CORE AS-AFTERCOOLER 2310293 - Caterpillar

- This term refers to the state of a diagnostic code. The diagnostic code is present when the diagnostic code is active.+Battery - This pertains to any of the harness wiring which is part of the circuit that connects to the positive battery post. The +battery and the system voltage can be used with the same meaning.+V - +V is a constant voltage that is supplied to a component in order to provide electrical power for the operation of the component. +V is provided by an electronic control module or the battery.Component Identifier (CID) - The CID represents a diagnostic code. The CID is the code which determines the component that is faulty in the system. The CID is a four digit code, that is located in the digital display area when the main display module is in service mode.Clear - This pertains to removing diagnostic information from the memory of the main display module. Before clearing a diagnostic code, a diagnostic code must be on hold and a diagnostic code must not be present.Connector Contact - A connector contact is the component of a harness connector that actually makes the electrical connection. Connector contacts are either pins or sockets. Detected Diagnostic Code - A detected diagnostic code is a diagnostic code that has been found by the main display module. A diagnostic code that has been recorded for the failure and diagnostic information is available when the main display module is in service mode.Diagnostic - Diagnostic refers to the showing, monitoring and/or recording of information that is abnormal. Diagnostic information for the propel ECM is available through service mode 1.Diagnostic Code - A diagnostic code is a failure of a component in an electronic system. A FMI and a CID identify the type of diagnostic code.Display - Display refers to the gauges, indicators or readouts within the Caterpillar Monitoring System display area.Duty Cycle - Time that a square wave signal is “HI” versus time the signal is “LOW”. Also see “PWM”.ECM - The ECM is the acronym for the Electronic Control Module.Event - Whenever the ECM records information, it is called an event. The ECM categorizes the events into either a diagnostic code event or a data event.Failure Mode Identifier (FMI) - An FMI is a diagnostic code that identifies the type of failure that has occurred. The FMI consists of two digit code which is preceded by the letter “F”. The FMI is shown on the ECM display after the CID when in service mode 1.Harness Code - The harness code refers to the grounded condition or the open condition of the five harness code inputs (connector contacts 3, 6, 12, 16, 22 and 31). The harness code provides the characteristics of the machine such as the size of the engine, idle speed, tire size and attachments. The Caterpillar Monitoring System operates on different machines. The system is installed on a machine. The system must know the type of machine.Hold or On-Hold - Hold or On-hold
