Aftermarket deviceA device or accessory installed by the customer after the vehicle is delivered. Air-To-Air Aftercooler (ATAAC)A means of cooling intake air after the turbocharger, using ambient air for cooling. The intake air is passed through an aftercooler (heat exchanger) mounted in front of the radiator before going to the intake manifold. Alternating Current (AC)The type of current where the direction of current flow changes (alternates) regularly and constantly. American Wire Gauge (AWG)A measure of the diameter (and therefore the current carrying ability) of electrical wire. The smaller the AWG number, the larger the wire. Before Top Dead Center (BTDC) or Before Top Center (BTC)The 180° of crankshaft rotation before the piston reaches Top Dead Center (normal direction of rotation). Boost Pressure SensorThis sensor measures inlet manifold air pressure and sends a signal to the ECM.. Bypass CircuitA circuit, usually temporary, to substitute for an existing circuit, typically for test purposes. CalibrationAs used here, is an electronic adjustment of a sensor signal. CodeSee Diagnostic Code. Customer Specified ParameterA Parameter that can be changed and whose value is set by the customer. Protected by Customer Passwords. Data LinkAn electrical connection for communication with other microprocessor based devices that are compatible with SAE Standard J1708/J1587 such as, electronic dashboards and maintenance systems. The Data Link is also the communication medium used for programming and troubleshooting with Caterpillar service tools. Desired RPMAn input to the electronic governor within the ECM. The electronic governor uses inputs from the Throttle Position Sensor, Engine Speed Sensor, and Customer Parameters to determine "Desired RPM". Desired Timing Advance ("Des Timing Adv" on ECAP)The injection timing advance calculated by the ECM as required to meet emission and performance specifications. Diagnostic CodeSometimes referred to as a "fault code", it is an indication of a problem or event in the 3176 System. Diagnostic LampSometimes referred to as the "check engine light", it is used to warn the operator of the presence of an active diagnostic code. Digital Diagnostic Tool (DDT)A Caterpillar Electronic Service Tool used for programming and diagnosing of the 3176 System. Direct CurrentThe type of current where the direction of current flow is consistently in one direction only. Duty CycleSee Pulse Width Modulation. Electronic Control Analyzer and Programmer (ECAP)A Caterpillar Electronic Service Tool used for programming and diagnosing a variety of electronic controls. An ECAP is needed for advanced diagnostic and programming functions not possible with a DDT. Electronic Control Module (ECM)The engine control computer that provides power to the 3176 electronics, monitors 3176 inputs and acts as a governor to control engine rpm. Electronic Engine Control (3176)The complete electronic system that monitors and controls engine operation under all conditions. Electronically Controlled Unit InjectorThe injection pump which is a mechanically actuated, electronically controlled unit injector combining the pumping, electronic fuel metering and injecting elements in a single unit. Engine Speed/Timing SensorProvides a Pulse Width Modulated Signal to the ECM, which the ECM interprets as crankshaft position and engine speed. Estimated Dynamic TimingThe ECM's estimate of
