The alert indicator notifies the operator of an abnormal condition. +Battery - This pertains to any of the harness wiring which is part of the circuit that connects to the positive battery post. +Battery voltage is also referred to as system voltage.Component Identifier (CID) - The CID is a diagnostic code that tells which component or system is faulty. 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 fault, a fault must be on hold and a fault 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 Fault - A detected fault is a fault that has been found by the main display module. A service code that has been recorded for the fault 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 is available from service, status, tattletale or numeric readout mode.Display - Display refers to the gauges, indicators or readouts within the Caterpillar Monitoring System display area.Failure Mode Identifier (FMI) - An FMI is a diagnostic code that identifies the type of failure that has occurred.

An FMI and a CID identify the type of fault.Floating - The status or state of a control input that is not connected to a positive source or ground.Hard Wired - Hard wired refers to electrical connections made within the harness that are permanent. These soldered connections or crimped connections are not meant to be altered. Harness Code - Harness code refers to the grounded condition or 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 but the system must know the machine, that the system is installed on. Hold or On Hold - This pertains to the holding of diagnostic information that is shown in the display area when in the service mode. It
