The following list contains some of the functions of the monitoring system display:
The diagnostic codes of the ECM systems are displayed.
The settings for the ECM are displayed.
The machine status parameters are shown in real time.
The number of occurrences and the clock hour of the first occurrence and the last occurrence are displayed for each of the events, active codes, and logged codes.
The definition for each logged diagnostic code and each event is displayed.Troubleshooting Procedures
The diagnostic codes can be viewed with the monitoring system display or with Cat® Electronic Technician (Cat ET) Service Tool.Event Identifier (EID)
An event indicates a reading that is outside of normal operating ranges but within component limits. The data is seen as incorrect by the ECM but there is no fault in the component. An example might be a high oil temperature reading. The event will be identified by the ECM, the EID, and a time stamp.Note: To identify an event, an "E" will proceed the diagnostic code. See Illustration 4.Component Identifier (CID)
The component identifier is a four-digit number that represents a particular component on the machine. For example, each ECM that is connected to the Monitoring System Display has a number that is assigned. Refer to Troubleshooting, "Diagnostic Code List" for a list of all of the components of the machine control system.Note: CIDs range from 1 to 65534. Therefore, there is a possibility that a CID could be five digits.Failure Mode Identifier (FMI)
The codes for the Failure Mode Identifier are defined by SAE standards. The following table contains a Caterpillar version of definitions.
