Rated 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 personality module 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.Speed Demand Input - The speed demand input is a signal that is sent to the ECM in order to calculate desired engine speed.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.Throttle Position - The throttle position is the interpretation by the ECM of the signal from the speed controller.Timing Calibration - The timing calibration is the adjustment of an electrical signal. This adjustment is made in order to correct the timing error between the
