergency.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.Alarm Control Electronic Control Module (ECM) - The ECM is required by the Marine Classification Society for compliance. This ECM sounds an alarm when certain parameters are not met.Alarm Horn - An audible device is used to warn the operator of a malfunction.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. The sensors are used in order to detect a change in temperature or pressure. The change is converted by the sensor to an electrical signal.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 ECM provides 5 VDC to the analog sensors.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 and in engine operation.Auxiliary Pressure Sensor - This sensor is an additional pressure sensor that is installed by the engine owner.Auxiliary Temperature Sensor - This sensor is an additional temperature sensor that is installed by the engine owner.Backup Electronic Control Module (ECM) Lamp - The backup ECM lamp indicates that the engine is operating on the secondary ECM.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.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
