Illustration 1 g01858875Rated Fuel Limit - This is a limit that is based on the power rating of the engine and on the engine rpm. The Rated Fuel Limit enables the engine power and torque outputs to conform to the power and torque curves of a specific engine model. These limits are in the flash file and these limits cannot be changed.Reference Voltage - Reference voltage is a regulated voltage and a steady voltage that is supplied by the ECM to a sensor. The reference voltage is used by the sensor to generate a signal voltage.Relay - A relay is an electromechanical switch. A flow of electricity in one circuit is used to control the flow of electricity in another circuit. A small current or voltage is applied to a relay in order to switch a much larger current or voltage.Secondary Speed/Timing Sensor - This sensor determines the position of the camshaft during engine operation. If the primary speed/timing sensor fails during engine operation, the secondary speed/timing sensor is used to provide the signal.Sensor - A sensor is a device that is used to detect the current value of pressure or temperature, or mechanical movement. The information that is detected is converted into an electrical signal.Short Circuit - A short circuit is a condition that has an electrical circuit that is inadvertently connected to an undesirable point. An example of a short circuit is a wire which rubs against a vehicle frame and this rubbing eventually wears off the wire insulation. Electrical contact with the frame is made and a short circuit results.Signal - The signal is a voltage or a waveform that is used in order to transmit information typically from a sensor to the ECM.Suction Control Valve (SCV) - The SCV is a control device in the high-pressure fuel pump. The ECM controls the pressure in the fuel rail by using this valve to control the amount of fuel that enters the chambers in the pump.Supply Voltage - The supply voltage is a continuous voltage that is supplied to a component in order to provide the electrical power that is required for the component to operate. The power may be generated by the ECM or the power may be battery voltage that is supplied by the engine wiring.System Configuration Parameters - System configuration parameters are parameters that affect emissions and/or operating characteristics of the engine.Tattletale - Certain parameters that affect the operation of the engine are stored in the ECM. These parameters can be changed by use of the electronic service tool. The tattletale logs the number of changes that have been made to the parameter. The tattletale is stored in the ECM.Theft Deterrent - This feature uses a four-digit code in order to prevent the engine from starting. The feature requires a password to be entered via the CAT ID."T" Harness - This harness is a test harness that is designed to permit normal circuit operation and the measurement of the voltage simultaneously. Typically, the harness
