862646 Mercruiser FUSE, Tan - 5 Ampere

based devices. These devices are compatible with the ATA (American Trucking Association) and with SAE Standards"Section J1587 and Section J1708". These devices include trip recorders, electronic dashboards and maintenance systems. The data link is also the medium for communication that is used for programming and troubleshooting with the Caterpillar electronic service tool.After Market Device - The customer or the machine (OEM) installs these devices or accessories. This installation is completed after the engine is delivered.Air-to-Air Aftercooler (ATAAC) - This is the method of using ambient air to cool inlet air after the inlet air has been through the turbocharger. The inlet air is then passed through an aftercooler (heat exchanger) before going to the inlet manifold. The aftercooler is mounted in the front of the radiator.Alternating Current (AC) - The direction of current flow changes. The current flow alternates constantly.American Wire Gauge (AWG) - This is the measurement of the diameter of electrical wire. This is also the measurement of the ability of electrical wire to carry current. A smaller AWG number reflects a larger wire.Atmospheric Pressure Sensor - This sensor measures atmospheric air pressure in the crankcase. The sensor sends the signal to the electronic control module (ECM).Before Top Center (BTC) - BTC is the 180 degrees of crankshaft rotation before the piston reaches Top Center in the normal direction of rotation.Boost Pressure Sensor - This sensor measures inlet manifold air pressure. The sensor sends the signal to the ECM.Bypass Circuit - This circuit substitutes an existing circuit. The circuit is usually a temporary circuit. The circuit is used for testing.Calibration - Calibration is an electronic adjustment of a sensor signal.Caterpillar Engine Monitoring - The part of the Caterpillar Electronic Engine Control that monitors Coolant Temperature, Oil Pressure, Inlet Manifold Air Temperature and Coolant Level. This will alert the operator of detected problems. The Coolant Temperature, Inlet Manifold Air Temperature, and Oil Pressure Sensors are supplied by Caterpillar and monitored by the ECM. The Coolant Level Sensor is installed by the OEM. This sensor is monitored by the ECM. An aftermarket Engine Monitoring System does not interface with the Caterpillar Electronic Engine Control.Check Engine Lamp - This is used to warn the operator of the presence of an active diagnostic code. This is also called the Diagnostic Lamp.Clutch Switch - This switch is supplied and installed by the OEM. The switch is an adjustable limit switch that is mounted near the pedal. The switch is normally closed when the pedal is released. Depressing the clutch will open the circuit.Coolant Level Sensor - This sensor detects the absence or presence of coolant at the probe. The sensor sends the signal to the ECM. This sensor is installed by the OEM.Cooling Fan Relay - This relay is supplied and installed by the OEM. The relay is controlled by the ECM. Coolant Temperature Sensor - This sensor detects the engine coolant temperature for Cold Mode operation and Caterpillar Engine Monitoring. If Engine Monitoring has been programmed to be OFF the sensor will not detect the engine coolant temperature.Customer Specified Parameter - The customer can set this parameter value. The parameter value is protected by Customer Passwords.Data Link - The data link is an electrical connection for communication with other onboard microprocessor based devices that use the data link. These devices are compatible with SAE Standards. These devices include trip recorders, electronic dashboards and maintenance systems. The data link is also the medium for communication that is used for programming and troubleshooting with the Caterpillar electronic service tool.Desired rpm - The desired engine speed (rpm) is input to the electronic governor within the ECM. The following criteria are used in order to determine the desired engine speed (rpm): the Throttle Position Sensor, the Speed-timing Sensor and the Customer Parameters.Desired Timing Advance (DES Timing ADV on ECAP) - The fuel injection timing advance is calculated by the ECM. The calculation is used to meet emission and performance specifications.Diagnostic Code - A diagnostic code is an indication of a problem or event in the electronic system.Diagnostic Event Code - These codes indicate an event. The codes are not necessarily an indication of a problem within the electronic system.Diagnostic Fault Code - These codes indicate an electronic system malfunction which will indicate a problem with the electronic system.Diagnostic Flash Code - This code indicates a malfunction of the electronic system. This code can also indicate an event that is detected by the electronic system. The code is Check Engine/Diagnostic Lamp.Diagnostic Lamp - This is used to warn the operator of the presence of an active diagnostic code. This term is also referred to as the Check Engine Lamp.Direct Current (DC) - Direct current is the type of current that flows consistently in only one direction.Duty Cycle - See Pulse Width Modulation.Electronic Control Module (ECM) - The ECM is the engine's control computer. The ECM provides power to the electronics for the system. The ECM monitors the information that is input by the system. The ECM acts as a governor in order to control engine rpm.Electronic Control Module (ECM) Fan Control - The ECM may control the cooling fan through a relay that is installed by the OEM. The ECM controls the relay that is based on coolant temperature, inlet manifold air temperature, and boost pressure. The relay can also be controlled by the ECM when the following switches are installed by the OEM:air conditioning high pressure switch, PTO ON/OFF, manual fan override switch and retarder solenoidElectronic 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 Unit Injector (EUI) - The injection pump is a mechanically actuated, electronically controlled unit injector. The EUI combines the pumping, electronic fuel metering, and injecting elements into a single unit.Engine Speed-Timing Sensor - This sensor provides a Pulse Width Modulated signal to the ECM. The ECM interprets this signal as the crankshaft position
