manual commands. All computer systems need some type of operating system to function.Display - A Display is any gauge, indicator, or digital readout that is used to display machine data.Download - Downloading is the process of moving or transferring stored information from an electronic control to an off-board system such as a service tool. See "Upload".Electronic Control Module (ECM) - The ECM is an electronic control that monitors machine systems. The control also outputs commands to drive components. The term was formerly used to describe an electronic engine control.ET - Refer to Cat Electronic Technician (Cat ET).Fill Factor - The fill factor is determined by dividing the actual volume of the load by the maximum volume of the load. The fill factor is expressed as a percentage.Flash Files - Flash Files are software programs that contain instructions on the operation of electronic controls. The programs are transferred from the off-board service tool to any on-board electronic control. Refer to “Flash Programming”.Flash Memory - Flash Memory is solid-state memory that is used in electronic controls. The memory can be reprogrammed with an off-board service tool through a data link without being removed from the control. Other types of memory can only be programmed outside of the control.Flash Programming - Flash programming is a means of programming an electronic control. Flash programming is also used to update the software of a control. Flash programming is done with an off-board service tool instead of replacing the control or a personality module. This process involves the transfer of configuration software from the service tool to the electronic control. Communication is done over a data link. See “Flash Memory” and “Uploading”.Gage - Refer to Gauge.Gauge - A Gauge is a type of display device. The gauge is usually a circular shape with an indicator needle. The gauge can be a mechanical device or a solid-state device.Hardware (H/W) - Hardware is the electrical components and electronic components that make up an electrical system.Icon - An Icon is a symbol that is used instead of words to convey a message in any language.Input/Output (I/O) - Input/Output (I/O) is a term that describes the electronic circuits within an electronic control. These circuits are used as inputs and outputs. Input components are sensors and switches. Output components are horns, lamps, and solenoids.kPa - Refer to Kilopascal.Keypad - The keypad is a panel of keys much like the number pad used on a telephone. The keypad is used as an interface to the onboard electrical system.Key Start Switch - The key start switch is an automotive start switch. The key start switch includes the following functions: ON (relay), CRANK, and ACCESSORY.Kilopascal (kPa) - Kilopascal is a metric unit of pressure measurement. A pascal is a pressure of 1 newton per square meter. For comparison, 6.89 kPa equals 1 psi.List box - The List box is a rectangular box with scroll bars that often appears on a Monitoring System Display. A List Box contains a scrollable list of
